The time history of angular rate includes three stages which are rocket moving in tube, exhausted flow impacting and free vibration after impacting. 其时间历程包括发射时弹体在管内运行、燃气对定向器束冲击及冲击后定向器束自由振动的振动角速率。
Based on a general flow equation for the variable area flowmeter& the capacitive angular position transducer, this paper describes a new type of smart metal tube variable area flowmeter which has realized a high accurate measurement. 基于浮子流量计普遍流量方程[1]及电容角位移式传感器检测机理的新型智能金属管浮子流量计,实现了对流量的精确测量。
The angular distribution of total radiation falling on a tube with flat plate reflector was analyzed. 用解析方法对带平面反射板的单根太阳真空集热管表面辐射流分布进行了分析,并得出了相应的结果。
