| 1 | A Kelch Motif-Containing Serine/Threonine Protein Phosphatase Determines the Large Grain QTL Trait in Rice显示文摘A thorough understanding of the genetic basis of rice grain traits is critical for the improvement of rice (Oryza sativa L.) varieties.In this study,we generated an F 2 population by crossing the large-grain japonica cultivar CW23 with Peiai 64 (PA64),an elite indica small-grain cultivar.Using QTL analysis,17 QTLs for five grain traits were detected on four different chromosomes.Eight of the QTLs were newly-identified in this study.In particular,qGL3-1,a newly-identified grain length QTL with the highest LOD value and largest phenotypic variation,was fine-mapped to the 17 kb region of chromosome 3.A serine/threonine protein phosphatase gene encoding a repeat domain containing two Kelch motifs was identified as the unique candidate gene corresponding to this QTL.A comparison of PA64 and CW23 sequences revealed a single nucleotide substitution (C→A) at position 1092 in exon 10,resulting in replacement of Asp (D) in PA64 with Glu (E) in CW23 for the 364th amino acid.This variation is located at the D position of the conserved sequence motif AVLDT of the Kelch repeat.Genetic analysis of a near-isogenic line (NIL) for qGL3-1 revealed that the allele qGL3-1 from CW23 has an additive or partly dominant effect,and is suitable for use in molecular marker-assisted selection. | Zejun Hu Haohua He Shiyong Zhang Fan Sun Xiaoyun Xin Wenxiang Wang Xi Qian Jingshui Yang Xiaojin Luo | 2012 | Journal of Integrative Plant Biology2012，54，12： | 41 |

| 4 | Methanation of carbon dioxide on Ni/ZrO_2-Al_2O_3 catalysts:Effects of ZrO_2 promoter and preparation method of novel ZrO_2-Al_2O_3 carrier显示文摘The novel nickel-based catalysts with a nickel content of 12 wt% were prepared with the zirconia-alumina composite as the supports. The new carriers, ZrO2 improved alumina, were synthesized by three methods, i.e., impregnation-precipitation, co-precipitation, and impregnation method. The catalytic properties of these catalysts were investigated in the methanation of carbon dioxide, and the samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscope (XPS), temperature-programmed reduction (TPR) and temperature-programmed desorption (TPD) techniques. The new catalysts showed higher catalytic activity and better stability than Ni/γ-Al2O3. Furthermore, as a support for new nickel catalyst, the ZrO2-Al2O3 composite prepared by the impregnation-precipitation method was more efficient than the other supports in the methanation of carbon dioxide. The highly dispersed zirconium oxide on the surface of γ-Al2O3 inhibited the formation of nickel aluminate-like phase, which was responsible for the better dispersion of Ni species and easier reduction of NiO species, leading to the enhanced catalytic performance of corresponding catalyst. | Mengdie Cai Jie Wen Wei Chu Xueqing Cheng Zejun Li | 2011 | Journal of Natural Gas Chemistry2011，20，3： | 33 |

| 6 | Experimental Study on Emission Performance of an LPP/TVC显示文摘A key issue in the commercial aircraft engine design is environmental acceptability, and designers are continually challenged to reduce emissions. In this paper, an experimental investigation is performed to evaluate the emission performance of a liquid-fueled trapped vortex combustor (TVC) under lean premixed prevaporized (LPP) mode. When operating as an LPP system, a TVC is fueled both in the cavities and in the main stream. The correlations between the emission performance and the total excess air ratio, the positions (4 positions) of the fuel injectors in the main stream, and the inlet temperature are obtained. Experi- mental results show that both the volume concentrations of unburnt hydrocarbon (UHC) and NOx (NO, NO2 usually grouped together as NOx) increase with the increase of total excess air ratio from 1.5 to 3.0; the emission performance relies heavily on the position of the main stream injector, and the best performance is achieved at Position 4 in the experiments; the increase of the inlet temperature impacts on the emission performance positively; the smallest volume concentrations of UHC and NOx obtained in the experiment are 94×10 6 and 2.3×10 6 respectively. This paper validates the feasibility of low emissions for an LPP/TVC and provides a reference for further optimization of TVCs. | JIN Yi HE Xiaomin ZHANG Jingyu JIANG Bo WU Zejun | 2012 | Chinese Journal of Aeronautics2012，25，3： | 17 |

