Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.

说明早期成矿流体为富含CO〓、H〓O等的碱性流体，其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源，带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化，带出的Na〓则在浅部形成钠长石脉。

In section 1.3, taking the advantage of the classification by the index arrays ,pointed out the space spanned by class A,B,C respect!vivety are subalgebras of NQ. We also show that the subspace spanned by the elements of length 2 in C is an abelian subalgebras of NQ,denoted by H.we find H is contained in the center of subalgebra P of the subspace spanned by the elements in class C.

在1.3节中，应用指标数组我们讨论了各类元素的性质，指出其第A，B，C类元各自张成的子空间均是N_Q的子代数，特别是C类中所有长度为2的元素张成了N_Q的Abel子代数H，且含于C生成的子代数P的中心Z中。

The experimental results showed that under the reaction temperature of 80℃,using catalyst 5 % of the mass of turpentine,reaction time of 10 h,turpentine:solvent:assistant:water of 1∶1∶1∶2,the conversion ratio of 90 %,the selection of α-Terpineol production was 64.96 %,and ΔHφf,g and Sφg were estimated as well...

实验结果表明，在反应温度80℃，催化剂用量为松节油质量的5%，反应时间10 h，松节油∶溶剂∶助剂∶水为1∶1∶1∶2时，其α-蒎烯的转化率为90%，生成α-松油醇的选择性为64.96%。并对α-蒎烯和松油醇理想气体的△Hfφ，g、Sgφ进行了估算，为今后的理论研究提供了数据支持。

The software of Mathematica is applied to numerically calculate the force and draw the υ-h curve, and the theoretical curve in accordance with that obtained in the experiment.

并应用Mathematics软件对受力表达式求数值解，画出υ-h图，与实测的υ-h曲线对比基本吻合。

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.
