Evaluating three fracture models and the result of electrical analogy. electrical analogy to the production potential of vertical fractured wells is a kind of analogy between mechanism modeling and scale modeling, the result of it is approximative and the shape of the curve is relatively good, but it is relatively bad in quantification, it can be replaced by the result of mathematic simulation.

对三种裂缝模型以及电模拟结果进行了理论评价，认为对垂直裂缝井产能的电模拟是一种介于机理模拟和比例模拟之间的模拟，其给出的模拟结果是近似的，曲线形状比较好，但定量结果比较差，可以通过建立数学模型，用数学模拟结果取而代之。

In these years, I obtain numbers of the contests item of the reward in math and physicses, Including national mathematics The first prize and physics of Beijing the first prizes of contests of league matches, choose school as grades of student having specialty model many times too, But the title of the special aristogenesis of obtaining area is still since the dawn of human civilization the first time.

我的中学生活已经过去快五年了，在这五年之中，我获过很多次数学、物理的竞赛奖项，其中包括了全国数学联赛的一等奖和北京市物理竞赛的一等奖，也被多次评为校级特长生标兵，不过获得区特优生的称号还是有史以来的第一次。

The persistence, existence, stability and global attractivity of periodic solutions of Lotka-Volterra systems are an important direction of mathematical ecology research.

2About the consistency between the questions, after statistics testing the point biserial correlation coefficient of each question, we find that all mathematics achievement test questions and hematics aptitude test questions both have consistency, and they are positive correlation with the point of each question, except the ninth question from mathematics aptitude test.

在试题间的一致性方面，经过每一道题目的点二系列相关系数经过统计考验后，发现「数学成就测验」全部试题，「数学性向测验」除第19题外，皆具有试题间的一致性，与每一道试题的得分皆成正相关。

It is an important branch of mathematics and it has developed into a bulky subject and has been extensively applied in other natural sciences such as mechanics, calorifics, theoretical physics and other branches of mathematics.

复变函数论是数学的重要分支之一，它本身在发展中已成为一门庞大的学科，而对其它的自然学科，如力学、热学、理论物理及数学的其它分支，复变函数论均有重要的应用。

Based on mastering traditional classification model of thematic cartography elements, we apply fuzzying mathematics, statistics, information theory and so forth, to cartographical data processing model, perfect each model of making sure of grading circumscription, and build an algorithm how to automatically fix on the number of grading.

本文在掌握了传统的专题制图要素分级模型的基础上，把模糊数学、统计分析及信息论等近代数学方法运用到了地图数据处理模型中来，提出并完善了各个分级界限的确定模型，并建立了如何自动确定分级数的算法模型。

It is a common feature that the models have the ability to forecast the changement of water environment.

水环境数学模型在各类应用中有一个共同特点，即对问题有预见能力，这使得数学模型成为解决各类复杂水环境污染问题的有力工具。

Because of the intuition and method of classificational ideology,it becomes the easiest way to let primary school student accept the mathematical idea.

分类思想因其直观性与条理性，是最容易被刚刚接触数学的小学生们所接受的一种数学思想方法。

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。
