Adamson points out that the hardness of an overlay and concrete are not the same, therefore the harder the surface, the cleaner the cut.
亚当森指出，一个覆盖和具体的硬度不一样，因此很难从表面上看，清洁的削减。
Electromagnetic testing and ultrasonic testing are the main points for materials hardness, hardness depth, crystallite size, limiting intensity etc.
对材料硬度、硬化层深度、晶粒大小、极限强度等主要采用电磁检测和超声检测。
The equipment is automated (and quite expensive,) but the results are repeatable and generally consistent with Shore a results within about five hardness points.
其设备是自动的(也相当昂贵)，其结果是可重现的，并在大约五个硬度点内和ShoreA的结果有很好的一致性。
