The fragment velocity depends on local thicknessofshell, the thicker or the heavier is the local shell, and the bigger the influence of shell on shock wave intensity is.
破片速度与壳体厚度有关，壳体越厚或质量越大，对空气冲击波强度的影响越显著。

The design and calculation of mostly parts are carried out specifically, which includes of power of heater, element of heater, thicknessofshell, vacuum system, and drive etc.
设备的设计计算主要包括加热器的功率、加热元件、壳体的壁厚、真空系统、传动等方面的计算。
