[Objective] The aim was to study the heat stress mechanism of differen tially expressed genes in rat jejunal mucosal.[Method] Variable cluster analysis and cluster analysis of samples on the differentially expressed heat stress genes in rat jejunal mucosal were carried out with SAS software,and statistics of distribution of the differentially expressed genes on chromosomes were conducted.[Result] The differentially expressed genes were divided into seven categories,of which,the upregulated genes included three categories （i.e.：Category A：Hspa1a,Hspa1b,Hspb1,Hsph1,Dnaja4,Ahsa2 and P4ha1; Category B：Cyp1a2,Zbtb16,Gucy2g,Fgb,Cyp4a3 and Etv2; and Category C：Cyp1a2,Chac1 and Cyp4b1） and the down-regulated genes included four categories （i.e.：Category D：Tlr2,Noxo1,LOC286989 and Aspg; Category E：RGD1560395,Alb and BQ194726; Category F：Ccl4,Gzmk,Al228153,Anxa10,S100a9 and Ascl5; and Category G：Reg1a and Slc13a1）.The classification,function and reasons of differential expression for each gene category were analyzed.[Conclusion] Most of the three categories of up-regulated genes were related to the heat shock proteins; and most of the four categories of down-regulated genes were related to the immunity,providing reference for discussion of the heat stress mechanism.

中国在中亚:政策的演变

俄罗斯东欧中亚研究 2007年第6期 63-72页

作者：柳丰华北京大学国际关系学院

中亚国家独立以来,中国对中亚的政策经历了三个阶段的演变:建立睦邻友好关系(1991年12月～1997年9月)、加强能源、经贸和安全合作(1997年9月～2001年6月)、在双边和上海合作组织框架下发展全方位合作关系(2001年6月至今)。中国已经与中... 详细信息

中亚国家独立以来,中国对中亚的政策经历了三个阶段的演变:建立睦邻友好关系(1991年12月～1997年9月)、加强能源、经贸和安全合作(1997年9月～2001年6月)、在双边和上海合作组织框架下发展全方位合作关系(2001年6月至今)。中国已经与中亚国家建立起密切的政治、经济、安全合作关系,已经成为中亚地缘政治的主要角色之一。中国对中亚政策仍旧存在工具不足——限于经济合作和一定程度的安全合作——的弱点,且受到美国、俄罗斯、中亚国家政局和政策等因素的影响。中国与中亚国家关系前景美好。

China-Russia Comprehensive Strategic Partnership： Formation, Features, and Prospects

第40届中国控制会议

作者： Longfei Ma Hsiucheng Wang fenghua liu Kaiyuan Li School of Telecommunications Engineering Xidian University

The Unmanned Surface Vessel（USV） is a type of driverless and intelligent vessel capable of automatic *** can perform the extremely dangerous tasks that humans cannot complete. Through a method that combines classification and learning, we have built a remote monitoring system for USV. This system uses the Chebyshev fitting algorithm to process the data features of the UAV working states by preprocessing the telemetry data. Feature vectors substitute the original data. Based on reinforcement learning and PSO-improved SVM, state analysis of the USV is implemented in the Microsoft Foundation Classes（MFC） environment. By comparing with other algorithms, the performance of the designed system verifies its effectiveness, and at the end of this paper, we also discussed the limitations of the algorithm.

China International Studies 2016年第4期36卷 61-75页

作者： liu fenghua Institute of Russian Eastern European and Central Asian StudiesChinese Academy of Social Sciences

The year 2016 marks the 20th anniversary of the China-Russia comprehensive strategic partnership （hereinafter referred to as ＂the strategic partnership＂）. Over the past two decades, China and Russia have made consistent efforts to enrich and deepen this new type of state-to- state relations. On the occasion of commemorating this important diplomatic event, it is timely to review the development of this strategic partnership over the past two decades and to look at its future prospects.

第十五届全国化学动力学会议

The OH laser induced fluorescence method was used to study the kinetics of CHOO with SO,(HO), CHI and I atoms. Decay of CHOO is not strictly first-order since its self-reaction is rapid.[1]-[4] With this consideration, we derived the rate coefficient of CHOO + SO/(H2 O)2/CHI/I taking into account the contribution of CHOO self-reaction. For the CHOO + SO reacton, the rate coefficient is measured to be(3.88 ± 0.13) × 10 cm molecule s at 10 torr, which agrees very well with a previously reported value obtained by directly monitoring CHOO using the UV absorption method with CHOO self-reaction considered.[1] We did not observe obvious evidence of SO catalysed CHOO isomerization or intersystem crossing effect in this reaction. CHOO +(HO) is supposed to count for major sink of CHOO in the atmosphere, but previous rate coefficient measurements were not in good consistency. We have revisited this reaction including the self-reaction of CHOO and obtained the rate coefficient to be(7.53 ± 0.38) × 10 cm molecule s at 60 torr and 300 K. The rate coefficients of CHOO + CHI and CHOO + I were measured to be(5.2 ± 2.6) × 10 and(2.2 ± 1.1) × 10 cm molecule s respectively.
