| 2 | Review on the Technological Development and Application of UAV Systems显示文摘Unmanned aerial vehicles(UAVs) are products of deep integration of aviation technology and Information technology(IT). The core factor of why the UAV industry can become a relatively independent industry and experience rapid development is the full penetration of IT into the aviation industry. Under the networked environment, UAVs are now becoming datadriven mobile agents. With the development of information technology, information transmission networking, operation space digitizing, and flight platform intelligentizing will become the main trends of technological development of UAV systems. The application of UAV systems is not merely a paradigm in transportation, but will more importantly produce 'UAV+' novel production modes,service formats, and combat modes associated with UAVs.These emerging trends will have profound impacts on future economic and social development as well as the building of armed forces. | FAN Bangkui LI Yun ZHANG Ruiyu FU Qiqi | 2020 | Chinese Journal of Electronics2020，29，2： | 26 |
| 3 | Experimental investigation on static/dynamic characteristics of a fast-response pressure sensitive paint显示文摘An optical-based technique using Pressure-Sensitive Paint(PSP) is a promising method to measure the distribution of surface pressure on an aerodynamic model. The static and dynamic characteristics of a fast-response PSP that is developed in the Chinese Academy of Sciences(CAS)are analyzed and tested to serve as the basis for experiments on unsteady surface measurement using a fast-response PSP. Two calibration systems used for this study are set up to investigate the temperature dependency, response time, and resolution. A data processing method, used for dynamic data, is analyzed and selected carefully to determine the optimum signal. Results show that the fastresponse PSP can be used normally at temperatures from 25 ℃ to 80 ℃. The effect of temperature on the accuracy of the measurement must be considered when temperatures are beyond the temperature range of 30–40 ℃. The dynamic calibration device with a solenoid valve can achieve a pressure jump within a millisecond order. The resolution is determined by the signal-to-noise ratio of the photo-multiplier tube. Results of the measurement show that the response time of the PSP decreases with a large pressure variation, and the response time is below 0.016 s when the pressure variation is under 40 kPa. | Ruiyu LI Limin GAO Tianlong ZHENG Guanhua YANG | 2018 | Chinese Journal of Aeronautics2018，31，6： | 8 |
| 4 | Influence of leading edge with real manufacturing error on aerodynamic performance of high subsonic compressor cascades显示文摘To investigate the influence of real leading-edge manufacturing error on aerodynamic performance of high subsonic compressor blades,a family of leading-edge manufacturing error data were obtained from measured compressor cascades.Considering the limited samples,the leadingedge angle and leading-edge radius distribution forms were evaluated by Shapiro-Wilk test and quantile–quantile plot.Their statistical characteristics provided can be introduced to later related researches.The parameterization design method B-spline and Bezier are adopted to create geometry models with manufacturing error based on leading-edge angle and leading-edge radius.The influence of real manufacturing error is quantified and analyzed by self-developed non-intrusive polynomial chaos and Sobol’indices.The mechanism of leading-edge manufacturing error on aerodynamic performance is discussed.The results show that the total pressure loss coefficient is sensitive to the leading-edge manufacturing error compared with the static pressure ratio,especially at high incidence.Specifically,manufacturing error of the leading edge will influence the local flow acceleration and subsequently cause fluctuation of the downstream flow.The aerodynamic performance is sensitive to the manufacturing error of leading-edge radius at the design and negative incidences,while it is sensitive to the manufacturing error of leading-edge angle under the operation conditions with high incidences. | Chi MA Limin GAO Haohao WANG Ruiyu LI Baohai WU | 2021 | Chinese Journal of Aeronautics2021，34，6： | 7 |
