This paper, firstly, after a deep study of image mathematical models, sets up two kinds of image models namely Laplace partial differential equation model and biharmonic equation model and then obtains the eigenvectors of image by the methods of eigenfunction expansion and boundary recurrence.

本文首先较深入地研究了图象的数学描述，提出图象的Laplace偏微分方程和双调和方程两种模型，继而采用特征函数展开法和边界递推法分别求得图象的特征矢量。

The result shows: the maximum of the exchange bias field moves towardsthe easy axis with increasing the biquadratic coupling field or bilinear coupling field;additionally, the oscillations of the curves for the angular dependence of exchangebias field become weak and gradually resembles the sine function with increasing thebiquadratic coupling field.

结果发现：双线性耦合或双二次耦合的增加都可使交换偏置场的最大值位置向易轴方向靠近，并且双二次耦合的增加使交换偏置场随外磁场的角度变化曲线的振荡也随之减弱，变为类似于正弦函数的图象。

Based on traditional magnet circuit anglicizing way and permanent magnet drawing and by using traditional BLONDEL theory, A model for electromagnetic calculation and formulas for voltage are obtained by dealing with the d- axis and q-axis electromagnetic coupling of the double- winding armature reaction.

In this paper, we mainly study the spectrum of simple connected graphs and the the double cyclic graph, achieving some new results.

本文中我们主要考虑一般简单连通图的谱半径的可达上界，以及双圈图的树图的谱半径的界，并得到一些新的结论。

When ATRP of styrene was investigated with 1-phenylethyl bromide/benzyl a,a-dibromide mixture as initiator, the GPC chromatogram shows two elution peaks and the molecular weighs of the peaks are approximately in a 2/1 ratio. It suggests that benzyl dibromide is a difunctional initiator of ATRP of styrene. The analysis of end group using 1H-NMR also proves the result above.

采用1-苯基溴乙烷／α，α-二溴化苄混合引发剂进行苯乙烯的ATRP反应时，所得聚苯乙烯的GPC谱图为双峰，分子量相差一倍，初步证明了α，α-二溴化苄引发苯乙烯ATRP反应时是双官能引发剂，并用~1H-NMR对聚合物结构进行分析，进一步证明了α，α-二溴化苄引发苯乙烯ATRP时是双端同时增长的。

According to the Marr's visual theory, a novel face image presentation model, dual attribute graph , is put forward in the thesis. Each node of the graph has two attributes, local principal component coefficient and Gabor coefficient. So the presentation of face image can be converted from gray level to more high level.

根据Marr的视觉表示理论，本文提出了新的人脸图象表示形式---双属性图表示，属性图中每个节点有两个属性特征，局部主成分系数特征以及Gabor系数特征；从而将人脸图象的灰度级表示，转化为更高一级表示。

Based on rubbing model of a two-disk rotor-stator system with consideration of both rotor and stator dynamics,a numerical integration program is applied to numerical simulation and analysis of the nonlinear dynamics of this system,such as bifurcation,Poincare section map,trajectory of axes,phase trajectory,frequency spectrum diagram and time response.

基于一新型径向-轴向复合碰摩双盘转子-机匣力学模型，利用数值积分和Poincare映射方法，对转子-机匣系统由于径向-轴向碰摩故障导致的非线性动力学行为进行了数值仿真研究，给出了系统响应随转速和偏心量变化的分岔图和一些典型的Poincare截面图、相轨图、轴心轨迹、幅值谱图和时域响应等。
