Then the morphology was observed by optical microscope and SEM. The grain size of austenite, the number of martensite in austenite grains and the spacing of the lath martensite were measured.
用金相显微镜和SEM观察了试样铸态微观组织形态，测定了奥氏体晶粒尺寸以及奥氏体晶粒内马氏体板条束个数和马氏体板条间距。
Dominant group, average spacing and average length of joints are carried out with statistical analysis using data measured from 837 outcrops in these two blocks.
对岩块地表837个露头的节理进行测量和统计分析(节理优势组、平均间距和平均迹长等)。
The measured time delay responses are nearly linear with the wavelength spacing between optical carriers as well as the lengths of FDLs, which agrees well with the theoretical analysis.
实验测得的延时与相邻子阵对应的光载波的波长差以及光延迟线的长度线性相关，这与理论分析一致。
