The hydrogen precipitation of different metals, platinum, lead, nickel, iron and titanium, were discussed in different pH value and current density. By using Cyclic Voltammetry to study the reduction reaction, copper, titanium, lead, Ti/PbO2 and Ti/MnO2 as cathode respectively, it is proved that sodium metaborate can be electrochemically reduced to sodium borohydride. The kinetic parameters and fractal dimension of these electrode, graphite, lead iron Ti/PbO2 and Ti/MnOa etc, will be researched.

第二章研究平面分形曲线的构造及维数刻划问题，首先将Bush等人利用实数的b进制小数构造无处可微函数的方法发展到更一般的情形，借助于实数的Cantor级数表达式，构造了一类广泛的无处可微连续函数，使得Bush等人所构造的函数成为本文所构造函数类的特殊形式。

It can operate parallelly in a reduced dimension beamspace in DFT beamspace, and reduce computational complexity.

针对传统多机多目标攻击不易解算攻击任务分配，且计算量大的问题，提出基于划分的多目标模糊聚类算法，该算法根据目标属性的相似性进行多目标分类，可以有效地降低多目标任务分配解算维数，减少运算量，提高解算速度。

The strongly nonlinear pore structures of pulverized coals can be described by the fractal theory. The pore fractal dimensions of 10 pulverized coals, which are in the range of 2.572~2.722, were analyzed on a N2 adsorption porometer. The apparent viscosities of coal water slurries were measured on a Haake rotary viscometer.

用分形理论能描述具有强烈非线性特征的煤粉孔隙结构，利用氮吸附仪分析得到10种煤样的孔隙分形维数为2.572~2.722，利用Haake黏度计测量水煤浆黏度，讨论了孔隙分形、水分、氧量和可磨性指数等对水煤浆性质的影响规律，得到相关的拟合经验公式。

By means of reductional operation, reduces the attribute dimensionality, summarize of the knowledge rule which is suitable for the policy-making support, is one of important applications of the rough set theory.

通过约简操作，降低属性维数，总结出适于决策支持的知识规则，是粗糙集理论的重要应用之一。

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.