| 5 | Synthesis, Characterization and Evaluation of Sulfur Transfer Catalysts for FCC Flue Gas显示文摘In this work, Zr-M(M=Cu, Mn, Ce) type sulfur transfer agent was prepared by impregnation method. Under the condition similar to that in the regenerator of FCC units, the influence of different active metal components and their contents on sulfur transfer agent were investigated. Moreover, the crystalline structure of sulfur transfer agent was characterized by X-ray diffraction(XRD) and Fourier transforms infrared spectroscopy(FT-IR). The result showed that the Zr-Mn sulfur transfer agent could effectively reduce the SO2 content in FCC regenerator flue gas, featuring high SO2 adsorption capacity. The sulfur transfer agent was inactivated in 40—60 min during the test. In the course of reduction reaction, after several reaction cycles, the formation of SO2 ceased and only H2 S was detected as the reduction product. | Jiang Ruiyu Shan Honghong Zhang Jiling Yang Chaohe Li Chunyi | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，2： | 5 |
| 6 | Effects of cerium precursors on surface properties of mesoporous CeMnO_x catalysts for toluene combustion显示文摘Mesoporous CeMnOx composite oxides catalysts were prepared by surfactant-assisted co-precipitation method and used for the catalytic oxidation of toluene.The effect of different cerium precursors[Ce(NO3)3 and(NH4)2 Ce(NO3)6] on catalyst structure,surface properties and toluene combustion activities of mesoporous CeMnOx catalysts were investigated.The Ce(Ⅲ)MnOx catalyst prepared from Ce(NO3)3 precursor shows higher catalytic activity,with a 90% conversion temperature of 240℃,which is better than the Ce(Ⅳ)MnOx catalyst derived from[(NH4)2 Ce(NO3)6] precursor.On the basis of characterizations,it reveals that abundant surface content of Mn4+,better redox behavior and larger concentration of surface active oxygen species are responsible for the excellent catalytic performance. | Changyu Zhang Wei Chu Feng Chen Lei Li Ruiyu Jiang Jinlong Yan | 2020 | Journal of Rare Earths2020，38，1： | 4 |
| 7 | Preparation and characterization of Mn/MgAlFe as transfer catalyst for SO_x abatement显示文摘A series of manganese-promoted MgAlFe mixed oxides, used as sulfur transfer catalysts, were prepared by acid-processed gelatin method and characterized by TGA-DTA, XRD, N2 adsorption-desorption and FT-IR techniques. It was found that the sulfur transfer catalysts with 0.5?3.0 wt% manganese showed its good dispersion in the precursor. The novel Mn/MgAlFe catalysts with 0.5?5.0 wt% manganese oxide showed a high oxidative adsorption rate and sulfur adsorption capacity, and 5.0 wt% Mn/MgAlFe sample was superior to the others for SO2 removal. Moreover, the presence of CO had no obvious effect on the adsorption activity of sulfur transfer catalysts for SO2 uptake. | Ruiyu Jiang Honghong Shan Chunyi Li Chaohe Yang | 2011 | Journal of Natural Gas Chemistry2011，20，2： | 4 |
| 8 | Application of shear-sensitive liquid crystal coating to visualization of transition and reattachment in compressor cascade显示文摘The present paper aims at introducing Shear-Sensitive Liquid Crystal Coating(SSLCC)technology into compressor cascade measurement for the first time and serves as a basis for better understanding of the influence from the boundary layers. Optical path layout, which is the most significant difficulty in internal flow field measurement, will be solved in this paper by selfdesigned image acquisition device. Massive experiments with different Mach number and incidence are conducted at a continuous subsonic cascade wind tunnel to capture the boundary layer phenomenon. Image processing methods, such as Three-Dimensional(3-D) reconstruction and Hue conversion, are used to improve the accuracy for transition position detection. The analysis of the color-images indicates that complex flow phenomena including transition, flow separation,and reattachment are captured successfully, and the effect of Mach number and incidence on the boundary layer flow is also discussed. The results show that: the Mach number has a significant effect on transition position; the incidence has little effect on transition position, but it has a great impact on the transition distance and leading-edge separation; influenced by the end-walls, the reattachment occurs in advance under positive angle of attack conditions. | Ruiyu LI Limin GAO Shuai ZHANG Yongzeng LI Tianyu GAO | 2018 | Chinese Journal of Aeronautics2018，31，11： | 4 |
