The gage location then marked on the specimen and the gage is positioned by using a rigid transparent type . 在试件上标出应变片位置，并用一片结实的半透明胶纸将应变片定位。
Power densities that can be tolerated by a gage are strongly related to the specimen which serves as the heat sink . 应变片所能允许的电能密度与起着散热器作用的试件密切相关。
To ensure this, specimens must be of sufficient thickness so that a triaxial state of stress can exist at the flaw tip . 为此，试样必须足够厚，使裂纹顶端处于三轴向的应力状态。
We were delighted when we came across a shapely specimen tucked away in a crack on the underside of a rock . 当我们遇到一个美丽的标本隐藏在岩石下面的缝隙里的时候，我们高兴极了。
A likely solution to this problem, where specimen vibration is present, is to recess the probe into a hard-rubber sheath . 当试样发生振动时，合适的解决方法是把探头放进一个硬橡皮护套里。
