The whole sintering process of SHS converter fettling materials can be divided into three steps. The first step is the decomposition reaction of carbonates and sodium nitrate, which is an endothermic reaction. The second step is the SHS reaction, i. e. thermite reaction, the metal of Al reacts with CO〓, O〓, NO〓, Fe〓O〓 to form Al〓O〓. The speed of thermite reaction is very quick, and accompanied with large amount of heat emission and temperature rise. The third step is the reaction of spinels formation. The Al〓O〓 produced by SHS reacts with MgO to form spinels.

The upper layer, with homogeneous composition, is mainly composed of intact phosphatic foraminifer fossils and nannofossils as well as abiotic carbonate fluorapatites, representing the biologic and autogenic origin. However, the lower layer, with visible metasomatic texture and relatively high Si, Al, K and Fe, is notably different from the upper one, and seems to have been formed mainly by replacement of carbonates.

上层磷酸盐由大量形态结构清楚的磷酸质有孔虫和超微化石以及非生物碳氟磷灰石组成，成分均一，杂质少，表现出生物成因和原生白沉积特点；下层磷酸盐变化复杂，具有特征的交代结构，混杂较高的Si、Al、K、Fe成分，显示以磷酸盐交代碳酸盐成因为主。

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.
