文章在介绍了气球轨迹法测风和风廓线雷达测风各自原理的基础上，重点分析、探讨了二者间的差异，以及采用风廓线雷达测风的优势与发展风廓线雷达的意义。

So there need not only no failure but working in a stably good condition in the ignition system, the using condition and adjust of the use factors are the most important thing for the system performance. The paper analyses the characteristics of electronic ignition system, points out that determinant use factors are mainly the voltage of battery, the occupy-emptiness rate of the ignition signal, the clearance of spark plug, the resistance of high-voltage part, and the cam angle of spark advance.

本论文重点分析了电子点火系统故障特征，论证了决定电子点火系统性能的使用因素主要有电瓶电压、点火信号发生器发出电压信号的占空比、火花塞间隙、高压阻抗、点火提前角，这些因素在点火系使用过程中故障率占点火故障比例最大，故障出现的频率最高，而且有时常因维修调整不当导致点火系统性能变差。

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.

本论文拟采用密度泛函理论和非平衡格林函数相结合的第一性原理计算方法，选取苯基小分子作为研究对象，构建了金属电极/有机小分子/金属电极三明治结构体系，系统地研究了苯基分子器件结构的改变与分子电输运性质之间的关系以及影响分子器件电输运性质的相关因素，其中重点研究了分子与电极间可能的接触结构改变、官能团、分子间的扭转角以及外电场对苯基分子电输运性质的影响，本论文主要包括以下五个章节的内容：第一章为综述部分，主要介绍了分子电子学产生的背景、分子器件的研究意义、当前研究分子器件的实验和主要理论方法，以及目前在研究分子器件中存在的一些问题，最后给出了本论文的主要研究内容和技术路线。

This study mainly interest in shot size and shot angle, which are the basic elements of Lens language. 3D animation is different from movie while everything can be seen on the screen is through the frame of virtual camera; it concerns the whole visual images of the film.

本研究所关注的重点，是3D动画镜头语言中最基本的镜位使用；同於实拍电影，3D电脑动画使用虚拟摄影机，所有角色的表演、故事的发展、模型的颜色及光影等，都必须透过取景才能呈现，对一部动画具有举足轻重的影响。
