The experiment extract The trypsin used the way of the trypsinogen activated by self, then, according to the characteristic of hydrolysis determinated the enzyme activity. at last,use the method of salting out purified The trypsin.

本实验采取胰蛋白酶原自身激活的方法提取胰蛋白酶，再根据胰蛋白酶的水解特性，采用酪氨酸测定酶活，最后根据盐析的原理，提纯胰蛋白酶。

The prime minister John Howard says Australia could quadruple its 2005 revenue from exporting uranium oxide (mainly to America, France and Japan) if it enriched and fabricated the fuel first.

约翰·霍华德总理说，澳大利亚如果能提纯并制造燃料级的氧化铀再出口的话（主要出口美国，法国和日本），它从中得到的财政收入将可能是2005年的4倍。

The hydration reaction catalyzed by the ion-exchange resin,was used to reduce the content of caryophyllene in the heavy turpentine and get the longifolene of high purity.

以离子交换树脂作催化剂，利用水合反应降低重质松节油中的石竹烯含量，再经过提纯获得高纯度的长叶烯。

When different materials mixed,the mixture will have a mixed melting point of mixture ,and the mixed melting point of mixture is different from the intersoluble solutions.we separate the intersoluble solutions by different melting piont of intersoluble solutions when separate temperature is flexible temperatureThese intersoluble solutions different in melting point, the method would make the high melting point material became solid while the low melting point material still be liquid by adopting cryogenic treatment with stirring so as to meet the requirement of purifying these two solutions.

这种分离方法的特点是利用两种互溶性物质具有不同的熔点，通过低温处理，并同时加以搅拌，震荡，使高熔点物质和低熔点物质形成固液混合体，再对固液混合体进行离心分离得到高熔点的固体和低熔点的液体，从而达到浓缩、提纯两种物质目的。

The selected process consists of several steps as follows. Firstly, ammonifying the oily mixture of PXA pyrolysis by ammonia or aqueous ammonia, then adding the organic solvent to extra

实验结果表明，合适的分离提纯工艺为：先将裂解产物用氨水氨化、有机溶剂萃取，然后用硫酸酸化11-CUA铵盐水溶液、再将粗品11-CUA于合适介质中结晶，得到高纯度11-CUA晶体；优化工艺条件为：氨化pH值8.0～10.0、温度25-35℃，甲苯为萃取剂，酸化pH值1.5～2.0、温度55-60℃，环己烷为结晶介质，粗品11-CUA在环己烷中溶解温度50～55℃、与环己烷初始质量比4：100、结晶前沉降分层时间10min、结晶温度20℃。

The molecular approach to detecting peptide hormones using cDNA probes should also be much faster than the immunological method because it can take years of tedious purifications to isolate peptide hormones and then develop antiserums to them.

采用cDNA探子来测定肽激素的这一分子生物学方法同时也应该比免疫学的方法速度来得快，由于对于免疫的方法来说，需耗费好几年枯燥的提纯进程，方能将肽素分离了出来，然后再培养出针对它们的抗血清。
