棱柱体

Translation - urea characteristic The urea is one kind of achromatic color, tasteless, the odourlessness acicular or the orthogonal prism build crystallizes, in the actual production is granulated for the white or the tint; The granularity may be possible to be small greatly according to enterprise's characteristic; When heats up to 132.7℃ starts to melt, the solid urea density is 1.335g/cm 3, dissolves in the water and the few organic reagents, the urea assumes the alkalescency, may live the salifying with the acid function, when the temperature surpasses 60℃, the urea in the acid, the alkalinity or the neutral solution has the hydrolisis.

问题补充：尿素是一种无色、无味、无臭的针形或正交棱柱体形结晶，实际生产中为白色或浅色颗粒状；粒度则根据企业的特点可大可小；当加热到132.7℃开始熔化，固体尿素密度为1.335g/cm 3，溶于水和少量的有机试剂，尿素呈微碱性，可与酸作用生成盐，当温度超过60℃时，尿素在酸、碱性或中性溶液中发生水解。

In this article, the author compares and analyzes three kind of main calculation formulas of the square grid quadrilateral prismoid field leveling earth volume , and provides a formula to calculate directly total excavation and filling earth volume according to construction altitudes of angular points of square grids.

对场地平整土方量方格网四方棱柱体法的3类主要计算公式进行了对比分析，提出了根据方格角点施工高度直接计算场地总挖、填土方量的计算公式。

To decompose prismoid subject into sweepable sub-volumes, the source vertices project into target surface and decompose target surface to many subdomains. The virtual surfaces are found by linking opposite vertices from source surface and target surface, finally cut volume to sub-volumes. It is also designed spheriform decomposition based on geometry character.

虚拟分解主要是通过将棱柱体的源曲面边界顶点映射到目标曲面，将目标曲面划分成和源曲面一一对应的区域，连接对应的顶点建立虚拟剖分曲面，利用虚拟曲面将复杂的几何体剖分成子几何体。

Prismoid specimen shall adopt horizontal type molding; when pour concrete and tamp down the specimen with hidden steel bar, concrete between steel bar and specimen mould shall be taken particular care so as to keep right condition of pouring and tamping compaction.

A formula for the volume of arbitrary quadrangular prism is given by using vector colculus.

本文利用空间解析几何学中的矢量方法和原理求解底为任意凸四边形的四棱柱体积、并推导出其体积公式。

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.
