求翻译：采用显微维氏硬度测量法对焊补前后试样的显微硬度进行了测量，测量结果表明出焊补前后试样的硬度无变化，一次焊补未改变试样的硬度。是什么意思？

The micro Vickers hardness measurement before and after the make up of the butt microhardness was measured, the measurement results show that the hardness of the specimen did not change before and after welding repair, a welding repair does not change the hardness of the sample.

Around used the micro vickers hardness survey law butt welding to make up the test specimen microhardness to carry on the survey, the measurement result had indicated around welded makes up the test specimen degree of hardness not to have the change, one time welded makes up has not changed the test

Micro-Vickers hardness measurement method for microhardness of samples was measured before and after welding, measurements show that the hardness of the samples before and after welding no change, welding does not change the hardness of the sample at a time.
