| 2 | Analysis of Cu,Co,V and Zn in Coastal Waters of the East China Sea by Inductively Coupled Plasma Mass Spectrometry(ICP-MS)显示文摘In this study, a simple method for the simultaneous determination of trace metals(Cu, V, Co, Zn) in coastal seawater using the Mg(OH)2 coprecipitation inductively coupled plasma mass spectrometry(ICP-MS) was developed. This multi-element method enables the simultaneous extraction of four metals, particularly Co and V. The recoveries of Cu, Co, V and Zn after Mg(OH)2 coprecipitation were 73%, 96%, 94% and 92%, which means that our procedure was well-suited to the determination of these four trace metals. The detection limits were 3.81, 0.18, 6.09 and 1.91 nmol L-1, respectively. Then, applying this method to the simultaneous determination of these four metals in coastal water samples from the East China Sea revealed that the concentrations of Cu, Zn, Co and V were higher in bottom waters compared to water at other depths, and higher concentrations were generally observed at the Yangtze River estuary. Additionally, example vertical profiles of dissolved trace metal concentrations for the East China Sea in spring and autumn are compared. These findings indicate that Zn had the greatest seasonal variation followed by Cu, V and Co. For Zn and Co, the concentrations were higher during spring than during autumn. For Cu and V, the seasonal variation in the concentrations was opposite. | YANG Rujun NING Yutong ZHANG Aibin LI Yan SU Han | 2016 | Journal of Ocean University of China2016，15，5： | 1 |
| 3 | Characterization of iron diagenesis in marine sediments using refined iron speciation and quantized iron(Ⅲ)-oxide reactivity:a case study in the Jiaozhou Bay,China显示文摘As a case study, refined iron(Fe) speciation and quantitative characterization of the reductive reactivity of Fe(Ⅲ)oxides are combined to investigate Fe diagenetic processes in a core sediment from the eutrophic Jiaozhou Bay.The results show that a combination of the two methods can trace Fe transformation in more detail and offer nuanced information on Fe diagenesis from multiple perspectives. This methodology may be used to enhance our understanding of the complex biogeochemical cycling of Fe and sulfur in other studies. Microbial iron reduction(MIR) plays an important role in Fe(Ⅲ) reduction over the upper sediments, while a chemical reduction by reaction with dissolved sulfide is the main process at a deeper(> 12 cm) layer. The most bioavailable amorphous Fe(Ⅲ) oxides [Fe(Ⅲ)am] are the main source of the MIR, followed by poorly crystalline Fe(Ⅲ) oxides [Fe(Ⅲ)pc)]and magnetite. Well crystalline Fe(Ⅲ) oxides [Fe(Ⅲ)wc] have barely participated in Fe diagenesis. The importance of the MIR over the upper layer may be a combined result of the high availability of highly reactive Fe oxides and low availability of labile organic matter, and the latter is also the ultimate factor limiting sulfate reduction and sulfide accumulation in the sediments. Microbially reducible Fe(Ⅲ) [MR-Fe(Ⅲ)], which is quantified by kinetics of Fe(II)-oxide reduction, mainly consists of the most reactive Fe(Ⅲ)am and less reactive Fe(Ⅲ)pc. The bulk reactivity of the MR-Fe(Ⅲ) pool is equivalent to aged ferrihydrite, and shows down-core decrease due to preferential reduction of highly reactive phases of Fe oxides. | TAO Jing MA Weiwei ZHU Maoxu LI Tie YANG Rujun | 2017 | Acta Oceanologica Sinica2017，36，7： | 1 |

| 6 | Effects of TiO_2 volume fraction on the microstructure and magnetic properties of CoPt-TiO_2 nanocomposite films显示文摘CoPt-TiO2 nanocomposite films were synthesized by rapid thermal annealing of CoPt/TiO2 multilayers.The effects of TiO2 volume fraction on the microstructure and magnetic properties of the nanocomposite films were studied.Results showed that the ordering and texture of the L10-CoPt particles did not change with TiO2 content up to 76 vol.% of TiO2.However,the volume of the L10-CoPt particles in the film decreased with an increase in TiO2 content.Increasing TiO2 content effectively reduced the coalescence of magnetic grains when TiO2 content was larger than 56 vol.%.Both the out-of-plane coercivity and remanence ratio of the film decreased slightly with TiO2 content,but the in-plane coercivity and remanence ratio of the film decreased firstly and then increased after TiO2 content was larger than 56 vol.%.The reduction in the coercivity of the film should be due to the reduction in the size of the L10-CoPt particles.The reduction in remanence ratio might be due to the weakening of the exchange coupling strength between the magnetic grains when TiO2 content was increased,as indicated by the MFM images. | TANG RuJun ZHANG WanLi LI YanRong | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，7： | 1 |
