Asian Agricultural Research 2012年第6期4卷 1-4页

作者： HUANG Qing-hua NIU Lei WEI Xiao-ya XIE Lin-sha College of Economics and Management Southwest University Chongqing 400715 China

We use the secondary relative benefit model based on DEA to evaluate the performance of agricultural financial expenditure in Guizhou Province, which can give due consideration to the production effectiveness determined by objective natural conditions, and management effectiveness of all regions (as decision-making body) in the use of financial fund for supporting agriculture. In general, there is north-south gradient difference in the performance of financial support for agriculture between regions in Guizhou Province. The drought in 2010 has significant impact on the technical efficiency in the whole province; the performance score of each item in Liupanshui City and Southwest Guizhou is very low; the technical efficiency and management efficiency in most regions need to be improved. In order to improve the performance of financial support for agriculture, we need to ensure the scale of input; at the same time, provide appropriate preferential financial policies for agricultural infrastructure, especially the construction of rural water conservancy, development and promotion of agricultural science and technology, and other fields; adopt the way of special check and acceptance of supporting projects to strengthen the use management of the fund for agriculture.

The detection mission of gravitational waves in space is that the accuracy of the long-baseline intersatellite laser interferometry on the million-kilometer order needs to reach the order of 8 pm/*** all noise sources that affect the interferometry accuracy,tilt-to-length(TTL)coupling noise is the second largest source of noise after shot *** paper focuses on studying the contribution of TTL coupling noise of the telescope system in the intersatellite scientific *** referring to the laser interferometer space antenna(LISA)’s noise budget,TTL coupling noise is required to be within±25μm/rad(±300μrad).Therefore,this paper focuses on studying both the mechanism of TTL coupling noise due to the noise sources of the telescope and the method of suppressing the TTL noise,which can lay a foundation for noise distribution and the development of engineering prototypes in subsequent tasks.

为了精确计算三维静电场中球形电极表面的电场强度,提出了基于球坐标变换的球面曲边三角形边界元法。该方法中积分的区域为球面,求解函数采用球面上球坐标线性插值,单元的外法线方向为严格的球面法线方向。计算结果表明,与平面直边单元相比,在网格剖分节点相同时,球面曲边三角形边界元法的计算精度明显提高。在计算精度要求相同时,球面曲边三角形边界元法节点数较少,具有计算速度快,占用计算机内存少等优点。
