The operational condition of the Cartesian diver typeof manostat and the dependence of pressure stability on tempreture have beenstudied.

基于浮子稳压器的低压流气系统有制作简单，使用方便等优点，本文通过一些实验以及实验和理论估计的对比找出了提高流气系统工作气压稳定度的一些条件，为制造高稳定度流气系统提供了一点经验。

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.

通过对副高的描述、形成及演变特征和物理机理的研究进行回顾，认为：副高是相对的气压的高值，是由于平均经圈环流的存在，使得有空气质量在副热带地区的堆积而形成的，成为带状，表现出在经度方向的不均匀，这是一种纬向平均的观点；同时，在这个平均的高压带上常常有闭合的单体存在，表现出纬向的不均匀。

Based on the noise theory and experi mentation ,the author founded the onli ne method to test current noise , validated the relation bet ween te mperature ,aperture and pressure with current noise .This paper firstly analyzed gener— ati ng mechanis mof discharge niose ,studied the measure and factor of discharge niose ,i ndicated an effective method for degradi ng the discharge noise ,which pro moted the performance of laser gyro fro m0.01°／h to 0.001°／h.

文中以氦氖气体激光器的噪声特性理论为指导，以试验研究为基础，建立了在线噪声电流测试方法，通过试验验证了温度、腔体毛细孔径、谐振腔充气气压等参数与放电噪声的关系，首次提出了放电噪声产生的机理，分析了电流噪声的检测方法及影响因素，给出了减小和抑制放电噪声的有效方法，使得激光陀螺的性能由0.01°／h 提高到0.001°／h。