| 7 | Regulating droplet impact symmetry by surface engineering显示文摘Droplet impact on solid surfaces is essential both in nature and industry.Precisely regulating the dynamic behavior of droplet impact is of great significance for energy harvesting,anti-icing,inkjet printing,pesticide spraying,and many other fields.Various rebounding behaviors(deposition,rebounding,rotation,instability control,and so on)and rebounding intrinsic parameters(such as contact time)after droplets impacting on solid surfaces can be regulated by surface engineering.This paper reviews the advances in regulating droplet impact behavior from the perspective of symmetry by modifying solid surfaces from the following aspects:chemical modification and physical structure regulation,in which the symmetry is discussed from mirror symmetry and rotational symmetry.Firstly,the symmetry of the droplet impact dynamics and its influencing factors are introduced.Then the modulation of droplet impact symmetry,using homogeneous and heterogeneous chemically modified solid surfaces,is summarized.The following presents the influence of physical structures,from micro to macro scale compared to the droplet size,on the droplet impact symmetry.Finally,the future challenges and opportunities of the droplet impact behavior regulation are discussed。 | Zhipeng Zhao Huizeng Li Quan Liu An Li Luanluan Xue Renxuan Yuan Xinye Yu Rujun Li Xiao Deng Yanlin Song | 2023 | Droplet2023，2，2： | 1 |
| 8 | 胰管内黏液乳头状瘤的MSCT和MRCP表现(英文)显示文摘Objective:To study the multi-slice CT(MSCT) and magnetic resonance cholangio-pancreatography(MRCP) features of intraductal papillary mucinous tumor(IPMT) of the pancreas.Methods:The clinical information,laboratory val-ues,imaging features and pathological findings of 8 cases were reviewed.Results:There were 6 males and 2 females with average 71.3 years old in this series.These lesions involved pancreatic branch ducts or main duct.Among them,2 cases were involved in the pancreatic uncinate process,1 case in the pancreatic head,1 in the pancreatic body,2 in the pancreatic tail and 2 cases involved multiple pancreatic duct.The common complaint was chronic upper abdominal pain.The imaging features included cystic lesion and it's association with the dilated pancreatic main duct,and bulging of the duodenal papilla.Mucin plug,septa or mural nodule were found in these cystic lesions.5 cases were confirmed with endoscopic retrograde cholangio-pancreatography(ERCP).3 cases had undergone surgery.Pathological findings of the 3 cases were adenoma,adenocarcinoma and borderline tumor,respectively.Conclusion:The MSCT and MRCP features of IPMT are somewhat characteristic,and the correct diagnosis can be made with the combination of clinical features.Diameter of branch duct ≥ 3 cm with multiple or large mural nodules,or severe dilated main duct indicates the probability of malignant IPMT. | Bin Yang Wenhui Chen Xiaofeng Zhang Yixin Yu Xiao Li Rujun Xu | 2008 | The Chinese-German Journal of Clinical Oncology2008，7，10： | 0 |

| 10 | Analysis of Risk Factors of Postoperative Neurological Complications in Patients with Stanford Type A Aortic Dissection Undergoing Sun’s Procedure显示文摘Objective:This study analyzed the risk factors of neurological complications in patients with Stanford type A aortic dissection after Sun’s procedure in a single-center with the purpose of improving the effects.Methods:From January 2019 to December 2020,the clinical data of 480 patients with Stanford type A aortic dissection,who were treated by Sun’s procedure in our center were retrospectively analyzed.Univariate and multivariate logistic regression analyses were used to determine the risk factors of postoperative neurological complications.According to whether there were neurological complications