When TiO〓 content is increased, the surfacial energy formed by crystals may be reduced, the devitrification degree, strengthened and the content of wollastonite in crystal phase raised; if Cr〓O3〓 content is increased, the crystal size is enlarged, and the content of diopside in crystal phase, raised; if the sulphide content is increased; the reduction atmosphere is heightened and the content of wollastonite become bigger.

晶核剂浓度研究表明，晶核剂浓度不同，对基础玻璃析晶强度，晶相含量和晶体尺寸有一定的影响，当TiO〓含量增加时，可以降低晶体形成的表面能，析晶强度增大，晶相中硅灰石含量增多；Cr〓O〓含量增加，晶体尺寸增大，晶相中透辉石含量增加；硫化物增多，还原气氛增大，同时硅灰石含量增多。

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.
