The basic character of a mass spring oscillate in small amplitude and small angle is studded with an analytic method founded on nonlinear dynamics.

以非线性动力学理论为基础，用解析方法分析包括有质弹簧在内的弹性摆小振幅、小摆角的基本运动规律。

In order to reduce the maximum combustion pressure and the NO, emission, it adopts smaller advance angle of fuel delivery. In most conditions, the combustion starts after TDC; the maximum rate of pressure rise, the combustion pressure and the heat release rate are lower; their relevant phases are retarded.

结果表明，为降低最大燃烧压力及NO、排放，小缸径直喷增压柴油机采用的喷油提前角较小，柴油机在大部分工况下，燃烧始点较迟，最大压力升高率、最大燃烧压力较低，其对应相位较迟，放热规律也较低。

Based on the method of minimum deviation angle, man can obtain the accuracy of measuring refractive index of glass at 3×10-6 with fine apparatus for measuring angle, but the classical princip1e formula quoted by these literatures have principle formula error about 4 ×10 - 4 order which lead to an erroneous measure result.

在这些测量折射率的方法中，最重要的是最小偏向用法和V棱镜法。推导最小偏向角法和V棱镜法的所有文献都沿用经典的原理公式，而这些经典的原理公式没有考虑到空气实际折射率对被测试样折射率的影响。

The results show, when the prism wedge angle is 4°, the transmitted laser beam changes about 1 μrad as the prism rotates 1′; when the small angle deviation on one side of the minimum deviation angle of each prism is controlled, the scanning range of laser beam in the horizontal and vertical direction is not less than 500 μrad, and the scanning precision of the device is superior to 0.2 μrad.

结果表明：取棱镜棱角α为4°时，棱镜每旋转1′，透射光束变化约1 μrad；分别控制双棱镜在其最小偏向角一侧小角度偏转，可以实现光束在水平方向和垂直方向500 μrad范围内的精确扫描，装置的扫描精度可以达到0.2 μrad。

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.

Test results show that Taichung Harbor Sand/ concrete block, the interface friction angle and shear strength are difference, related with the size of the grid opening, the grid number of horizontal opening, Soil and the geogrid system has more obvious acts, such as the shear stress to the displacement of shear increases, the interface will increase friction angle.

试验结果得知在上盒台中港砂/下盒混凝土块体，其影响界面摩擦角与剪力强度差异是与格网横向勒条数，开孔大小有关格网横向勒条数越多且网目越小，土壤与格网互制行为越为明显，剪应力将随著剪力位移的增加而增加，界面摩擦角将会提高。

On the basis of the modeling and analyzing of the transmission system of the PQS-3-D elevator for car in the preamble, this article analysis the reason of the small difference of the angular speed, angular acceleration, angular displacement curve between the bilateral symmetry components. Actually, it is the result of that the torsional rigidity of the bilateral drive shafts are different, therefore has made the revision suggestion to the drive shaft parameter.

在对PQS-3-D型汽车专用升降机传动系统建模分析的基础上，分析左右对称传动构件的角速度、角加速度、角位移曲线在系统起动时间内有较小差异的主要原因，发现是由于左右传动轴的扭转刚度系数不同造成的，故对传动轴的参数做了修改建议。