after surgery,they were divided into two groups:the group with complications(n=70)and the group without complications(n=410).The clinical data of the two groups were collected and compared.Results:There were 70 cases of patients with postoperative neurological complications in 480 cases.The incidence rates of temporary neurological dysfunction(TND)and permanent neurological dysfunction(PND)was 11.5%(55/480)and 3.1%(15/480),respectively.Univariate analysis showed that the age(≥70 years),stroke history,femoral artery intubation and cardiopulmonary bypass(CPB)time were associated with postoperative PND(p<0.05).Renal dysfunction,emergency surgery,postoperative hypernatremia,postoperative hyperglycemia,postoperative hypoxemia,postoperative low cardiac output syndrome,and assisted time of suction influenced the occurrence of postoperative TND(p<0.05).Multivariate logistic regression analysis showed that age(≥70 years),stroke history,femoral artery intubation and CPB time were independent risk factors for PND.Renal dysfunction,emergency surgery,postoperative hypernatremia,postoperative hyperglycemia,postoperative hypoxemia,postoperative low cardiac output syndrome,and aspiration time were independent risk factors for TND.Compared with the two groups,the hospitalization time and ICU time of the patients in the neurological complications group were significantly prolonged,and the mortality rate was significantly increased(p<0.05).Conclusion:There are many risk factors for neurological complications in patients with Stanford type A aortic dissection after surgery.With the improvement of surgical techniques,optimization of cerebral perfusion,and interventions for risk factors,Sun’s procedure remains the preferred treatment for Stanford type A aortic dissection. | Hui Zhang Ruicheng Zhang Hua Zhang Feng Li Jianming Zhao Shen Ma Rujun Zhu Pingfan Wang | 2021 | Journal of Clinical and Nursing Research2021，5，6： | 0 |
| 11 | Theoretical exploration of water injection gravity flooding oil in ultra-deep fault-controlled fractured-cavity carbonate reservoirs显示文摘Based on the analysis of geological characteristics of ultra-deep fault-controlled fracture-cavity carbonate reservoirs and division of reservoir units, two physical models were made, and physical simulations of oil displacement by water injection were carried out to find out water flooding mechanism in the fault-controlled fracture-cavity carbonate reservoir under complex flow state. On this basis, a mathematical model of fault-controlled carbonate reservoir with coexisting seepage and free flow has been established. Pilot water injection tests have been carried out to evaluate the effects of enhancing oil recovery by water injection. The results show that: fault-controlled fracture-cavity carbonate reservoir units can be divided into three types:the strong natural energy connected type, the weak natural energy connected type and the weak natural energy isolated type;the fault-fracture activity index of the fault-controlled fractured-cavity body can effectively characterize the connectivity of the reservoir and predict the effective direction of water injection;the mathematical model of fault-controlled carbonate reservoir with coexisting seepage and free flows can quantitatively describe the fluid flow law in the fracture-cavity body;the water injected into the fault-controlled fracture-cavity body is weakly affected by the capillary force of the lithologic body, and the oil-water movement is mainly dominated by gravity. The development modes of single well water injection, unit water injection,and single well high pressure water injection proposed based on the connection structure of fracture-cavity space and well storage space configuration are confirmed effective by pilot tests, with obvious water injection gravity flooding effect. | YANG Xuewen WANG Rujun DENG Xingliang LI Shiyin ZHANG Hui YAO Chao | 2022 | Petroleum Exploration and Development2022，49，1： | 0 |
