准确地测量冲击波是研究冲击波传播规律的关键。冲击波参数的测试,一般都要求多点同时进行。由于压力变化范围大,现场试验又必须遥测,因此要求测量系统有很宽的量程;压力讯号经数百米电缆传输后不能畸变,而常用的各类测压系统都很难满足上述要求。且测试前都需要进行标定(采用油压静标和激波管准动标方法),其标定压力讯 Accurately measuring shock wave is the key to studying the law of shock wave propagation. Shockwave parameters of the test, generally require more simultaneous. Due to the wide range of pressure changes, the field test must be telemetered, thus requiring a wide measuring range of the measuring system. The pressure signal can not be distorted after being transmitted through the hundreds of meters of cables, and the commonly used various types of pressure measuring systems are difficult to meet the above requirements. And before the test needs to be calibrated (using hydraulic static and shock tube quasi-standard method), the calibration pressure information
