The result of transient state analysis indicated the thermal-mechanical effect on seal face during loading, the seal surface parameter dropped steadily during unloading.
理想瞬态分析实例表明，加载过程中密封端面产生热机效应，稳定减载过程中端面参数平稳下降。
It expounds that the key of solving thermal transient sealing problem is to obtain the thermal increment of stud-bolt loading.
阐明了热瞬态密封问题求解的关键是给出螺栓载荷的热态增量；