| 9 | EFFECTS OF DIABETES ON HEARING AND COCHLEAR STRUCTURES显示文摘Diabetes mellitus(DM) is a chronic systemic disease characterized by hyperglycemia, with various pathogenic mechanisms. From absolute or relative insulin deficiency, patients with DM often demonstrate various levels of metabolic disorders. Major clinical manifestations of DM include metabolic disorders, vascular lesions, circulatory disturbances and neurologic complications. Along with advances in DM research, reports of DM related tinnitus and hearing impairment have increased continuously. Research on DM related auditory system dysfunction has focused on cochlear microcirculation, cellular homeostasis, genetics and aging. Cochlear microcirculation plays an important role in cochlear physiology and its disorders are associated with many inner ear diseases. Ischemia and subsequent reperfusion seen in cochlear microcirculation disorders are important factors in hearing damage. Understanding cochlear microcirculation and structural as well as functional changes in DM patients with hearing loss and their causal factors will help reveal pathogenic mechanisms in diabetic hearing loss and provide new ideas in developing interventions and preventing damages caused by diabetes. | Li Xipeng Li Ruiyu Li Meng Zhang Yanzhuo Guo Kaosan Wu Liping | 2013 | Journal of Otology2013，8，2： | 3 |
| 10 | Effect of H_2 Reduction Temperature on the Properties of Reduced Graphene Oxide and Copper Matrix Composites显示文摘Reduced graphene oxide(RGO) and copper composites(RGO/Cu) were successfully fabricated based on a molecular-level mixing method(MLM). The composite powders were reduced in H2 at 350, 450, and 550 °C and then consolidated by spark plasma sintering(SPS) in order to evaluate the effect of H2 reduction temperature on the properties of the composites. The results indicate that the strengths of the composite decrease with the increase of H2 reduction temperature, while the electrical conductivity reaches its maximum at 450 °C and minimum at 550 °C. Hot rolling could benefit the electrical conductivity. The yield strength of the RGO/Cu composite reduced to 337 MPa at 350 °C. The electrical conductivity of the RGO/Cu composite reduced at 450 °C after hot rolling reaches 60.26% IACS. The properties of the RGO/Cu composites can be designed by adjusting the reduction degree of RGO and by hot rolling. | Lidong Wang Ye Cui Ruiyu Li Guojian Cao Bin Li Weidong Fei | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，5： | 3 |
| 11 | Evaluation of the use of sublevel open stoping in the mining of moderately dipping medium-thick orebodies显示文摘The flow of blasted ore during mining of moderately dipping medium-thick orebodies is a challenge.Selecting a suitable mining system for such ore bodies is difficult.This paper proposes a diamond layout sublevel open stoping system using fan blastholes with backfilling to mine such orebodies.To evaluate the performance of system the relationships between ore recovery and stope footwall dip angle,footwall surface roughness,drawpoint spacing and production blast ring burden were investigated.An ore recovery data set from 81 laboratory physical model experiments was established from combinations of the listed factors.Various modules in a back propagation neural network structure were compared,and an optimal network structure identified.An ore recovery backpropagation neural network(BPNN)forecast model was developed.Using the model and sensitivity analysis of the factors affecting the proposed open stope mining system,the significance of each factor on ore recovery was studied.The study results were applied to a case study at the Shandong Gold Group Jiaojia Gold Mine.The results showed that the application of a BPNN and sensitivity analysis models for ore recovery prediction in the proposed mining system and field experimental results confirm that the suggested mining method is feasible. | Shuai Xu Ruiyu Liang Fidelis TSuorineni Yuanhui Li | 2021 | International Journal of Mining Science and Technology2021，31，2： | 3 |
| 12 | Effect of hypoglycemic anti-deafness capsules in diabetic patients with deafness and toxicological assessment in rats显示文摘OBJECTIVE:Through experiment on animals and clinical trials to explore the safety and efficacy of hypoglycemic anti-deafness capsules on diabetic patients with deafness.METHODS:Total 296 patients with non-insulin dependent diabetes mellitus(NIDDM)were randomly divided into two groups.A treatment group of 164patients(208 ears)was treated with hypoglycemic anti-deafness capsules based onTCM syndrome differentiation.A control group of 132 patients(184ears)was treated with glibenclamide and conventional drug treatment for deafness.The following were observed:hearing,fasting plasma glucose(FPG),2 h postprandial plasma glucose(2hPG),24 h urine glucose(24hUG),improvement of main symptoms,platelet function,and changes in superoxidedismutase(SOD)and lipid peroxide(LPO)levels.In animal studies,Kunming mice,weighing 18-22 g were used.Half of the mice were males and half were females.Wistar rats,weighing 80-120 g were used.Half of the rats were males and half were females.Male Wistar rats,weighing 200-220 