提出了在高温介质条件下，泵的法兰接头的螺栓计算技术．应用了马里宁（Ｍａｌｉｎｉｎ）流动理论，得出了一种关系，可用以确定预定时间内零件中的应力下降值或在特写时间内降至一定值的初始应力；这种关系也可用以确定延迟力（初始应力）降至预定值的时间．并提供了一些数值算例．
Proposed in the high temperature medium conditions, the flange of the pump bolt calculation technology. Applying Malinin’s flow theory, a relationship has been drawn that can be used to determine the stress drop in a part within a predetermined time or the initial stress that drops to a certain value during a close-up time; this relationship can also be used to determine the delay The time when the force (initial stress) drops to a predetermined value. And provides some numerical examples.
