The testing was done on the working conditions such as the sample resolution, element wave-length, air-carrier flow, auxiliary air flow, observed altitude, etc.

对样品的溶解、元素波长、载气流量、辅助气流、观察高度等工作条件进行试验，选定了最佳测定条件。

It is present a method to design altitude control system for a high altitude airship using auxiliary ballonet charge or deflation and elevator combination control.

当时高度存在大误差时，采用副气囊和空气舵组合控制改变飞艇的姿态实现快速爬升或下降；