g,were also used.Their acute and chronic toxicity was studied.RESULTS:The hearing improvement was 56.7%in the treatment group and 26.6%in the control group.FPG,2hPG,and 24hUG were improved significantly(P<0.05,P<0.01,P<0.01,respectively)in the treatment group and 2hPG and 24hUG improved significantly in the control group(P<0.05,P<0.05).The improvement in 2hPG and 24hUG in the treatment group was significantly greater than that in the control group P<0.01).There was no significant difference in FPG between the two groups(P<0.05).Main symptoms in the treatment group were significantly more improved than those in the control group(P<0.05,P<0.01).In the treatment group,platelet adhesion and aggregation,SOD,and LPO were all significantly improved from before treatment(P<0.05,P<0.01).However,in the control group,except LOP(P<0.05),there were no significant differences from before treatment to after(P<0.05).In animal studies,no obvious acute or long-term toxicity was observed from capsule administration.CONCLUSION:Through experiment on animals and clinical trials,we can found that hypoglycemic anti-deafness capsules could decrease blood glucose and serum triglycerides of alloxan-induced diabetic rats.This herbal capsule is effective for safely treating diabetic patients with deafness. | Ruiyu Li Meng Li Kaoshan Guo Bin Li Jinjie Hou Liping Wu Xianyun Liu | 2013 | Journal of Traditional Chinese Medicine2013，33，5： | 2 |
| 13 | Experimental Investigation of a Linear Cascade with Large Solidity Using Pressure Sensitive Paint and Dual-Camera System显示文摘Pressure Sensitive Paint(PSP)technique has been increasingly applied to the experimental research of aerodynamics and thermodynamics due to its strengths of non-contact,high resolution results and large coverage area,etc.However,rarely has this technique been successfully used to the study of internal flow such as compressor cascade,since narrow flow passages would heavily restrict the acquisition of PSP images.In this paper,PSP technique was used to study the pressure distribution on a linear compressor cascade with large solidity of 2.3,where the view of recording camera can be heavily blocked due to adjacent blade surfaces.To help get integrated PSP images of the internal flow passage,dual camera system along with image processing tools like 3D reconstruction and image integration were adopted.The results showed that with the aid of such assistance,image results with good quality and readability could be obtained.Meanwhile,pressure data given by PSP were compared with data from traditional way of pressure taps and showed good consistency.Massive results of the entire cascade passage surface were given with different inlet Mach numbers and incidence angles.The results showed that PSP technique can integrally measure cascade tunnel of large solidity with the help of dual-camera system. | GAO Limin YANG Guanhua GAO Tianyu LI Ruiyu HU Xiaoquan | 2021 | Journal of Thermal Science2021，30，2： | 1 |
| 14 | A robust graphene oxide memristor enabled by organic pyridinium intercalation for artificial biosynapse application显示文摘Graphene oxide(GO)-based memristors offer the promise of low cost,eco-friendliness,and mechanical flexibility,making them attractive candidates for outstanding flexible electronic devices.However,their resistive transitions often display abrupt change rather than bidirectional progressive tuning,which largely limits their applications for biological synapse emulation and neuromorphic computing.Here,a memristor with a novel layered structure of GO/pyridinium/GO is presented with tunable bidirectional feature.The inserted organic pyridinium intercalation succeeds in serving as a satisfactory buffer layer to intrinsically control the formation of conductive filaments during device operation,leading to progressive conductance regulation.Thus,the essential synaptic behaviors including analog memory characteristics,excitatory postsynaptic current,paired pulse facilitation,prepulse inhibition,spike-timing-dependent plasticity,and spike-rate-dependent plasticity are replicated.The emulation of brain-like“learning-forgetting-relearning”process is also implemented.Additionally,the instant responses of the memristor can be stimulated by low operational voltages and short pulse widths.This study paves one way for GO-based memristors to actuate appealing features such as bidirectional tuning and fast speed switching that are desirable for the development of bio-inspired neuromorphic systems. | Yang Li Songtao Ling Ruiyu He Cheng Zhang Yue Dong Chunlan Ma Yucheng Jiang Ju Gao Jinghui He Qichun Zhang | 2023 | Nano Research2023，16，8： | 1 |
