This paper deals with the application of the X-ray stress analyzer of Voigt function,in which the size of mosaic blocks and micros train can be worked out with the single-peak measurement.

把单峰测量嵌镶块大小与微观应变的Voigt函数法应用于x射线应力测量仪,并编制了衍射峰形校正和计算微机程序,使得应用x射线应力测量仪能对实际工件进行现场测量嵌镶块大小和微观应变。

The paper introduces mould repaired, that is wire cutting is applied to embedded technology.

The frequency equations about two resonances of free-flooded segmented ring transducer are obtained via traditional analytic method,and then a circumferential symmetry finite element model of the free-flooded segmented ring transducer is established.

溢流式嵌镶圆管水声换能器是一种有效的低频宽带发射器,一般存在2种可供利用的谐振方式,即溢流环的液腔谐振和嵌镶圆管的径向谐振。
