| 1 | Estimation of lunar titanium content: Based on absorption features of Chang’E-1 interference imaging spectrometer (ⅡM)显示文摘Two linear regression models based on absorption features extracted from CE-1 IIM image data are presented to discuss the relationship between absorption features and titanium content. We computed five absorption parameters (Full Wave at Half Maximum (FWHM), absorption position, absorption area, absorption depth and absorption asymmetry) of the spectra collected at Apollo 17 landing sites to build two regression models, one with FWHM and the other without FWHM due to the low relation coefficient between FWHM and Ti content. Finally Ti content measured from Apollo 17 samples and Apollo 16 samples was used to test the accuracy. The results show that the predicted values of the model with FWHM have many singular values and the result of model without FWHM is more stable. The two models are relatively accurate for high-Ti districts, while seem inexact and disable for low-Ti districts. | LIU FuJiang*, QIAO Le, LIU Zheng, YANG Rong, SHI JinPing, ZHANG Ying & WU WeiLong Faculty of Information Engineering, China University of Geosciences, Wuhan 430074, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 8 |
| 2 | Combustion instability of pilot flame in a pilot bluff body stabilized combustor显示文摘Combustion instability of pilot flame has been investigated in a model pilot bluff body stabilized combustor by running the pilot flame only. The primary objectives are to investigate the pilot flame dynamics and to provide bases for the study of the interaction mechanisms between the pilot flame and the main flame. Dynamic pressures are measured by dynamic pressure transducers. A high speed camera with CH*bandpass filter is used to capture the pilot flame dynamics. The proper orthogonal decomposition(POD) is used to further analyze the high speed images. With the increase of the pilot fuel mass flow rate, the pilot flame changes from stable to unstable state gradually. The combustion instability frequency is 136 Hz when the pilot flame is unstable. Numerical simulation results show that the equivalence ratios in both the shear layer and the recirculation zone increase as the pilot fuel mass flow rate increases. The mechanism of the instability of the pilot flame can be attributed to the coupling between the second order acoustic mode and the unsteady heat release due to symmetric vortex shedding. These results illustrate that the pilot fuel mass flow rate has significant influences on the dynamic stability of the pilot flame. | Fu Xiao Yang Fujiang Guo Zhihui | 2015 | Chinese Journal of Aeronautics2015，28，6： | 5 |
| 3 | Applications of nanogenerators for biomedical engineering and healthcare systems显示文摘The dream of human beings for long living has stimulated the rapid development of biomedical and healthcare equipment.However,conventional biomedical and healthcare devices have shortcomings such as short service life,large equipment size,and high potential safety hazards.Indeed,the power supply for conventional implantable device remains predominantly batteries.The emerging nanogenerators,which harvest micro/nanomechanical energy and thermal energy from human beings and convert into electrical energy,provide an ideal solution for self-powering of biomedical devices.The combination of nanogenerators and biomedicine has been accelerating the development of self-powered biomedical equipment.This article first introduces the operating principle of nanogenerators and then reviews the progress of nanogenerators in biomedical applications,including power supply,smart sensing,and effective treatment.Besides,the microbial disinfection and biodegradation performances of nanogenerators have been updated.Next,the protection devices have been discussed such as face mask with air filtering function together with real-time monitoring of human health from the respiration and heat emission.Besides,the nanogenerator devices have been categorized by the types of mechanical energy from human beings,such as the body movement,tissue and organ activities,energy from chemical reactions,and gravitational potential energy.Eventually,the challenges and future opportunities in the applications of nanogenerators are delivered in the conclusive remarks. | Wanli Wang Jinbo Pang Jie Su Fujiang Li Qiang Li Xiaoxiong Wang Jingang Wang Bergoi Ibarlucea Xiaoyan Liu Yufen Li Weijia Zhou Kai Wang Qingfang Han Lei Liu Ruohan Zang Mark HRümmeli Yang Li Hong Liu Han Hu Gianaurelio Cuniberti | 2022 | InfoMat2022，4，2： | 2 |
| 4 | Isolation of a strong matrix attachment region (MAR) and identification of its function in vitro and in vivo显示文摘Inclusion of MARs in transgene cassettes enhances their expression and reduces position-effect variations in the transgenic host. Four new MARs (TM2, TM3, AM1 and AM2) were isolated from tobacco and Arabidopsis by PCR method. The nuclei isolated from suspension-cultured cells of rice were used to prepare nuclear matrix. With a characterized MAR (TM1) as a positive control, the Matrix-MAR interactions were tested by an in vitro binding assay to identify the DNA sequences as MARs and their binding strength to nuclear matrix in vitro was compared. The results showed that TM2 and TM3 had stronger binding strength than TM1. To determine the functions of the four new MARs in vivo, binary vectors pBI121 carrying a uidA GUS reporter gene were modified with direct repeat MARs inserted on both sides of the reporter gene cassette and were transferred into tobaccos via Agrobacterium-mediated transformation procedure. Quantitative GUS assays of the transgenic tobaccos showed that when flanking a GUS reporter gene | Kewei Zhang Jianmei Wang Guodong Yang Xingqi Guo Fujiang Wen Decai Cui Chengchao Zheng | 2002 | Chinese Science Bulletin2002，47，23： | 2 |

