中文翻译成英文啊,急!谢帮忙翻译啊,谢谢：1.冷热循环测试2.100度条件下放置2h,再-20度条件下放置2h,连续循环3天,样品应无裂纹.3.测试后样品无裂纹.

觉得一楼的译得好些.二楼也是高手啊,学习中

Test on temperature circle
Under 100C, 2h is a must; under 100C plus 20C, 2h is a must too; do so like the above for 3 days before the sample should be no crack or fracture.
Through a series of experiments, the sample has no crack or fracture absolutely.

1.The cold heat tests circularly
Under 2.100 degrees condition place a 2 hs, again-under 20 degrees condition place a 2 hs, circulate for 3 days in a row, the sample should have no crack.
3.The sample has no crack after testing.

1.Cold hot circulation test.
2.Under 100 conditions lays aside 2h, again under -20 condition laysaside 2h, continuously circulates 3 day, the sample should not havethe crack.
3.After the test the sample does not have the crack.

1.Temperature cycle testing 2.100 degrees conditions placed 2h,and then placed under the conditions of -20 degrees 2h,continuous cycle of three days,samples should be no cracks.3.After testing samples...
