错误信息（2个）：
*** ERROR *** CP = 20.781 TIME= 21:04:58
For material 1 at temperature 0, the initial slope of the stress-strain
curve based on the TB,MISO table ( 2.160687961E+11 ) is less than EX (
2.2E+11 ).
*** ERROR *** CP = 20.922 TIME= 21:05:00
The step data was checked and there were errors found.
Please check output or errors file ( D:\My Documents\huitan.err ) for

麻烦大家了！谢谢！ 把mp,ex,1,220e9中的220e9改成216e9就可以了
