【摘要】 本文主要讨论了生物体个体发育过程中的熵和熵产生率的一般变化规律。给出了生物体在任一发育时刻ｔ的熵以及ｔ→ｔ＋△ｔ时间内熵变的近似计算方法。结果表明，个体发育过程中生物体的熵和熵产生率既不能过大也不能过小，而是要和个体发育各个时期的发育水平相适应。那种认为熵和熵产生率越小越好，越小越有序的观点对生物体这样的系统是不适用的。更多还原

【Abstract】 The genaral changing law of the entropy and the rate of entropy production in the process of ontogeny is discussed. And it is given the entropy of t at any moment of development a principal calculating method about entropy changement in the period of t→t+△t. It is showed that the entropy and the rate of entropy production are neither too much nor too little. They must be adapted to the level of ontogeny. Therefore the view, that the less of the organism entropy and the rate of entropy production, and the more orderly the better is not suitable for organism. This paper only touches upon heat entropy.更多还原
