一、基本的地貌学概念 侵蚀旋逥(erosion cycle):又称地貌旋逥。是 戴维斯提出的一种地貌发展的理想模式。指一个平坦地区 由于地壳运动而被抬升,其后在长期的地壳稳定条件下, 地貌受长期侵蚀作用经历幼年期、壮年期、老年期三个地 貌发展阶段,称一个侵蚀旋回。又一次地壳运动后,准平 原再度被抬升,地貌有进入一个新的侵蚀旋回,称侵蚀回春。这一学说所假设的构造运动条件过于简单、机械;在 论述地貌发育过程时,单纯强调流水侵蚀作用,带有主观 性;对侵蚀旋回发展阶段只用演绎的方法,比较片面

Capital cost projects begin when a need is defined that cannot be satisfied in existing facilities. Thus begins the life cycle of a capital project (Fig. 1). Once started, the project will progress through all of the following phases or be canceled. It all starts with the recognition of a need that will require capital plant. In the conceptual phase of the project, multiple approaches will be evaluated and one or more plans will be evaluated for meeting these needs

一、卡诺循环（Carnot cycle ） 1824 年，法国工程师 N.L.S.Carnot (1796～1832)设计了 一个循环，以理想气体为工作物 质，从高温T2热源吸收Q2的热量 ，一部分通过理想热机用来对外 做功W，另一部分Q1的热量放给 低温T1热源。这种循环称为卡诺 循环
