摘要
通过对熵理论的几个基本问题所存在的主要观点进行评述，从而明确得出：1．熵能作为系统无序度的量度，但对复杂系统必须区分不同层次上的熵概念；2．负熵的科学定义应为：当一个开放系统的总熵变小于系统内部的熵增时，可以说系统产生了负熵流，或者说系统引进了负熵；3．“熵量守恒”及“熵与信息的守恒”都是不成立的。
The author has rcviewed existing arguments on the essential aspects of entropy theory and came to following conclusions: 1. Entropy could be regarded as a measuremcnt of disorderness of a system, but entropy concepts at different levels must be distinguished for complex systems. 2. Neg-entropy should be defined scicntifically as: when total change of entropy of an open system is less than the increase of cntropy in the system, neg-entropy is led into the system.3. The convcrsation of entropy and the conversation of entropy and informations are untenable.
