Based on requirements of cotton HVI(high volume instrument)testing psychometric room, presents an idea of constant temperature and humidity system design and separate setting and control.

根据棉花HVI检验恒温恒湿环境室的要求,提出了恒温恒湿系统方案及温湿度分体设置和单路分控的设计思想。

By investigating the mechanism of camera imaging process in star field,several aspects of an imaging system,such as the optic system,sensor characteristics and aperture diffraction process,were modeled.

在分析星空环境下相机成像机理的基础上,从相机光学系统,光感受器工作特性和光圈衍射过程三个方面对星空环境下的成像系统进行了建模。
