In contrast, the two rock associations at the south belts were derived from mesomatised lithospheric mantle. However, the ultramfic-alkaline rock association was resulted from immiscibility of parent magma, whereas sodic alkaline rocks were produced by highly differentiation at deep level.

南部的两种岩石组合类型均起源于岩石圈地幔，并在部分熔融之前发生过交代富集作用，但是超镁铁质岩-碱性岩组合为原始岩浆经不混熔作用形成，而钠质碱性岩是原始岩浆在深部经历了高度分离结晶的产物。

The utilization of the 1981 IRRDB Hevea germplasm is very slow in China. For further characterization and evaluation of the germplasm, an analysis was made to evaluate the characteristics of latex regeneration and latex flow of the new Amazon Hevea germplasm by the method of latex diagnosis. Nine accessions of the germplasm were determined in terms of physiological parameters such as yield, initial flow rate, plug index, sucrose, thiols, phosphorus, magnesium, etc, with RRIM600 as the control.

我国橡胶树新种质创新利用进展缓慢，为了深入全面的鉴定橡胶树新种质，加速其利用进程，笔者采用胶乳诊断方法，测定分析了1986年定植于大田鉴定评价圃的14份橡胶树新种质与产排胶密切相关的干胶含量、干胶产量、排胶初速度、堵塞指数及胶乳硫醇、无机磷、蔗糖及镁离子含量等生理参数。

The pigment in colored cotton fibers was extracted by methanol at room temperature. The results of color reactions HCl-Mg reaction, NaBH4 reaction, NaOH reaction, FeCl3 reaction and Pb(Ac2 reaction of the pigment extractive showed that the pigment extracted by methanol was flavone or flavonol with two adjacent hydroxide groups (Table 2, Fig. 1). The results of UV spectral analysis further proved that the pigment extracted by methanol from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring, and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring and indican replaced a hydroxide group at 3-site of A ring Fig.

通过盐酸－镁粉反应、四氢硼钠还原反应、碱反应、醋酸铅反应、氯化铁反应和紫外光谱吸收的分析表明，甲醇室温提取的棕色棉纤维色素可能是黄酮类化合物，B环上带有邻二酚羟基；甲醇室温提取的绿色棉纤维色素除黄酮类化合物外，还含有3-位羟基被糖甙化的黄酮醇类化合物，A、B环上都带有邻二酚羟基。

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.
