摘　　要：目前获取高压传感器动态特性的通用方法是动态校准。由于校准设备的特性,对获取的动态特性存在限制。受设备振动模式和校准过程中传压管道的影响,动态特性的信息在某些频带不能充分表达。该文通过在不同的设备上校准相同的传感器获得相应的数据,对数据进行谱峰和相关谱分析,得到了一些有价值的结论。At present, it is a general method that is to obtain dynamic characteristic of high-pressure transducer using dynamic calibrating methods. There are limitations in characteristic of transducer obtained because of feature of the calibrating device. So the information in some frequency - band is not shown fully and it is affected by vibration mode of the device and stress wave created while calibrating process. The data are gotten by calibrating the same transducer on two devices. The spectrum peaks and correlation spectrum are analyzed. The valuable results are given out.
