| 1 | Deep water bottom current deposition in the northern South China Sea显示文摘There are some active bottom currents on the northern continental slope of the South China Sea (SCS). Reflection seismic profiles show that the bottom current channels occur in the water depth range of 1000 to 2700 m,extending from the NE to the SW,leading to accumulation of discontinuous drifts with higher sedimentation rates on the eastern side of the channel. The stacking pattern of the layers sug-gests that these drifts propagated southwestward,following the direction of the bottom currents. One sedimentary drift to the southeast of the Dongsha Islands has the highest sedimentation rate of 97cm/ka in the last 12 ka. The sedimentary characteristics of the sediment layers indicate that these bottom currents are most likley caused by the water movement of a branch of the West Pacific Ocean Current,which enters the northern SCS via the Bashi Strait. Once formed,the bottom currents trans-port sediments along the northern slope of SCS southwestward and finally disappear into the central basin of the SCS. Due to the bottom current activity,the deep-sea sedimentary process in the northern SCS is complex. | SHAO Lei LI XueJie GENG JianHua PANG Xiong LEI YongChang QIAO PeiJun WANG LiaoLiang WANG HongBin | 2007 | Science China Earth Sciences2007，50，7： | 43 |
| 2 | 一种基于UML的实时工作流建模方法研究显示文摘实时系统由于其业务对时间要求的特殊性,使得传统工作流技术难以满足其需求.在传统工作流的基础上,针对实时系统提出了实时工作流的概念,并建立了实时工作流元模型.与传统的工作流相比,主要对工作流的时间约束和异常处理进行了考虑.在活动上扩展了启动时间和执行时间,在工作流过程上扩展了执行时间,在并发活动上扩展了并发时间约束等,此外,元模型中还考虑了活动的超时异常以及应用程序和活动之间的执行关系.为了能够利用实时工作流元模型进行实时工作流建模,通过扩展UML定义了一种实时工作流描述语言,并分别从设计要求、定义技术和profile三个方面对实时工作流描述语言进行了阐述,给出了实时工作流的建模规则.最后结合船舶指控系统的具体实例,对建模方法进行了说明. | 徐亮 张莉 樊志强 | 2010 | 计算机研究与发展2010，47，7： | 26 |

| 4 | Gear geometry of cycloid drives显示文摘According to differential geometry and gear geometry, the equation of meshing for small teeth difference planetary gearing and a universal equation of conjugated profile are established based on cylindrical pin tooth and given motion. The correct meshing condition, contact line, contact ratio, calculating method for pin tooth's maximum contact point are developed. Investigation on the theory of conjugated meshing is carried out when the tooth difference numbers between pin wheel and cycloidal gear are 1, 2, 3 and ?1, respectively. A general method called enveloping method to generate hypocycloid and epicycloid is put forward. The correct meshing condition for cycloid pin wheel gearing is provided, and the contact line and the contact ratio are also discussed. | CHEN BingKui FANG TingTing LI ChaoYang WANG ShuYan | 2008 | Science China(Technological Sciences)2008，51，5： | 18 |
| 5 | Modification Design Method for an Enveloping Hourglass Worm Gear with Consideration of Machining and Misalignment Errors显示文摘The influences of machining and misalignment errors play a very critical role in the performance of the anti-backlash double-roller enveloping hourglass worm gear(ADEHWG).However,a corresponding efficient method for eliminating or reducing these errors on the tooth profile of the ADEHWG is seldom reported.The gear engagement equation and tooth profile equation for considering six different errors that could arise from the machining and gear misalignment are derived from the theories of differential geometry and gear meshing.Also,the tooth contact analysis(TCA) is used to systematically investigate the influence of the machining and misalignment errors on the contact curves and the tooth profile by means of numerical analysis and three-dimensional solid modeling.The research results show that vertical angular misalignment of the worm wheel(Δβ) has the strongest influences while the tooth angle error(Δα) has the weakest influences on the contact curves and the tooth profile.A novel efficient approach is proposed and used to minimize the effect of the errors in manufacturing by changing the radius of the grinding wheel and the approaching point of contact.The results from the TCA and the experiment demonstrate that this tooth profile design modification method can indeed reduce the machining and misalignment errors.This modification design method is helpful in understanding the manufacturing technology of the ADEHWG. | DENG Xingqiao WANG Jinge HORSTEMEYER Mark F | 2013 | Chinese Journal of Mechanical Engineering2013，26，5： | 16 |

