由于水介质和空气介质的差异,使得在水中测压较之空气中有着较大的区别。论述了一种新型的应用于水下的自制应变式传感器的工作原理,在理论上解决了水下枪械膛压测试的技术难点,并给出了应用实例,分析了实验现象,得到了满意的实验结果。

Abstract :Because of the differences between water and air , there are some differences betweenpressure measure2 ment in the water and that in the air. Operation principle of one new type of strain sensor that was designed es2 pecially to use in under water pressure measurement is introduced ,technical difficulties of pressure measurement under water are also solved theoretically ,and application examples are given. The result of experiment is satisfac2
