Based on purification by alcohol precipiation,the purity of black wattle bark tannins was increased by 10%.

通过对黑荆树皮单宁进行醇沉纯化，可以使单宁质量分数提高 1 0 %。

Furthermore, adsorption characteristics of immobilized black wattle tannin that has higher thermal stability were investigated in details.

进一步研究了固化黑荆树皮单宁的吸附动力学、吸附柱动力学，以及温度、pH值等对吸附平衡的影响。

The purification of black wattle tannin by gel column chromatography showed little effect on the complex stability constants.

用柱层析提纯的黑荆树单宁对其金属络合物的稳定常数的影响不大。

Ahead were the Black Mountains and we climbed among them, watching the steep fields end at the grey walls, beyond which the bracken and heather and whin had not yet been driven back.

再往前就是布莱克山脉。我们上山后，看见陡峭的原野止于灰色的墙脚下，墙外是还没有被人们清除的蕨类、石南和荆豆。

Because of its apomictic reproduction character, an accurate and rapid identification of the F_1 hybrid seedlings of Malus xiaojinensis is of great importance to both genetic study and utilization of the precious genes in the germplasm.

为了建立用现代分子标记鉴定苹果杂种实生苗的方法，在本论文中我们对小金海棠和山荆子F_1代杂交实生苗79个单株进行了RAPD分析，并用SSR标记对RAPD标记的初步鉴定结果进行了进一步的验证。

Objective:By histochemical method, the four biotinylated lectins (DBA, SBA, WGA, UEA 1) were used to study changos in glycoconjugate expression on the surface of endometrium of 28 cases of RSA without obvious reasons in secretary phase, at the same time, endometrial biopsies were taken for histomorphologic evolution.

本文通过生物素分别标记的双花藕豆凝集素、大豆凝集素、麦胚凝集素及荆豆凝集素（UEA－1）与子宫内膜的反应，应用S－P法研究28例无明显原因反复流产的分泌期子宫内膜糖复合物的变化及与其组织形态学分期的相关性。

MethodThe extracts was prepared by grinding 800-1 000 mg fresh leaves of Clerodendron inerme and Vitex rotundifolia added with liquid nitrogen. The sample of total RNA was prepared by centrifugating the extracts added with reagent at 4 ℃, centrifugating at room temperature after ice bath and centrifugating at room temperature after adding reagent in order.

方法］取800～1 000 mg许树和单叶蔓荆的鲜叶，加液氮研磨后制成提取液，提取液加试剂4 ℃下离心，冰浴后室温下离心，依次添加试剂后室温下离心，即得total RNA样品。

The HPLC system column, mobile phase of CH3CN-3%CH3COOH (11∶89) mixture, with detection wave at 270 nm, was used to determine the content of vitexin in Leaf of Crataegus pinnatifida Bge.

应用反相高效液相色谱法测定了山楂叶总黄酮中牡荆素的含量。C18柱作为色谱柱，乙腈-3%醋酸水溶液(11∶89)为流动相，检测波长270 nm，按外标法定量。

Smoldering combustion is a unique combustion phenomenon; its spread may cause disasters and damage a forest. In order to determine smoldering combustion characteristics so as to provide a theoretical basis for preventing and controlling forest fire, the paper made some combustion experiments on litters from Keteleeria evelyniana, Cupressus torulosa and Acacia mearnsii with a fuel bed designed by the authors.

为进一步了解森林凋落物的阴燃特性，为科学地防控森林火灾提供理论依据，用自行设计的燃烧试验床对云南油杉Keteleeria evelyniana、藏柏Cupressus torulosa、黑荆Acacia mearnsii这3种年凋落物积累量大的树木的凋落物进行了阴燃试验，对阴燃过程中的温度变化数据进行了实时采集。

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.

交际能力和语法的关系应该是目标与途径的关系。
