thermal-protective shell

Turbulent stress also Causes the thermonuclear reaction of the He burning shell in AGB star not to be un-stable, and the occurrence of the thermal pulse greatly ahead of time, and very frequent.

使AGB星氦壳层热核反应更加不稳定，热脉动的发生大大提前了，而且更加频繁。

Bimetallic shallow spherical shell is an important elastic element for thermal sensitivity in precision instrument.

在精密仪器热敏弹性元件中，双层金属中心开孔扁球壳占有很重要的地位。

A corresponding computer program by using finite element methed is coded in FORTRAN 77 and is implemented on microcomputers. Numerical results show that the thermal stress and material softening irradiated laser beam will induce the catastrophic buckling failure of the pre compressed cylindrical shell.

数值计算结果表明，激光照射区域产生的热应力和材料软化将导致处于正常工作状态的轴压圆柱壳发生灾难性的热屈曲破坏。

The finite element code LS_DYNA is used to investigate the response of the axisymmetry cylindrical shell under the thermal impact, and the curves of displacement vs time and that of stress vs time are obtained.

最后利用有限元程序LS-DYNA对轴对称圆柱壳受高速热冲击作用进行了计算机仿真分析，得到了位移时间曲线和单元的应力时间曲线，同文献已有的结果吻合的较好。

The shell of the device design the thermal insulation layer, the system of the heat loss is reduced, further improve the conversion efficiency of field device.

在装置的外壳设计了保温层，使系统的热损耗降低，进一步提高了装置的光热转换效率。
