So researchers used a statistical analysis to measure the orientation and shape of the galaxies to find small distortions due to so-called weak lensing.
所以研究人员使用统计分析来观测星系的位置和形状，从而找出由弱透镜效应造成的微小偏移。
At present, photothermal deflection technology and surface thermal lensing technology are widely applied in weak absorption measurement.
目前，广泛使用的测量弱吸收的方法有光热偏转技术和表面热透镜技术。
