The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

First, we introduce the linearly distributed stress tensors as the source and by means of two-dimensional finite-difference scheme to obtain the response of this source, then the point source response is generated by correcting both the wave forms and geometrical spreadings for the linear respons.

但在理论地震学，工程地震学和勘探地震学中横向不均匀介质中的波传播问题非常重要，此时使用有限差分法和有限元法等离散数值方法比较有效。鉴于目前计算工具的限制，三维模型的有限差分计算虽然在理论上是可行的，但很少能用于实际。

First, this paper illustrates that punitive damages has strong prevention function, at the same time it accords with the inspirit of civil law of modern times, it doesn't conflict with basic theories of civil law, such as the partition of public law and private law, the separation of civil law and criminal law and unjust benefit, it is also the necessary supple

本文首先从理论上阐明了该制度具有很强的预防功能，符合现代民法的精神，与公法与私法的划分、民刑分离、不当得利这些民法基本理论并不矛盾，是补偿性民事责任的必要补充，因此具有存在的合理性。

In order to determine the size of coal pillar scientifically and reasonably, we mainly studied the law of stress distribution of the surrounding rock and the mechanism of narrow pillar drift and high strength bolt support and so on, indicating that using the narrow pillar drift and high strength bolt support can effectively guarantee the stability of gob-side entry in deep mine.

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.
