介绍了该类轧辊的温度、应力状态、临界裂纹尺寸及内部质量情况。
The temperature field, stress, critical crack size as well as the interior quality of the rolls are presented.
由此确定了不同材料在不同环境溶液中的临界裂纹尺寸，得到了气瓶工作压力及等效应力与临界裂纹尺寸的关系曲线。
The critical crack sizes of different materials in H_2S environment were thus figured out, and the curves with working pressures and equivalent stress to critical crack size were plotted.
结果还表明，随着夹杂物尺寸的增加，裂纹临界形核应变降低。
It is also showed that the critical strain values of crack nucleation decrease with the increase of the size of inclusions.
