Parsimonious Covering Probability Model for Turbogenerator Vibration Faulty Diagnosis     

ZHANG Bi de  SUN Cai xin  OU Jian  HU Xue song 《保鲜与加工》2002,(5):101-103107

The turbogenerator vibration faults have the character of variety. Many faults often occur synchronously. This paper introduces a diagnosing model based on parsimonious covering theory and probability. A model for turtogenerator's fault diagnosis is proposed. The availability of this method is proved by two fault diagnosis examples of turbogenerator. The results show that the model proposed can be used for multi_fault diagnosis together. It may make up shortage for some of expert systems and neural networks in some aspect. From the practice,this model has higher reliability and practicability.  相似文献   

Optimum Planting System for Energy Saving and Healthy Demanded     

BAI Xue lian 《保鲜与加工》2002,(8):77

It is proved that planting is effective to improve environment both indoor and outdoor resulted from the functions of plants to clean air and save energy. So the contradiction between saving energy and comfort,healthy demanded by people can be solved by planting. The planting have being emphasized and expanded during recent years,but in the planting plan,just the function of beautifying the environment is concerned and the function of ecological and saving energy are neglected. The analysis on the ooptimum system of planting is to make the planting system as an organic composition in the effectiveness structure and space layout of the city. Based on the study on equivalent relation of different effects on environment, the optimum system of planting structure will be determined in order to achieve the integrated effects of planting on environment.  相似文献

黄淮夏大豆形态性状的遗传研究     

贺春林  薛应离 《华北农学报》1991,6(2):25-29

本文以黄淮地区6个夏大豆品种(系)通过双列杂交保留下来的F_3代材料,研究大豆6个形态性状的遗传特性.结果表明,株高、有效分枝数、主茎节数、主茎荚丛数和茎粗5个性状均符合加性—显性模型.而底荚高则存在非等位基因之间的互作效应.株高、有效分枝数、主茎节数和主茎荚丛数为部分显性,茎粗存在超显性现象.主茎节数和主茎荚丛数可能有相似的遗传特点.豫豆8号大豆带有较多的控制株高的显性基因,油84-30大豆带有较多的控制分枝和茎粗的显性基因,而尖顶大白角大豆控制主茎节数和美丛数的显性基因较多.  相似文献

感应电机矢量控制解耦算法的研究     

赵文祥  吉敬华  郑宏  白雪  黄振跃 《农机化研究》2006,(2):51-52

矢量控制是通过坐标变换将感应电机模型转化为类似于直流电机的模型,使定子电流在同步旋转坐标系中的两个相互垂直分量分别独立控制转矩和转子磁链,从而获得类似于直流电机的调速性能。为此,对感应电机的数学模型进行了分析,通过矢量变换得到了在d、q坐标系下的闭环系统方程,对电机进行了解耦控制。在由TMS320F2812搭建的数字化实验平台上进行了实验,实验结果证明了研究方案的可行性。  相似文献
