We consider Grassmann manifold G(2,8) as a submanifold of the unit sphere of /\2 which is the exterior vector space on Rn. Thus we have the induced metric and connection on G(2, n).

把Grassmann流形G（2，n）看作等距地嵌入在欧氏空间R~n上2-外向量空间∧~2中的单位球面上的子流形，得到它上面的度量和联络。

Firstly, the generalization of Fan-Ha section theorem and a general vector variational inequality without convexity assumption and minimax theorem of vector-valued function are obtained. Then, the quasi-montone vector variational inequality problem is concerned.

For solving this nonideal problem, the orthogonality between the directional vector and the noise subspace with the same frequency can be used to establish a cost function. After finding the appropriate solution with the minimum cost function value through different optimization methods, the LCMV algorithm can use the result to calculate the optimum weight.

为了解决这项在波束成型上的非理想问题，我们利用了宽频信号的方向向量会和同频率的杂讯子空间正交的特性[4，5]去建立一个目标函数，利用不同的最佳化方法找出适当的解，再带入LCMV演算法中算出最佳权重。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
