The key point of "desert production" development theory is to raise light energy utilization ratio and to improve primary production of vegetation.
“沙产业”理论的核心是提高光能利用率,强化植物性的初级生产力。
From the second refraction,the light energy which entered the eyes of the observer takes a large proportion of the incident light energy.
根据光的电磁理论,水珠表面直接反射、经二次折射进入观察者眼中的光能占入射能量的绝大部分,所以,水珠晶莹透明,在阳光照耀下格外明亮。
The progress of photosynthetic efficiency and solar energy utilization, the accommodation on adversity of vegetables, and the regulation on temperature and light condition in solar - greenhouse were reviewed in this pape
