| 1 | The effects of EGR and ignition timing on emissions of GDI engine显示文摘The effects of EGR and ignition timing on engine emissions and combustion were studied through an experiment carried out on an air-guided GDI engine.The test results showed that the ignition timing significantly affected the GDI engine emissions,that the NOx emissions significantly reduced when the ignition timing was retarded,and that NOx emissions decreased with the EGR level increasement.A higher EGR rate could reduce CO emissions while the CO emissions were less affected by the ignition timing.The HC emissions decreased at a lower EGR rate.At 2500 r/min,an appropriate EGR rate could cut down CO emissions.The exhaust gas temperature could significantly decrease with improving the EGR rate,and the exhaust gas temperature at 2500 r/min was clearly higher than that at 1850 r/min.The nucleation mode particles increased clearly,the accumulation mode particle number decreased gradually with the increase of EGR rate,and the typical particle size of nucleation mode particle was in the range of 10–25 nm. | ZHAO LiFeng YU XiuMin QIAN DingChao DONG Wei SUN Ping HE Ling YANG Song | 2013 | Science China(Technological Sciences)2013，56，12： | 5 |

| 5 | Improved crystallinity and self-healing effects in perovskite solar cells via functional incorporation of polyvinylpyrrolidone显示文摘Air moisture is the key issue for perovskites which invades the films and accelerates the damage of devices. Here, polyvinylpyrrolidone(PVP) is introduced to the methylammonium lead iodide(MAPbI_(3)) perovskite precursor to control crystal growth and endow the devices with self-healing ability in a moisture environment. The strong C=O...ΗAΝ hydrogen bonding interactions between PVP and MAPbI_(3) was confirmed by nuclear magnetic resonance measurements. By introducing hydrogen bonding in the MAPbI_(3)-based PSCs, we form a compact perovskite film of excellent electronic quality with a power conversion efficiency(PCE) of up to 20.32%. Furthermore, the O...ΗAΝ hydrogen bonding interactions at the grain boundaries suppress the decomposition of methylammonium cations and improve the recyclable dissolution–recrystallization of perovskite. As a result, the MAPbI_(3)-PVP based cells exhibited striking moisture stability and self-healing behavior, with negligible decay in efficiency after 500 h of operation in high humidity(65% ± 5% relative humidity) and rapid recovering ability after their removal from the humid environment. | Yunjuan Niu Dingchao He Zhengguo Zhang Jun Zhu Tulloch Gavin Polycarpos Falaras Linhua Hu | 2022 | Journal of Energy Chemistry2022，31，5： | 1 |

| 8 | A statistical-based online cross-system fault detection method for building chillers显示文摘Practical applications of data-driven fault detection(FD)are limited by their portability.The costs of model training and validation are extremely high when each system requires a model retrained on its own fault and fault-free data.Therefore,this paper proposes a statistical-based online cross-system FD method to address the problem of model portability.The proposed FD model can be cross-utilized between building chillers with various specifications while it only needs to update the original fault detection model by the normal operation data of the new chiller system,thus saving huge fault experimental costs for the fault detection of new chiller.First,a theoretical basis for the proposed cross-system fault detection method is presented.Then,experiments were conducted on three building chillers with different specifications.Both fault and fault-free data were collected from the three chillers.The development and validation of the proposed cross-system fault detection method are then conducted.Results show that the cross-system fault detection models perform well when used with different chillers.For instance,when the fault detection model of system#1 was cross-utilized to system#2,the detection accuracies of refrigerant leakage,refrigerant overcharge,and reduced evaporator water flow were 99.73%,90.17%,and 96.94%,respectively.Compared with original models,the detection accuracies were improved by 33.78%,84.07%,and 65.56%,respectively.Therefore,the proposed cross-system fault detection method has potential for online application to practical engineering FD. | Jiangyan Liu Xin Li Guannan Li Chuang Wu DingChao Li Qing Zhang Kuining Li Hailong Lu Yunqian Zhang Jinjiang Zhang | 2022 | Building Simulation2022，15，8： | 0 |
| 9 | SWOT Analysis on Breeding R&D of Tropical Crops in China in the Context of Implementing UPOV Convention 1991 Act显示文摘This paper firstly reviewed development process of UPOV Conventions and briefly introduced current situation of protection of new tropical crop varieties in China. Using SWOT approach,it analyzed internal strengths,weaknesses,external opportunities and threats of breeding R&D of tropical crops if implementing UPOV Convention 1991 Act in China. Internal strengths include rich resources,strategic significance of tropical crops,solid crop breeding foundation,and broad market prospect. Internal weaknesses include insufficient reserve of germplasm resources,weak R&D and protection of new varieties,low market level of breeding R&D entities,unreasonable structure,low input in breeding R&D,and weak protection awareness. Opportunities include bringing into play strengths of rich tropical plant resources,stimulating enthusiasm for new variety R&D and awareness for variety protection,promoting structural optimization of breeding input entities,raising technology level of breeding R&D,and promoting international cooperation of new variety protection. Threats include more strict restriction of intellectual property right,impact to weak fields of new variety R&D,and difficulty in implementing limitation of farmer privileges. Finally,it came up with four recommendations for breeding R&D of tropical crops in China in the contest of implementing UPOV Convention 1991 Act. | Wenhui PU Dingchao DONG Qiong LI Huijian ZHANG | 2015 | Asian Agricultural Research2015，7，8： | 0 |