| 11 | Laser-pulsed MIG hybrid welding technology of A6N01S aluminum alloy显示文摘Welding research of A6N01S-T5 aluminum alloy profile for high-speed train was done by using laser-MIG hybrid welding and MIG welding individually. And the weld appearance,welding distortion,mechanical properties of the joints and microstructures were analyzed. The test results demonstrated that high-efficient welding for the profile can be achieved by using laser-MIG hybrid welding,the speed of which can be over 3. 0 m/min. The processing had a good gap bridging ability,even if the gap of the butt joint was up to 2. 0 mm,a good weld appearance can also be got. While the hybrid welding speed was greater than 2. 5 m/min,the welding distortion of the laser-tandem MIG hybrid joints was just about 33% of that of the MIG joints,but the welding efficiency was over 3 times of MIG welding. And tensile strength of the hybrid joints was 85% of that of A6N01S-T5 base metal,9% higher than that of the MIG joints. Fatigue properties was tested individually with pulsed tensile fatigue method in the condition of 1 × 10~7 lifetime. The test results demonstrated that the fatigue strength of the joints was a little lower than that of base material,which could be up to 115 MPa. But the fatigue strength of hybrid welding joints was 107. 5 MPa,which was 23% higher than 87 MPa of MIG welding joints. | 雷振 李小宇 徐富家 汪认 常云峰 | 2017 | China Welding2017，26，4： | 13 |

| 13 | Element geochemistry of weathering profile of dolomitite and its implications for the average chemical composition of the upper-continental crust——Case studies from the Xinpu profile, northern Guizhou Province, China显示文摘Geochemical behavior of chemical elements is studied in a dolomitite weathering profile in upland of karst terrain in northern Guizhou. Two stages can be recognized during the process of in situ weathering of dolomitite: the stage of sedentary accumulation of leaching residue of dolomitite and the stage of chemical weathering evolution of sedentary soil. Ni, Cr, Mo, W and Ti are the least mobile elements with reference to Al. The geochemical behavior of REE is similar to that observed in weathering of other types of rocks. Fractionation of REE is noticed during weathering, and the two layers of REE enrichments are thought to result from downward movement of the weathering front in response to changes in the environment. It is considered that the chemistry of the upper part of the profile, which was more intensively weathered, is representative of the mobile components of the upper curst at the time the dolomitite was formed, while the less weathered lower profile is chemically representative of the | 季宏兵 欧阳自远 王世杰 周德全 | 2000 | Science China Earth Sciences2000，43，1： | 12 |
| 14 | Testing Serial Correlation in Partially Linear Additive Models显示文摘As an extension of partially linear models and additive models, partially linear additive model is useful in statistical modelling. This paper proposes an empirical likelihood based approach for testing serial correlation in this semiparametric model. The proposed test method can test not only zero first-order serial correlation, but also higher-order serial correlation. Under the null hypothesis of no serial correlation, the test statistic is shown to follow asymptotically a chi-square distribution. Furthermore, a simulation study is conducted to illustrate the performance of the proposed method. | Jin YANG Chuan-hua WEI | 2019 | Acta Mathematicae Applicatae Sinica2019，35，2： | 12 |
| 15 | A Study on Retrieving Atmospheric Profiles from EOS/AIRS Observations显示文摘The paper presents the algorithms for retrieving atmospheric temperature and moisture profiles and surface skin temperature from the high-spectral-resolution Atmospheric Infrared Sounder (AIRS) with a statistical technique based on principal component analysis. The synthetic regression coefficients for the statistical retrieval are obtained by using a fast radiative transfer model with atmospheric characteristics taken from a dataset of global radiosondes of atmospheric temperature and moisture profiles. Retrievals are evaluated by comparison with radiosonde observations and European Center of Medium-Range Weather Forecasts (ECMWF) analyses. AIRS retrievals of temperature and moisture are in general agreement with the distributions from ECMWF analysis fields and radiosonde observations, but AIRS depicts more detailed structure due to its high spectral resolution (hence, high vertical spatial resolution). | 官莉 ALLEN Huang 李俊 | 2005 | Acta meteorologica Sinica2005，19，1： | 11 |

