Bucher diagram is that the carnot cycle characteristics, a simple and practical m-xt Bucher diagram paper, the start of the carnot cycle is used to express the prototype, after the further improvement and to promote its application in various thermodynamic cycle as Rudolf circulation, three heat cycle, reverse circulation within a brief reversible, makes people aware of the limits using Bucher diagram, the rich contents.

Bucher图是表示卡诺循环特性的一种简单而又实用的新图，本文对Bucher图的最开始的用于表示卡诺循环的原型，之后对其进一步的改进和推广使其应用于各种热力学循环如狄塞尔循环，三热源循环，逆向内可逆循环等作了简要的叙述，使得人们了解到Bucher图的使用范围的广泛，内容的丰富。
