This paper first gives the definition of tree morphism, and then discusses the scale of use case for operating to a stack using graph theory, and gets some useful properties about operating use case to a stack.

本文首先给出了树同构的概念，然后利用图论就栈操作的用例进行了讨论，并得到一系列有关栈操作用例的重要性质，最后对一个给定任意大小的输入序列，讨论了其各种可能的输出序列，在此基础上得到了各种可能输出序列规模的一个递推计算公式

Given a mesh, we first solve a Poisson equation to construct a scalar field and use it to generate some critical points. The cutting paths between the critical points and the boundaries are solved in the Poisson scalar field using the deepest descent method. For meshes with nonzero-genus, we construct a Harmonic scalar field, and connect the saddle points with the boundaries based on the Morse theory.

The proposed method first uses common subtractive clustering locating method to acquire video object position and moving object number of each frame. Then, the proposed algorithm uses fuzzy C-means clustering algorithm to further cluster the moving object foreground pixel samples. Finally, matrix analysis theory for calculating eigenvalues and eigenvectors of covariance matrix is applied to compute the object scale and orientation parameters.

该算法在减法聚类算法预定位目标位置及获得目标个数的基础上，进一步采用模糊C均值聚类对目标前景样本进行归类，最后通过对目标前景样本协方差矩阵特征值和特征向量的分析获得目标的尺度及方向参数，从而实现对视频运动目标的定位。

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。
