Wheat is one of the main cereal crops in China. Evidently, the fluctuations of the production and the price of the grain in the world have a direct influence on the grain production and the national economy and the people’s livelihood in China. It is, therefore, urgently needed to predict the wheat yield at an early date. At present, most of the administrations concerned make the prediction of wheat yield near or after the har-

Emergence of multidrug-resistant tuberculosis (MDR-TB) urgently demands for simple, rapid and inexpensive methods of its detection for the effective treatment of drug resistant tuberculosis, particularly in low-income countries. A total of 113 clinical isolates of M. tuberculosis were tested for four first line antitubercular drugs by nitrate reductase assay (NRA) and were compared with standard proportion method to evaluate NRA efficacy. Results were available in 7 - 14 days by NRA as compared to proportion method which generally takes 4 - 6 weeks. The sensitivity and specificity of NRA were 98.1% and 100% for isoniazid, 95.1% and 98.6% for rifampicin, 91.4% and 94.9% for streptomycin, and 78.6% and 97.9% for ethambutol, respectively. Agreement between NRA and proportion method were 99.1%, 97.3%, 93.8%, 95.6% for isoniazid, rifampicin, streptomycin and ethambutol, respectively. NRA is easier, inexpensive and reliable method for susceptibility testing of Mycobacterum tuberculosis for isoniazid and rifampicin, the two most im- portant drugs for the treatment of tuberculosis. The reduction in susceptibility testing time, and higher sensitivity and specificity of NRA method is of fundamental importance in detecting MDR-TB.

基于(w,z)参数化轴对称Three Dimensions(3D)摆的姿态控制问题研究,提出(w,z)参数描述姿态描述方法。该方法通过2次绕正交轴旋转,引入复变量,将球面上的点向复平面投影。提出proportion Differentiation(pd)控制对轴对称3D摆的姿态控制方法。首先列出轴对称3D摆的动力学方程,以(w,z)参数表示轴对称3D摆的姿态运动学方程及推导过程。利用(w,z)参数设计出PD控制器,使得轴对称3D刚体摆在其倒立位置渐近稳定。仿真实验验证了控制器对轴称3D摆姿态控制的有效。