| 6 | Evidence of return of chum salmon released from Tangwang River by strontium marking method显示文摘In order to assess the effect of enhancement release of chum salmon(Oncorhynchus keta),otolith strontium(Sr)marking method was used to tag chum salmon released in Tangwang River in 2016.The homing chum salmon were detected and the samples were collected in Tangwang River,Ussuri River and Suifen River in the autumn of2018.The samples were analyzed by examining Sr and calcium(Ca)fingerprints in the otolith using electron probe microanalysis.The results suggested that two samples collected in Tangwang River had the marking ring near the core of otolith where the Sr concentration and Sr/Ca ratio were significantly higher than comparative samples.Proving that the two fish belonged to the released population in Tangwang River in 2016.This article indicated the success of the enhancement release of chum salmon from the Tangwang River for the first time and also confirmed the validity of Sr marking in enhancement release of fishes. | Jilong Wang Wei Liu Peilun Li Fujiang Tang Wanqiao Lu Jian Yang Tao Jiang | 2021 | Acta Oceanologica Sinica2021，40，8： | 1 |
| 7 | C-H BOND ACTIVATION AND FUNCTIONALIZATION OF METHANE UNDER MILD CONDITIONS显示文摘In the presence of Rh(COD)(dppe)Cl (COD=1, 5-cyclootadiene, dppe=1,2-bis-(diphenylphosphino)ethane) and CO, we studied the H/Cl exchange reaction between CH4 and o-dichlorobenzene, and observed that the active species of the reaction is a complex containing dppe and carbonyl ligands. We suggest that the mechanism of exchange reaction may be described by the elementary reaction of oxidative addition and reductive elimination. In the presence of trans-PtHL2X (L=PEt3, P(n-Pr)3, P(n-Bu)3, PPh3; X=Cl-, Br-, I-, CN-) complexes, we have studied the oxidative chlorination reaction of methane. The catalytic activity was found to be related to the electron-donating properties and the cone angle of tertiary phosphine, as well as the trans-effect of X anionic ligands. In addition to the above reactions, we have also studied the insertion reaction of acetylene into C-H bond of methane catalyzed by organotransition-metal complexes containing heterocyclic chelate ligands, such as bipy, phen and TMEDA, in | Zhang Liangfu , Ding Fujiang, Jin Hong, Jiang Qiongzhong,Yang Qi and Li Guangnian(Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, Chengdu, China) | 1990 | 分子催化1990，4，S1： | 0 |
| 8 | On the design of high-speed energy-efficient successive-approximation logic for asynchronous SAR ADCs显示文摘This paper analyzes the power consumption and delay mechanisms of the successive-approximation(SA) logic of a typical asynchronous SAR ADC,and provides strategies to reduce both of them.Following these strategies,a unique direct-pass SA logic is proposed based on a full-swing once-triggered DFF and a self-locking tri-state gate.The unnecessary internal switching power of a typical TSPC DFF,which is commonly used in the SA logic,is avoided.The delay of the ready detector as well as the sequencer is removed from the critical path.A prototype SAR ADC based on the proposed SA logic is fabricated in 130 nm CMOS.It achieves a peak SNDR of 56.3 dB at 1.2 V supply and 65 MS/s sampling rate,and has a total power consumption of 555 μW,while the digital part consumes only 203 μW. | Jiaqi Yang Ting Li Mingyuan Yu Shuangshuang Zhang Fujiang Lin Lin He | 2017 | Journal of Semiconductors2017，38，8： | 0 |
| 9 | GRASSLAND AGRICULTURE IN CHINA--A REVIEW显示文摘Interactions between crops and livestock have been at the core of the evolution of many agricultural systems.In this paper,we review the development and characteristics of mixed crop-livestock systems,with a focus on grassland-based systems,as these cover large areas in China,and face several challenges.Following the transition from the original hunting and foraging systems to a sedentary lifestyle with integrated crop-livestock production systems some 8000 years ago,a range of different mixed systems have developed,depending on rainfall,solar radiation and temperature,culture and markets.We describe 5 main types of integrated systems,(1)livestock and rangeland,(2)livestock and grain production,(3)livestock and crop-grassland rotations,(4)livestock,crops and forest(silvo-pasture),and(5)livestock,crops and fish ponds.Next,two of these mixed systems are described in greater detail,i.e.,the mountain-oasis-desert system and its modifications in arid and semi-arid regions,and the integrated crop-livestock production systems on the Loess Plateau.In general,crop-livestock interactions in integrated systems have significant positive effects on crop production,livestock production,energy use efficiency and economic profitability.We conclude that improved integration of crop-livestock production systems is one of the most important ways for achieving a more sustainable development of animal agriculture in China. | Fujiang HOU Qianmin JIA Shanning LOU Chuntao YANG Jiao NING Lan LI Qingshan FAN | 2021 | Frontiers of Agricultural Science and Engineering2021，8，1： | 0 |
