These studies indicate the rationality of our molecular design based on the crystal structure of KARI complex. To obtain more KARI inhibitors with high activities, the molecular docking and 3D-QSAR methods were applied to our further studying of these amidine compounds. Two methods AutoDock3. 0.3 and DOCK4. 0 were used in molecular docking, and the calculate results accord with that of herbicidal tests in general. The CoMFA model from 3D-QSAR analysis provided useful guidance for designing highly active compounds prior to their synthesis.

In the dissertation, we presented a method to calculate the start oscillation length and real starting asynchronous velocity parameter. In the meantime, when the effect of two or more azimuthally asymmetric space harmonics in the high power broadband helix TWT on the start oscillation length and real starting asynchronous velocity parameter were also analyzed.

数值计算表明：增大渐变的强度，就可以增加起振长度，而且当渐变的强度增大到一定值时就不会产生返波振荡；当衰减器靠近输入段时，起振长度就随之减小；当增大衰减器的长度或减小衰减量时，相对起振电流随之减小，可见衰减器对起振条件确实有明显的影响。

Based on the definition of desertification from the United Nations Convention to Combat Desertification,the potential extent of desertification in China was revised by employing Thornthweite＇s and Penman＇s formulae to calculate humidity index using the records of 671 meteorological stations from 1950 to 1990,and the biogeographical features of the climate types were clarified.
