植物的能量利用与热机原理初探

The Principle of Heat-Engine in Plants

该文揭示了植物的热机原理，并通过热机过程，定量地论证了光合固能、蒸腾耗能、长波辐射放能、“呼吸”释能、叶片增温贮能的相互关联的动态关系，阐述了植物用能主要是利用光能质量。同时，通过植物热机各种效率公式，论述了水分与能量的内涵关系，提出了水分携带能量、水分调控有效能的利用率、水分使役能量质量的观点，论证了植物叶片含水量对其它生理指标的影响和控制作用以及植物热机的性质。

The article reveals the principle of“heat-engine” in plants and expounds its nature. By using the theory,the author proves quantitatively the connected dynamic relationships among various energies,expounding that the quality of light energy is the main source of the plant consumed energy. Through various efficiency fromulas of the principle of “heat-engine” in plants,the author brings into light the intensional connection between water and energy in plants, suggesting the views that water can carry energy,control the utilization of effective energy in plants and be the dominant element to the quality of energy; while stating the influence and controlling effect the content of water in blades on other physiological index.
