摘要
由统计物理学中熵与热力学概率的波耳兹曼关系 ,用概率统计的方法 ,得出了理想溶液中某组分的化学势与该纯组分的化学势之间的关系 ,说明了实际溶液中某组分的化学势与该纯组分化学势之间的关系 ;并利用得到的实际溶液中某组分的化学势的关系式 ,对植物生理学中渗透现象中的渗透压进行了分析 ,得出了稀溶液的渗透压与溶液浓度和热力学温度成正比的关系 ,即范托夫定律。
Based on Bolzmann relation of the entropy of statistical physics and thermodynamic probability,the connection of the chemical potential energy between a certain component part and its pure component part in ideal solution was obtained and the relationship of the chemical potential energy between a certain component part and its pure component part in practical solution was also explained by the method of probability statistics.The osmotic pressure of osnotic phenomenon in plant physiology was analysed by using the obtained mathematical model of chemical potential energy of a certain component part in practical solution.The direct ratio of osmotic pressure and solution concentration in thin solution to the temperature of thermodynamics(i.e Fantoph Law) is obtained.
