部分仪器中应用了液体阻尼器,但是对液体阻尼器性质的了解多重于实验,理论上分析计算较少。本文对仪器中为什么要采用阻尼器以及液体阻尼器的原理不再叙述,仅对液体阻尼度的计算及液体阻尼器特性作些探讨。目前所研制的一些仪器,尤其加速度计中的液体阻尼器多采用活塞式和毛细管式,故住下面讨论 Some of the instruments used in the liquid damper, but the nature of the liquid damper to understand more than the experiment, in theory, less calculated. This paper explains why the principle of damper and liquid damper should not be mentioned in the instrument, and only discusses the calculation of liquid damping and the characteristics of liquid damper. Currently developed some of the instruments, in particular accelerometer liquid damper more use of piston and capillary type, so live to discuss the following
