Generally it includes three steps: light intensity measurement, scenario analysis and exposure compensation. And auto-exposure has optics-implemented way and electronic-implemented way.

一般包括光强测量、场景分析和曝光补偿等三个步骤，可以用光学和电子学两种方式来实现。

The maximum photosynthetic rate, light saturation point, light compensation point and dark respiration were smaller under weak light intensity than those under strong light intensity.

弱光生境中秋茄幼苗的最大光合速率、光饱和点、光补偿点和暗呼吸速率较低。

The light compensation point (LCP) and light saturation point (LSP) of A. oxyphyIla improved with light intensity enhancing.

随着光强增加益智光补偿点（LCP）和光饱和点（LSP）均会提高；
