| 1 | Analytical potential energy function for the ground state(~1A_1) of hydrogen isotopic D_2O molecule显示文摘The present work is to construct the potential energy function of isotopic molecules. The so-called molecular potential energy function is the electronic energy function under Born-Oppenheimer approximation,in which the nuclear motions(translational,rotational and vibration motions) are not included,therefore,its nuclear vibration motion and isotopic effect need to be considered. Based on group theory and atomic and molecular reactive statics(AMRS),the reasonable dissociation limits of D2O(1A1)are determined,its equilibrium geometry and dissociation energy are calculated by density-functional theory(DFT) B3lyp,and then,using the many-body expansion method the potential energy function of D2O(1A1) is obtained for the first time. The potential contours are drawn,in which it is found that the reactive channel D + OD→D2O has no threshold energy,so it is a free radical reaction. But the reactive channel O + DD→D2O has a saddle point. The study of collision for D2O(1A1) is under way. | RUAN Wen1,2,LUO WenLang1,ZHANG Li1 & ZHU ZhengHe1 1 Institute of Atomic and Molecular Physics,Sichuan University,Chengdu 610065,China 2 College of Mathematics and Physics,Jinggangshan University,Ji’an 343009,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009,52,4: | 2 |
| 2 | Synthesis and Structural Characterization of new Tri(2-methyl-2-phenylpropyl)tin Carboxylates containing Germanium显示文摘Eight tri(2-methyl-2- phenylpropyl) germylpropionates have been synthesized. and their structures were characterized by elemental analysis, IR. multinuclear NMR(1H. 13C.119 Sn) and MS. The spectroscopic studies revealed that compounds of this type possess a tetrahedral geometry, which have been expected to have good biological activity. | Xue Qing SONG Xiao Niu FANG Qing Lan XIE Jing LI (Key Laboratory of Elemento- organic Chemistry.

| 4 | The Fall of the Monument——William Faulkner and His A Rose for Emily显示文摘This article first introduces Faunlkners Yaknapatawpha serial, a myt hical kingdom created by Faulkner in most of his major works, and Faulkners ma in concerns in his writing. Then, A Rose for Emily,one of the serial, is apprec iated to show some of Faulkners artistic preoccupations. The article presents that Faulkner exposes, in this short novel, the conflicts between the old tradit ion and the new order in the South and the disillusionment of the southern desce ndants in the conflicts. | LIU Xiao-Juan KANG Xu-Ping(English Department, Jinggangshan TeachersCollege, Jian, JiangXi 343009) | 2002 | 井冈山大学学报(社会科学版)2002,23,3: | 1 |
| 5 | Factors Affecting the Income of Farmers显示文摘Based on the introduction of factors affecting the income level of farmers in China,a total of 31 provinces,autonomous regions and municipality cities are taken as samples to select 13 factors affecting the income level of farmers,which are arable land area(X1),disaster area(X2),effective irrigation area(X3),fertilizer application(X4),mobile phone(X5),personal computer(X6),people joining in the new rural cooperative medical care(X7),rural investment(X8),household-use machine(X9),agricultural product price(X10),proportion of labor force with above junior high school education(X11),rural delivery route(X12),and rural electricity consumption(X13).At the same time,factor analysis method is used to analyze the factors affecting the income level of farmers.Result shows that common factors affecting the income of farmers are the agricultural production factor F1,the expanded reproduction factor F2,the information use factor F3,and the output reduction factor F4.At present,education degree of farmers and ability of farmers in grasping information have relatively great impact on the income of farmers,and can effectively promote the income growth of farmers.Scores of F1 in Henan,Shandong and Hebei are generally higher;Jiangsu,Guangdong,Zhejiang and Shandong Provinces have relatively high scores of F2;Shanghai,Beijing and Guangdong have relatively high scores of F3;and Hunan,Hubei and Xinjiang have relatively high scores of F4.Finally,countermeasures are put forward to improve the income of farmers based on empirical study. | XIONG Zhang-lin1,NIU Ying2 1.College of Business,Jinggangshan University,Jian 343009,China 2.Statistical Bureau of Jian City,Jian 343000,China | 2010 | Asian Agricultural Research2010,2,5: | 0 |
| 6 | Major Problems and Countermeasures of Foreign Trade in China under the Background of Expanding Domestic Demand显示文摘Starting from China's macro-economic policy level and combining with the status of foreign trade in China, major problems in the development of foreign trade are analyzed under the background of expanding domestic demand, which is guided by the macro-economy, international finance, international trade and other related disciplines. Problems are mainly the inflation, the reduction of import, the trade protection, the increase in export costs, the reduction of export, the scale shrinkage of foreign trade, the speculation of short-term hot money, and the increase in risk of economic fluctuation. Finally, corresponding countermeasures are put forward, such as actively coping with the appreciation of the RMB, effectively increasing the anti-risk ability of RMB, firmly maintaining the currency stability of RMB, reducing the international trade friction, transforming the growth model of foreign trade, promoting the industrial and products upgrading of foreign trade, enhancing the benefits of foreign trade, forming an effective price competition mechanism, increasing the support in trade, improving the environment for trade development, correctly dealing with the relationship between government and foreign trade enterprise, controlling inflation, and restricting hot money speculation. | RUAN Wei-tong, LI Yu-hong Business School, Jinggangshan University, Ji’an 343009, China | 2010 | Asian Agricultural Research2010,2,12: | 0 |
| 7 | Mathematical Modeling of the Numerical Control Cam Grinder Wheel Center Displacement and Its Application显示文摘Considering grinding a cam with numerical control(NC)cam grinder,a mathematical model should be estab- lished with the unified parameter based on the original cam-lobe lift data to describe the movement of wheel and establish the relation between the wheel center coordinate,the measuring angle and workpiece’s spindle rotation angle.By analyzing,the grinding wheel can be regarded as different followers.To the planar and roller followers,different mathematical models are established, but they can be unified in Eqs.(17)of this paper with the different value of the roller radius r1.And also the model is suit for the edged follower when assuming the roller radius r1=0.Experimental verification was done with TKM120 CNC/CBN grinder with NC sets’ interpolation according to the model,which shows that high precision parts can be manufactured and this mathemat- ical model can be practically applied for NC cam grinder. | WANG Xiaojun LIU Zhaohui College of Industry,Jinggangshan Institute,Ji’an 343009,China, | 2006 | 武汉理工大学学报2006,28,S3: | 0 |
| 8 | Sonoluminescence of luminol-sodium carbonate solution显示文摘The authors have taken the photo of a prcsct paper-cut figure with ordinary film exposed to the sonoluminescence of aqueous solution of luminol-sodium carbonate, and also obtained the sonoluminescence spectrum and photo-fluorescence spectrum of this solution. These results show that the wavelengths of the enhanced sonoluminescence by luminol in this solution are mainly in the visible region. In respect to the cmission wavelengths, there is a certain equivalency between the sonoexcitation and photoexcitation. | LI Huamao(Dep. of Physics.