| 8 | ELE restrains empty glumes from developing into lemmas显示文摘Although there is evident homology among reproductive organs when comparing Poaceae (grass) and eudicots, the identity of grass specific organs, such as lodicules, palea, lemma, and glumes has been the subject of a vast and largely inconclusive discussion. Here we provide some direct evidence to support the idea that the empty glumes of rice (Oryza sativa) are counterparts of lemmas. We show that the development of empty glumes is regulated by ELE (elongated empty glume), which belongs to a plant specific novel gene family. Mutations at the ELE locus cause elongated empty glumes, which mimic the lemmas and have the epidermal morphology of lemmas with four or five vascular bundles. As a nuclear-localized gene, ELE is specifically expressed at the empty glumes of immature spikelets, and its ectopic expression causes many floral development defects, including lemma-like palea, extra palea-like structures, elongated lodicules, extra stamens and stigmas. Our result suggests that empty glumes are lemmas of the sterile florets located at the lateral side of the rice spikelet, and ELE acts as a regulator restraining its growth to maintain its small size in wild-type plants. | Lilan Hong Qian Qian Keming Zhu Ding Tang Zejun Huang Ling Gao Ming Li Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010，37，2： | 11 |

| 10 | Effect of China's rapid development on its iconic giant panda显示文摘Anthropogenic factors affect biodiversity and have led to the contraction or extinction of animal populations worldwide.Here,we use historical demographic data,spanning the past 300 years,to show that a rapid distributional contraction of giant pandas took place during the 18th and 19th centuries alongside the increase in human population.Land-use also underwent a significant change across the areas where giant pandas were found because of government agricultural policy and the introduction of new crops.The impact of social development on giant pandas includes habitat loss and fragmentation,and range reductions.Our findings would facilitate the design of effective conservation strategies that seek to conserve and increase current habitats of this iconic species,especially in areas that our analysis has identified as places where pandas have suffered from high human pressure. | ZHU LiFeng HU YiBo ZHANG ZeJun WEI FuWen | 2013 | Chinese Science Bulletin2013，58，17： | 8 |
| 11 | Design and Performance of an Improved Trapped Vortex Combustor显示文摘A trapped vortex combustor (TVC) has been a very promising novel concept for it offers improvements in lean blow out, altitude relight, operating range, as well as a potential to decrease NOx emissions compared to conventional combustors. The present paper discusses the improved designs of the new combustor over the prior ones of our research group, including that:a) the over-all dimensions, both axial and radial, are reduced to those of an actual aero-engine combustor; b) the air flow distribution is optimized, and especially 15% of the air is fed into the liner as cooling air; c) a straight-wall diffuser with divergence angle 9°is added. A series of experiments (cavity-fueled only, under atmospheric pressure) has been conducted to investigate the performance of the improved TVC. Experimental results show that at the inlet temperature of 523 K, the inlet pressure of 0.1 MPa, stable operation of the TVC test rig is observed for the Mach number 0.15-0.34, indicating good flame stability; the combustion efficiency obtained in this paper falls into the range of 60%-96%; as the total excess air ratio increases, the combustion efficiency decreases, while the increase of the inlet temperature is beneficial to high combustion efficiency; besides, the optimal Mach numbers for high combustion efficiency under different inlet conditions are confirmed. The outlet temperature profiles feature a bottom in the midheight of the exit. This paper demonstrates the feasibility for the TVC to be applied to a realistic aero-engine preliminarily and provides reference for TVC design. | JIN Yi HE Xiaomin JIANG Bo WU Zejun DING Guoyu | 2012 | Chinese Journal of Aeronautics2012，25，6： | 8 |

| 16 | Blind reconnaissance of the pseudo-random sequence in DS/SS signal with negative SNR显示文摘This paper introduces a new theory and algorithm that can be used in blind detection of the carrier wave signal and the pseudo-random sequence of the direct sequence spread spectrum (DS/SS) signal with negative SNR. First, without any a priori knowledge of the DS/SS signal, the carrier wave signal can be detected from DS/SS signal with negative SNR by using stochastic differential equations and energy detection method. Based on this, the pseudo-random sequence can also be blindly detected in DS/SS signal with negative SNR by reducing noise of the nonlinear signal and the algorithm of wavelet multiscale decomposition algorithm. Finally, the computer simulation shows that we can detect the carrier wave signal with SNR=-27 dB and the pseudo-random sequence under error code ratio 10-4 with SNR =-10 dB. | HUANG XianGao HUANG Wei WANG Chao LU ZeJun HU YanHua | 2007 | Science in China(Series F)2007，50，3： | 6 |