| 12 | Macrokinetics of Ethylene Epoxidation over A-type Silver Catalyst显示文摘By taking the surface chemical reactions as the rate-controlling step, a possible reaction mechanism for ethylene epoxidation to synthesize ethylene oxide over the A-type silver catalyst was developed, while it was assumed that the epoxidation reaction would take place between ethylene and the un-dissociated adsorbed oxygen O2 a on the solo active sites, while the deep oxidation would occur between ethylene and the dissociated adsorbed oxygen Oa on the adjacent multi-active sites. In order to describe the effect of 1,2-C2H4Cl2(EDC) inhibitor on the ethylene epoxidation process, the reversible reactions between EDC and vinyl chloride(VC) on the active sites of silver catalyst was introduced. According to the assumed mechanism, the hyperbolic macro-kinetic model of ethylene epoxidation over the A-type silver catalyst was established, and the macrokinetic experiments were carried out in an internal-recycle gradientless reactor operating at a pressure of 2.1 MPa and a temperature in the range of 217.8—249.0 ℃, with the gas composition(molar fraction) consisting of 15.82%—34.65% C2H4, 2.55%—7.80% O2, 0.88%—6.15% CO2, 0.15—2.61 μmol/mol of 1,2-C2H4Cl2 and 0.14—1.28 μmol/mol of C2H3 Cl. By means of the Simplex Optimal Method, the parameters of the macrokinetic models were estimated. Statistical test showed that the macrokinetic models developed for the A-type silver catalyst agree well with the experimental results. | Liang Rujun Li Jianwei | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，3： | 0 |
| 13 | Displacement Field Variable Modeling Method for Heterogeneous Materials in Wind Power Blade Core Plates显示文摘In order to study the mechanical properties of the heterogeneous core plate of the wind turbine blade,a modeling method of the core plate based on displacement field variables is proposed.Firstly,the wind turbine blade core plate was modeled according to the theory of modeling heterogeneous material characteristics.Secondly,the three-point bending finite element model of the wind turbine blade core plate was solved by the display dynamic equation to obtain the deformation pattern and force-deformation relationship of the core plate.Finally,the three-point bending static test was conducted to compare with the finite element analysis.The test results show that:the damage form of the wind turbine blade core plate includes elasticity,yield,and failure stages.The main failure modes are plastic deformation,core material collapse,and panel-core delamination.The failure load measured by the test is 1.59 kN,which is basically consistent with the load-displacement result obtained by the simulation,with a difference of only 1.9%,which verifies the validity and reliability of the model.It provides data references for wind turbine blade structure design. | Ying He Yongshuang Wen Xuemei Huang Leian Zhang Rujun Song Chang Li | 2023 | Energy Engineering2023，120，2： | 0 |
| 14 | Multiobjective trajectory optimization of intelligent electro-hydraulic shovel显示文摘Multiobjective trajectory planning is still face challenges due to certain practical requirements and mul-tiple contradicting objectives optimized simultaneously.In this paper,a multiobjective trajectory optimization approach that sets energy consumption,execution time,and excavation volume as the objective functions is presented for the electro-hydraulic shovel(EHS).The proposed cubic polynomial S-curve is employed to plan the crowd and hoist speed of EHS.Then,a novel hybrid constrained multiobjective evolutionary algorithm based on decomposition is proposed to deal with this constrained multiobjective optimization problem.The normalization of objectives is introduced to minimize the unfavorable effect of orders of magnitude.A novel hybrid constraint handling approach based onε-constraint and the adaptive penalty function method is utilized to discover infeasible solution information and improve population diversity.Finally,the entropy weight technique for order preference by similarity to an ideal solution method is used to select the most satisfied solution from the Pareto optimal set.The performance of the proposed strategy is validated and analyzed by a series of simulation and experimental studies.Results show that the proposed approach can provide the high-quality Pareto optimal solutions and outperforms other trajectory optimization schemes investigated in this article. | Rujun FAN Yunhua LI Liman YANG | 2022 | Frontiers of Mechanical Engineering2022，17，4： | 0 |
