摘　　要：本文提出了一种新的绝热法。和一般绝热法所不同的是，该方法仅从环境角度出发，故不需要选择被考察体系的独立变量，也不需要引入关于体系性质的各种不一定具有普遍意义的假定或猜测，体系的任意性由此可得到保证。为了使环境的任意性也能得到保证，本文对环境热源的性质也不作任何限制。本文还从逻辑学的角度对热力学的一些结论作了考察，指出某些条件的非必要性，并给出了熵增原理等一些重要结论的充分必要条件。本文还通过对可设计假定的分析，指出了公理化热力学应有的特点。A new adiabatic approach to entropy is presented. Since the new approach starts from the surrounding of system, many implied hypothesis about system, such as those related to the choice of coordinates and the topological structure of state space can be avoided in the approach. The universality of the surrounding is also ensured. analysis to some conclusions in thermodynamics was also given which indicates than some condition are not necessary. The sufficient and necessary conditions for some conclusions such as that of entropy increasing principle are given. From an analysis to a hypothesis, the features of axiomatic thermodynamics are discussed。