| 18 | Modified Dachengqi Tang improves decreased gastrointestinal motility in postoperative esophageal cancer patients显示文摘OBJECTIVE:To investigate the clinical effects of modified Dachengqi Tang(DCQT) on promoting gastrointestinal motility in post-operative esophageal cancer patients.METHODS:Sixty postoperative esophageal cancer patients were enrolled and randomly assigned to the modified treatment group or the control group(30 patients in each group).Patients in the treatment group were given DCQT made from decocted herbs and administered via nasojejunal tube at a dosage of 150 mL.Gastrointestinal motility was assessed by recording time for recovery of bowel sounds,flatus,defecation,and the total amount of gastric drainage during the first three postoperative days.Plasma motilin(MTL) and vasoactive intestinal peptide(VIP) were measured one hour before and three days after surgery.RESULTS:Compared with the control group,the times to first bowel sound,flatus,and defecation were significantly shorter and there was less gastric drainage in the treatment group(P < 0.01,P < 0.01,P < 0.01,and P < 0.05,respectively).In the treatment group,postoperative plasma MTL was significantly higher(P < 0.01) and VIP was significantly lower than those in the control group(P < 0.05).There was no difference found in either MTL or VIP from before to after operation in the treatment group(P > 0.05).MTL was significantly lower and VIP was higher postoperatively in the control group,compared to before surgery(P < 0.01).CONCLUSION:Modified DCQT effectively improved decreased gastrointestinal motility in postoperative esophageal cancer patients by increasing MTL and reducing VIP. | Xu Zejun Xu Cuiping Ge Hongxia Li Yan Chu Liangliang Zhang Jie Cheng Kelin | 2015 | Journal of Traditional Chinese Medicine2015，35，3： | 5 |
| 19 | Design of soil moisture distribution sensor based on high-frequency capacitance显示文摘In order to obtain accurate real-time soil moisture data and the spatial distribution of soil moisture,the soil moisture measurement methods based on high-frequency capacitance edge field effect were analyzed,the structure of probe was studied,and a multi-channel soil moisture sensor was designed.Moreover,with the established two-dimensional trace planar capacitance probe model and the method of the finite element analysis,relationship between the structure of sensor probe and electric field intensity was studied and capacitance of the probe trace amount planar capacitance model was analyzed,the most optimal structure of sensor probe was determined.Design parameters of the probe which can achieve optimal sensitivity and detection range are:outer diameter 40 mm and inner diameter 38.4 mm for the probe copper ring electrode,axial length 20 mm and axial spacing 10 mm.The sensor is suitable for measuring the moisture of different type of soil.Moreover,the features of the profile soil moisture sensor were experimentally explored.The measurement accuracy reached±1.31%with better stability and consistency.Sensor probes can be assembled according to the measurement depth and used to measure soil moisture of different crop root zone. | Yan Hua Tang Zejun Xing Zhen Gao Dingneng Hong Haoxing | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 5 |
| 20 | Fabrication of Ti/Al/Mg laminated composites by hot roll bonding and their microstructures and mechanical properties显示文摘Ti/Al/Mg laminated composites were successfully fabricated by hot roll bonding.The effects of the rolling reduction on the microstructural evolution and mechanical properties of the composites were explored.The results show that Ti/Al/Mg laminated sheets exhibit good interfacial bonding.The rolling reduction has a significant effect on the deformation inhomogeneity through the thickness of the Al layer.The initial grains of the Al layer near the Ti/Al interface are fragmented into fine equiaxed grains,and the grains at the center and near the Al/Mg interface are elongated.The R-cube shear texture of the Al layer forms near the Ti/Al interface and permeates into the center layer in the samples with greater rolling reductions.The b-fiber rolling texture of the Al layer is observed near the Al/Mg interface and increases with the increase of rolling reduction.The stress–strain curves indicate that the fracture appears first in the Mg layer.With the increasing rolling reduction,the ultimate tensile and yield strength values increase,and the elongation up to the Mg layer fracture decreases. | Pengju WANG Zejun CHEN Hongtao HUANG Jianshu LIN Boxin LI Qing LIU | 2021 | Chinese Journal of Aeronautics2021，34，8： | 4 |
