The discrete element method and the finite element method have their own advantages and weaknesses. Basically, the DEM was developed for predicting the failure problems accompanying with the transition from continuum to non-continuum media. However, it is not accurate to calculate the problem of continuum media. The FEM may forecast the failure area of the material reasonably, while it is hard to calculate the failure process in brittle media. Therefore it becomes a good choice to combine the two methods to construct a hybrid model.

离散元法和有限元法等数值计算方法各有其优势，同时也都存在不足之处：离散元法适于处理由连续介质向非连续介质转化的破坏问题，但对于连续体计算结果精度不高；有限元法适于预测材料破坏的区域，但难以直接用于计算脆性材料破坏过程，因此将两种方法结合可以形成一种较好的混合模型。

Finally, by means of electrometric method, the stress of the exterior surface of the feed inlet was measured. The curvilinear figure of the stress distribution of the exterior surface was drawed and compared with the results of the finite element analysis. The rationality of theory analysis and the reliability of finite element analysis were verified.

This paper is devoted to solving linear saddle point problems, Specifically, We consider nonsymmetric systems, written as usual in block form, where the upper left block is an invertible linear operator with positive definite symmetric part. Such saddle point problems arise, for example, in certain finite element and finite difference discretizations of NavierStokes equations, Oseen equations, and mixed finite element discretization of second order convection-diffusion problems.

When we are designing a webpage, sure meeting considers the issue of resolution, science and technology develops what we use normally now is the resolution of 1024*768 and 800*600, now the width that is used to 778 to resemble element is more very on the network, often make whole webpage very depressive below the resolution of 800, have kind of airtight feeling, actually this width is the widest width that points to the webpage on the resolution in 800*600, do not represent optimal visual sense, might as well the elephantine element that tries 760~770, no matter be in 1024 still can achieve below the resolution of 800 relatively the visual effect of beautiful.

我们在设计网页的时候必定会考虑到分辨率的问题，科技发展到现在我们通常用的是1024*768和800*600的分辨率，现在网络上很多都是用到778个象素的宽度，在800的分辨率下面往往使整个网页很压抑，有种不透气的感觉，其实这个宽度是指在800*600的分辨率上网页的最宽宽度，不代表最佳视觉，不妨试试760~770的象素，不管在1024还是800的分辨率下都可以达到较佳的视觉效果。
