Results were showed:α-HT was extracted from soft leaves and stems of Ampelopsis cantoniensis by hot water, and then purified by re-crystallization.

结果表明，用水或乙醇作为溶剂对该植物进行热浸提，然后利用α-HT 难溶于冷水、易溶于热水的性质采用重结晶的办法对其进行分离纯化。

The regional metamorphosing-crystallization is divided into three mineralization stages which are low amphibolite facies, high greenschist facies and low greenschist facies.

区域变质－结晶成矿期又分为与低角闪岩相、高绿片岩相和低绿片岩相对应的3个成矿阶段。

The crystallization thermodynamic data, such as solubility, metastable zone and other basic data of 6APA were measured based on experiments, which demonstrated that as an ampholyte 6APA can exist in solution as a combination of anionic, zwitterionic and cationic species.

实验数据证明6APA是一种两性化合物，其结构以及溶液行为类似于普通氨基酸，在溶液中以两性离子、正离子以及负离子的形式共存，通过改变溶液的pH值，可以极大地改变6APA的溶解度，这就是6APA等电点沉淀的原理。

The purity and yield ratio of amygdalin were 80.05% and 7.1% under above process, and the purity of re-crystallization was 95.16%.

经过上述方法所得的苦杏仁苷纯度在80.05%左右，得率为7.1%，再次结晶纯度可达到95.16%。

XRD results indicated that the presence of TPA retarded the crystallization of titania and stabilized TiO2 in anatase phase.

XRD结果指出TPA的存在延迟并抑制了TiO2的晶化以及稳定了锐钛矿晶相。

In the high-grade metamorphism and anatexis process, in which sapphirine was formed, the multistage crystallization of minerals resulted in the complexity of the mineral association, such as the differentiation of leuco-and melano-components. Generally, the mafic-rich minerals formed earlier, and the differentiation of magnesio-and iron-components is responsible for the earlier presence of ironrich minerals, i.e., magnesio-rich minerals crystallized later, thus the successive associations of multistage occurred.

在形成假蓝宝石的高级变质-深熔作用过程中，岩石矿物组合的变化主要是多阶段变质造成的，如浅-暗色组分发生了分离，其中含镁铁组分多的矿物较早结晶，而镁铁组分的分离使得相对富Fe的矿物较早结晶，即晚期形成的镁铁质矿物更富Mg组分，并形成递进演化的不同阶段的组合。

Kb, probably in the crust-mantle transition zone. The plagioclase phenocrysts are dominantly andesine with reverse zoning, and those of hornblende are Al-rich (Al2O3 ~15.9 wt%), indicative of high-pressure crystallization.

斜长石斑晶主要为中长石且具反向分带，而富铝的角闪石斑晶（Al2O3 ~15.9 wt%）也反映了高压结晶的特点。

Ankerite crystallization occurred at 320-370℃.

铁白云石的结晶作用发生在320~370℃。

It is shown experimentally that graphite layers in CNT can grow and form annual ring structure with the better crystallization degree at high temperature.

实验结果及理论分析表明，高温下碳纳米管管壁中的石墨层片易于形成自组建的封闭结构，最终形成晶化较好的同心圆柱形结构。

According to the fluid components and their contents in the studied host minerals,it is inferred that the crystallization order of the studied host minerals are anorthite, crysolite and then augite.It is also concluded that the hydrocarbon and water maybe primarily came from sedimentary strata when lava is arising.

根据这3种宿主矿物中流体成分及其含量变化特点，推断这3种宿主矿物的结晶顺序为钙长石、贵橄榄石、普通辉石，并认为流体包裹体中的烃类和水可能主要来自熔体上升过程中所接触的沉积地层。
