Mathematics and Its Applicationshe CO. level is fairly constant around 300 to 350µ./. due to photosynthesis by plants, and it rises to around 400 to 450 at night. CO. level is more important under cover, especially in plastic houses where air exchange is normally restricted in order to raise temperatures in a cold climate, and as欲望小妹 发表于 2025-3-23 20:11:53

Frank W. Anderson,Kent R. Fullery under cover, is sophisticated, and modeling it is not simple. This is one of the main reasons why most greenhouse models do not have or have only rather simple sub-models of plant growth. In the open field, the time courses of environmental conditions such as air temperature and carbon dioxide con反省 发表于 2025-3-24 10:15:06

Static models are still predominant, and they will be powerful in analyzing particular problems such as comparison of the effectiveness of various thermal screens and estimation of total heat requirements based on actual measurements.不能强迫我 发表于 2025-3-24 20:53:36
