specimen grating

• 1. 试件栅: specimen grating
• 2. 零厚度试件栅: zero-thickness specimen grating

• 1.另外一个重要特点是，它对试件栅栅线的反差要求不高，故可以用在氧化情况严重的金属高温热应变的测量中。
  Another important feature of this method is that it can be used for the measurement of high temperature strains even at serious oxidation.

• 2.在几种不同材料的试件表面刻蚀出了试件栅，这种技术的实现使云纹干涉法和精细网格法在高温高压环境下的广泛应用成为可能。
  The realization of this teChnique makes it possible to apply the Moire interferometry and lattice method under high-temperature, high-pressure environments.

• 3.测量中，把扫描隧道显微镜的探针扫描线作为参考栅，把物质原子晶格栅结构作为试件栅，对这两组栅线干涉形成的云纹进行了纳米级变形测量。
  In the measurement, the moire pattern is generated by the scanning line of scanning tunneling microscope and the atomic lattice of substance as a specimen grating.
