But we can prove that the corresponding Eulur\'s function is bounded from below in a proper set S of W_0~(1,p)× W_0~(1,q), and then a minimizer of Eulur\'s function in S gives rise to a solution of the problem.

但是，我们可以证明欧拉泛函在合适的集合S中有下界，因此在该集合中利用变分方法寻找泛函的极小就可以得到原问题的解。

Then one solution would be for Shell to build at P,Esso to build as Q,B.P.as S,and Gulf at T,leaving either Shell or Gulf to build at R;however,if Gulf decides to back out of the whole agreement,then it is clearly impossible for the other three companies to erect the garages in the specified manner.

那么一种解决方法是Shell在P处修建，Esso建在Q处，B.P建在S处，Gulf建在T处，留下一个由Shell或Gulf建在R处；然而如果Gulf退出这一协议(在R和T建汽车修理厂)，则很显然，对其他三家公司来说，无论如何也不可能按照所约定的方式修建汽车修理厂。

In chapter 4, by AREELS, the Generalized Oscillator Strength Density Spectra were measured in the energy region from 56 to 66eV, with the incident energy 2. 5 keV and energy resolution 80 meV, at scattering angles from 0°to 6°, corresponding to the momentum transfer K〓=0.03~2. 01 a. u. The Fano profile parameters f〓 and q for the optically allowed transition 〓(0, 1)〓P°and the optically forbidden transitions 〓(1, 0)〓S〓and 〓(1, 0)〓D〓 were obtained as a function of K〓. With the hyperspherical coordinate wavefunctions, the dynamical correlation are discussed qualitatively. So, a new experimental way to study dynamical electron correlation effect is opened.In chapter 5, the widely used R-matrix theory was introduced. Then, the GOSDS for the optically allowed excitation series (1s〓)〓S〓→〓(0, 1)〓P°(n=2-4) were calculated by this method, and the Fano profile parameters f〓 and q were obtained sequently. So the electron correlation effect can be described by these parameters quantitatively, and the theoretical results were compared with our AREELS experimental results.

在第四章中，实验上，同样使用角分辨的高能量分辨快电子能量损失谱仪，在2.5keV电子入射能量和80meV的能量分辨下，测量了0°到6°散射角下的He原子双电子激发态在56~66eV的广义振子强度密度谱，这种情况，0°~6°对应的动量转移范围K〓=0.03~2.01a.u。，得到了光学允许跃迁的双电子激发态〓（0，1）〓P〓和光学禁戒跃迁的双电子激发态〓（1，0）〓S〓、〓（1，0）〓D〓的Fano线形参数f〓，q等随动量转移变化的曲线；观测到了几个强度很弱、能级很窄的光学允许和禁戒跃迁双电子激发态，用前人准确的理论结果进行了标识；通过比较弱共振〓（1，0）〓S〓和〓（-1，0）〓S〓的强度随动量转移K〓的变化规律，结合超球坐标理论计算的波函数，定性地阐述了在电子碰撞散射过程中它们各自不同的动力学电子关联效应，发展了一套在实验上研究电子关联效应的新方法。

Finally, simulation software was developed with Visual C++ and Delphi for 2D molding analysis of MIM, which affords facilities for the quality forecast of 2D thin wall parts and optimal design of mold and process parameters. In the research of molding performance of MIM feedstock, for the shortcoming of capillary rheometry, it was propounded that using spiral mold test molding performance of feedstock, and a set of spiral mold was creatively designed with quickly exchange gates and closed mold cavity. With the spiral mold, an orthogonal experiment was made on getting regress equation of flow length L〓 of the heavy alloy feedstock. Then the rule of L〓 varying with Q〓, P〓, and ΔT〓 was discovered. Q〓 ranks first in the influence on process parameters of molding performance, P〓 and Δ T〓 second. Therefore the injection rate Q〓 should be controlled primarily to improve the flow performance of feedstock.

在MIM喂料注射成形性能研究方面，针对毛细管流变仪测试法衡量流动性能的不足，提出使用螺旋线模具测试喂料熔体的注射成形性能，创造性地设计了一套可快换浇口，模腔封闭的螺旋测试模，并在螺旋测试模上采用正交实验设计，得出了高密度重合金喂料流动长度L〓的回归公式，揭示了L〓随Q〓、P〓、△T〓和S〓的变化规律，并得出工艺参数对成形性能影响的强度顺序为Q〓最大，P〓与△T〓其次，因而改善喂料流动性能应优先控制注射速率Q〓。

It evaluates the process of feature point matc hing by extracting feature point by the Harris corner detector, forming a correlation matrix in terms of the monogenic s ignal elements｛p,q 1,q 2｝,then to the stage of RANSAC inliers selection so as to eliminate the false feature point pairs and to calculate the fundamental matrix of epipolar geometry.
