A glass tube a few feet long is closed at one end with glass and at the other with a flexible diaphragm. 它是一个几英尺长的玻璃管,一端用玻璃封闭,另一端用柔性隔膜封闭。
The geometrical shock dynamics was used for the theoretical analysis to the shock wave and unsteady boundary layer interaction, and a double driver shock tube with rarefaction waves bursting diaphragm was used for the experimental investigation. 本文对这种现象用激波动力学理论进行分析,并把这种干扰现象看成激波的绕射现象,同时在稀疏波破膜的双驱动激波管中进行实验观察。最后把理论分析与实验观察进行了比较。
Some measures were put forword to improve the detecting sensitivity, such as choosing the photo-electricity tube with linked rectangle, high frequency response, low noise as detection parts and applying adjustable diaphragm, multi-adjustable comparison voltage. 提出选择拼接长条形、具有高频响应、低噪声的光电接收管作为探测器件,采用可调光阑、多路可调比较电压、提高电路放大倍数的措施,可以提高天幕靶的探测灵敏度。
On the condition of tube mill with inclined diaphragm isn ′ t axial displacement 倾斜隔仓板磨机筒体无纵向位移的条件
The research on the joints between the concrete filled square steel tube columns and H shape steel beams mainly focus on the inner diaphragm Joints at present, and the weld steel tube columns are generally used. 目前,对方钢管混凝土柱与钢梁刚性连接节点的研究主要是针对内隔板式节点,柱多为焊接方钢管。
Modification was done on the shock tube in which the electro-heating diaphragm bursting device was involved to increase the repeatability of shots and decrease the deviation of shock speed. 对激波管进行了改造,采用电控破膜可明显提高实验重复性,减小了运动激波速度偏差。
