In Emerson's book, I also found a number of proof.

This thesis contains five chapters. Chapter 1 introduces the cause, purpose and value of the thesis and the problems that affect the existence of the east-and-west-facing residence. Chapter 2 analyzes the affecting factors of the facing of residence including the thermo-comfortability, the spiritual and mental state and the ecological environment etc. Chapter 3 analyzes the specific circumstances, under which the east-and-west-facing residence is practicable. For example, in order to enjoy the view, to make good use of the land and to form the endocentric residential area, we can choose the east-and-west-facing residence. Chapter 4 puts forward some measurements, including the planning design, the architecture design and the constitution design, to make the east-and-west-facing residence hot-proof so that we can eliminate the most disadvantageous factor in the south. Chapter 5 gives some examples of the east-and-west-facing residence in the south.

本文分五章，第一章提出本文研究的起因、范围、目的、意义及南方地区东西向住宅存在的问题；第二章分析了影响住宅朝向的各因素(包括热舒适性、精神心理、生态环境等)；第三章分析了东西向住宅在一些特定条件下(如景观、地形地貌、小区内聚围合等)在南方地区的适应性；第四章提出了解决南方地区东西向住宅防热的一系列(规划设计、建筑设计、构造设计等)措施，以解决东西向住宅在南方地区存在的最大障碍；第五章列举了南方地区东西向住宅的一些实例；最后在结语中总结了东西向住宅在南方地区存在的现实意义及实用价值，并展望了住宅建设发展的前景。

They're my proof that the American promise endures.

他们是我的证明，美国的承诺在延续。

By using the CFD software FLUENT, the inner-flow field of centrifugal fans with ruled-surface impeller versus with enveloping surface impeller has been simulated. The static pressure distribution, the dynamic pressure distribution, the total pressure distribution, the turbulent intensity and the speed vector of the two kinds of centrifugal fans are then analyzed and compared. From the calculating results, we found that the pressure distribution, the speed vector and other parameters of the two kinds of centrifugal fans are basically same. This implies that the tool-path generating arithmetic for the machining of the impeller can meet the aerodynamic requirements of the centrifugal fan. Furthermore the method can provide proof for designing department to establish sound manufacturing tolerance for impeller.

最后采用CFD软件FLUENT，利用标准k-ε湍流模型，采用分离隐式求解器，分别对直纹面叶轮离心通风机和包络面叶轮离心通风机整体风机内部三维流场和单个通道流场进行了数值模拟计算，在计算结果的后处理中，对相同坐标值处的静压力、动压力、湍流强度和速度矢量等参数进行了分析与比较，结果表明：在相同的计算参数条件下所得到直纹面叶轮离心通风机和包络面叶轮离心通风机内部流场差别不大，从而揭示所采用的叶轮数控加工的刀位规划方法的规划误差对流体机械动力性能的影响不大，这也为设计部门制定合理的叶轮加工公差提供了依据。
