持久性

Besides, the development and perfection of O-R MAPPING technology can ensure developing reliable, stuggy and efficient applications when applications access the rock-bottom database.

与此同时，对象-关系映射数据持久发展与完善为建立可靠、健壮、高效应用程序提供了保证。

Transformation mechanism of carbides and their effect on the stress rupture property were investigated in a Ni-base single crystal superalloy with microcontent of carbon.

研究了一种含微量(0.015%)碳镍基晶高温合金在热处理和持久过程中碳化物演化机制以及各种碳化物对合金持久能。
