摘要
由热力学第一、第二定律而产生的物理化学的主要内容———焓 (H)、熵 (S)、自由能 (G)及其关系ΔG =ΔH -TΔS来模拟生态系统的物质能量流动过程 ,得出结论 :生态系统的熵值随系统能量的增加而增加 ,反之亦然 ,并及时纠正了 5种错误观点 ,与现实进行了科学印证 。
By the first and secondary law of thermodynamics, made the main content of physical chemistry-enthalpy (H), entropy (S), free enthalpy (G), and their connection:ΔG =ΔH-TΔS(ΔG is change of G, ΔH is change of H, ΔS is change of S, T is absolute temperature ,follow is the same),to simulate the process of current of substance and energy in ecological system. Discussed a conclusion:the S of system increase with the energy (H) of system increase, in the opposite hand, it is true. Discussed 5 erroneous viewpoint ,and made them right,and made confirmation in fact scientifically and the direction of production.
