The conception of bursting disk's ultimate elasticity prussure in normal temperature was advanced for the pressure vessel installed with bursting disk to ensure that the gas leak test could be carried out successfully and the bursting disk would have the correct property in the procedure of it using. 为保证气密性试验顺利进行和爆破片在使用中具有正常性能,对安装爆破片的压力容器提出了爆破片常温弹性极限压力的概念。