| 17 | Herb-partitioned moxibustion alleviates colon injuries in ulcerative colitis rats显示文摘AIM To observe the effect of herb-partitioned moxibustion(HPM) on expression of colonic cytokines in ulcerative colitis(UC) rats.METHODS A UC rat model was established by protein immunization in combination with topical chemical stimulation.Rats in the HPM group(n = 8) received HPM at bilateral Tianshu(ST25) points.The gross injury and pathological scores of the colon were recorded.The expression profile of colonic cytokines was assayed using the protein microarray technique.Specific differential cytokines were selected and verified by ELISA.The corresponding Uni Prot Accessions of the differentially expressed cytokines were retrieved in the Uni Prot database.The pathways involved were analyzed with the help of the KEGG PATHWAY database.The DAVID database was used for functional cluster and pathway analysis.RESULTS HPM improved colon injuries in UC rats,manifested by accelerated repair of ulcers and alleviation of inflammation,and the gross injury and pathological scores both significantly decreased(P < 0.01).Fold change > 1.3 or < 0.77 was taken as the screening standard.There were 77 down-regulated and 9 up-regulated differentially expressed colonic cytokines in the HPM group compared with the model group,and expression of 20 differed significantly(P < 0.05).Twelve of the 20 significantly differentially expressed cytokines [β-catenin,interleukin-1 receptor 6(IL-1 R6),IL-1β,B7-1,nerve growth factor receptor,AMP-activated protein kinase-α1,neuropilin-2,orexin A,adipocyte differentiation-related protein,IL-2,Fas and Fas L] were up-regulated in the model group(n = 3,compared with the normal group) but downregulated in the HPM group(n = 3,compared with the model group).Functional cluster analysis showed that the differentially expressed colonic cytokines in the HPM group regulated apoptosis and protein phosphorylation.KEGG pathway analysis showed that 52 down-regulated and 7 up-regulated differentially expressed colonic cytokines in the HPM group had pathways.The pathways that interacted between the cytokines and their receptors accounted for the largest proportion(28 of the downregulated and 5 of the up-regulated cytokines).CONCLUSION HPM promotes the repair of colon injuries in UC rats,which is related to the regulation of several abnormally expressed cytokines. | Dan Zhang Yan-Bo Ren Kai Wei Jue Hong Yan-Ting Yang Li-Jie Wu Ji Zhang Zheng Shi Huan-Gan Wu Xiao-Peng Ma | 2018 | World Journal of Gastroenterology2018，24，30： | 11 |

| 19 | Heavy metals contents in soil profiles of typical agricultural lands in Yixing,Jiangsu Province,China显示文摘The effect of land use pattern on the heavy metals(HMs)distribution in soil profiles was investigated in Yixing City,China,for the four typical types of land utilization,i.e.vegetable fields on the plain,paddy fields,tea gardens on hilly lands and bamboo groves.The variance of HMs concentration in the depth of 0-15 cm,15-30 cm,30-60 cm of soil profiles was compared among the different tillage ages. Results showed there was a notable accumulation of Cd,Hg,Cu,Pb,Zn and Cr in the soil profiles of vegetable fields and paddy fields causing a pollution of Cu,Hg and Cd in some profiles,while no remarkable accumulation of HMs in the soil profiles of the tea gardens and bamboo groves was found. The accumulation extent of HMs in the soil profiles of the four kinds of land use followed a sequence of vegetable fields>paddy fields>tea gardens>bamboo groves.The accumulation of HMs was mainly due to the industry,transportation,other urban human activities,and intensive use of fertilizers and pesticides.The downward leaching of HMs was relatively remarkable in the soil profiles of vegetable fields. There was an accumulation in surface and subsurface layers for Cd,Hg,Pb,Zn in the soil profiles of paddy fields and tea gardens,and for Cd,Hg in those of bamboo groves.Serious pollution effects of Hg, Pb,and Zn have been shown in the soil of vegetable fields.All the four kinds of agricultural land are basically free from the pollution of the external sources of As and Ni.With the increase of tillage time, the soil of vegetable and paddy fields will face the potential risk of HMs pollution,which mainly comes from Hg,Cd and Cu,whereas that of tea gardens and bamboo groves faces a relatively small risk. | Zhou ShengLu Liao FuQiang Wu ShaoHua Zhang HongFu Ren Kui | 2008 | Chinese Science Bulletin2008，53，S1： | 11 |
