基于目前准静压计算公式的局限性，提出了一个通用计算公式，并提供了未知参数的确定方法。通过该方法在一个容积为500L的密闭爆炸罐中，用PCB压电式压力传感器测试了35g、80g和100gTNT样品的准静压，并拟合了TNT样品的准静压计算公式。利用该公式计算了55g和90gTNT的准静压，并与试验值进行对比，两者符合较好，说明提出的参数拟合方法是可行的。

Based on the limitation of quasi-static pressure calculation formulas at present, a formula in common use was proposed, and a determination method of unknown parameters was provided. Through the proposed method, the quasi-static pressures of 35g, 80g and 100g TNT sample were tested in a 500L confined chamber, by piezoelectricity pressure sensor, which was made by PCB corporation, then the quasi-static pressure calculation formula of TNT was fitted. Using the formula, the quasi-static pressures of 55g TNT and 90g TNT were calculated and compared to the test value. Two results agreed well, it indicated the determination method of unknown parameters in this paper is proper.
