查询词典 dilatometry

The methods concerned include X-ray diffraction ,thermal analysis,dilatometry,acoustic emission and electrical resistance,of which the last one is widely used in that,in addition to the fact that the testing process can hardly affect the samples,it has high precision,simple electro-circuits,and high speed as well.
