The fluorescence of dominant species leaves is decreasing at noon shows that efficiency of light energy conversion at noon is decreasing and further to explain photo inhibition.

中午优势种叶片荧光降低表明中午的实际光能转化效率降低，进而说明了中午发生光合作用光抑制。

The motivation for the research and development of fuel cells is mainly related to their potentially light weight, low volume, and high efficiency of energy conversion, etc.

燃料电池研究与开发的原因主要在于其质量轻、体积小、能量转换效率高等。
