而采用二维方式设计光纤光源的都卜勒流速计模组量测稀释血液流速，可了解在血管某截面上红血球二维的流速情形，所得到的实验结果，可作为发展小型面积化雷射都卜勒模组的基础。

The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

介绍了该膨胀机的设计方法，给出了标准空调工况下的计算结果，详细讨论了两级旋叶式膨胀机的工作过程，并对两级膨胀机与传统旋叶式膨胀机的区别进行了论述，最后分析了滑片倾角对工作腔基元容积的影响，结果显示，滑片倾角对工作腔基元容积的影响很小，在膨胀机的设计过程中忽略滑片倾角的影响是合理可行的。

In this thesis,based on the DFT+NEGF first-principles method,we construct a lead-molecule-lead sandwich system with single benzene-based molecule to investigate the relationship between the structure and properties of the molecular devices and the factors that influence properties of the molecular devices.Our computational investigations on these molecular devices are primarily concentrated on the effect of contact geometry between molecules and electrodes,the effect of side groups,the effect of different torsion angle between two phenyl rings and the effect of external electric field.This thesis consists of five chapters:In Chapter one,we mainly introduce the research background and development of the molecular electronics,including the experimental fabrication of molecular electronic components and theoretical simulation methods.Afterwards we discuss the questions that need to be solved in this area.Finally,the main contents of this thesis are listed.In Chapter two,we introduce the theoretical methods used in this thesis, including the main first-principles calculation methods,i.e.,the Density-Functionmethod and nonequilibrium Green\'s function.
