The millimetersized tubular crystal selenium was first prepared. By studying the process of treating selenium in ethylenediamine, we proposed the mechanism of the preparation of selenides under solvothermal condition. The selenides came into being from the reaction of metal ions with Se〓, which was obtained by the amine attacking selenium. Moreover, a new precursor to prepare nanocrystalline selenides at room temperature was obtained. From this precursor, we have prepared nanocrystalline silver selenides, copper selenides, lead selenides and cadmium selenides nanorods.

首次报道了采用溶剂热处理的方法制备出厘米尺度的管状结构硒晶体；通过对硒粉在乙二胺中的溶剂热研究，初步探讨了以单质硒为硒源的溶剂热合成硒化物的反应机理应是硒受胺类的亲核进攻变成Se〓而进一步形成相应的硒化物；获得了合成硒化物纳米晶的前驱物，并在室温条件下合成了硒化银、硒化铜、硒化铅纳米晶和硒化镉纳米棒等。

Total of 161 and 166 bands were obtained respectively,and 23 random primers were used to amplify the genomic DNA of the wild and captive green peafowls.The average relative hereditary distance of the wild and captive green peafowls is 0.0555 and 0.1355 respectively;and the Shannon diversity index is 0.4348 and 1.0163 respectively.There is a prominent differentia between the two populations by T-Test of HO.

用23个随机引物，野生与笼养绿孔雀分别获得161和166个扩增片段，计算发现野生与笼养绿孔雀的种群内平均相对遗传距离分别是0.0555和0.1355，两种群间的为0.1635；两种群的Shannon多样性指数平均分别是0.4348和1.0163，有显著性差异。

The logic of the Lac operon is that the proteins required to use lactose are only made when their substrate is available.

The specific primer was further designed. Using the ray floret as material, after RT-PCR, T-A clone and sequencing, a 732 bp sequence was obtained.

进而设计特异引物，以非洲菊舌状花为材料，通过RT-PCR扩增并经T-A克隆后测序，获得一条长度为732 bp的序列。

Again, the public access to the experience of the museum by about a variety of factors - the museum tour route, toilet hygiene, service quality, the external environment, and even museums drink a cup of coffee sold, the museum can improve the physical facilities to to enhance the public's emotions and feelings.

再有，公众在博物馆内获得的体验受各种因素左右——博物馆的游览路线、厕所卫生、服务质量、外部环境，甚至博物馆咖啡厅售出的壹杯饮品，博物馆可以通过改善这些物理性设施来提升公众的情绪与感受。

The titer test showed that the polyclonal antibodies immunonized by two immunogens all had high titer and the longer interval made for obtaining higher titer. The speciality test showed that the polyclonal antibodies immunonized by conjugations MQCA-RSA had the better speciality than the other one. Usage of RSA as the carrier protein could avoid producing antibody for carrier protein.

以两种偶联物为不同免疫原、采用不同的免疫时间间隔免疫新西兰大白兔，获得多克隆抗体，抗体效价测定和特异性鉴定的实验结果表明：两种免疫原均能产生高效价的抗体，免疫间隔延长有利于效价提高，且以RSA为载体有利于避免针对蛋白载体的抗体产生。

A process for preparing the recombinant chicken gamma-interferon (rCHIFN-gamma) with high activirus activity includes such steps as cloning ChIFN-gamma gene from eukaryotic plasmid to transfer carrier by dual enzyme servenings to obtain recombinant transfer plasmid pFASTBACI-ChIFN-gamma, taking DH10Bac competent cell, adding IngpFASTBAC1-ChIFN-gamma, transposition, diluting to culture object by SOD culture medium, coating on Luria plate, culturing, choosing white clony, purifying, naming positive plasmid as Bacmid-ChIFN-gamma, extracting its DNA, and transfecting Sf9 cells.
