循环

It is good style to use while loops when you don't know the number of iterations up front , and a for loop when you do know, and thus do not need to modify the loop variable in the loop body.

当你不想知道循环的前面的数字时，使用while循环是一个很好的作风，当你已经知道了一个for循环时，因此就不需修改循环体中的循环变量。

So the research on the thermo-economics analysis of thermal power plant is significant, this paper focuses on this field and gets some conclusions as follows: Based on Equivalent Enthalpy Drop Method and Cyclical Function Method, a conception, New Heating Steam Flow, is proposed and defined in this paper, which makes it possible to separate the cogeneration circle into condensate steam circle and heating steam circle and to get the new power equation and calculate the Rate of Electrical Power Generation by Heating Steam with Net Equivalent Enthalpy Drop.

在等效热降法的基础上，结合循环函数法的循环分析理论，通过引入热化新蒸汽量的概念，使得常规抽凝供热机组的纯凝汽循环与供热抽汽循环得以分离，从而得出了相应的供热机组汽轮机的功率方程，并实现了热化发电量与净等效热降计算的统一，最终完成了利用等效热降法对供热机组热化发电率的计算，使得已在凝汽机组中应用成熟的等效热降法可以方便地应用于供热机组，进行经济性分析和计算。

The data were analyzed in terms of the procedures, which were explicated by The Grounded Theory in the first stage and The Phenomenology in the second stage. The findings of this study were as follow:(1) The model of drug using was dynamic cycles, including initial drug using, continued using, addiction, reintegration, relapse, re-continued using and re-addiction to drugs. But not all cases entered into this cycle.(2) Some drug abusers may stop using drug because of some reasons, but it was hard to confirm that they didn't reenter this cycle again.

结果发现：进入用药行为的循环历程模式，吸毒者呈现出一个初尝、持续使用、成瘾、重整、再度用药、持续使用、成瘾的循环动态之过程，不过并非每个个案均完全进行循环，在每一个阶段中个案有可能随时因某些因素而中止，但中止并不代表个案即真正戒除毒品，视个案反思、自觉能力的强弱，有无进入深度的痛改而采取行动达到真正的戒除，若无则可能在某些条件的促进下又再度进入吸毒的循环中。
