The result proved that the main body of research of traditional Chinese medicine is researchers who possessed the fundamentals of traditional Chinese medicine. It is the objects of research of traditional Chinese medicine that origin of a class of traditional Chinese medical literature consisting of herbals which focus on descriptions of individual drugs; the relationship of the technological process of preparing Chinese medicine, as by parching, roasting, baking, steaming, soaking, and simmering, etc.;and technology of separating, extracting and purifying for composition; traditional Chinese medicine dynamics of one of the 12 two-hour periods into which the day was formerly divided before the introduction of western chronology; compatibility of medicines in active compositions; patent, effectiveness for a given period of time and constantly changing of traditional Chinese medicine.The relationship between the main body and the objects was that the former depends on the latter ones and the main body has subjective initiative as fully as possible.展开更多

The study concentrates on analysis of the relationship management on a psychological con- tract perspective, shows that constructing good psychological contract is useful to promote mutual trust, reduce the transaction cost caused by incompleteness of formal contract, avoid the risk of supplier management between the main manufacturer and suppliers of the large aircraft project. And with further understanding of the dynamic contracting process as well as formation framework of psychological contract between the main manufacturer and suppliers, we can better understand the relationship black-box and provide a new perspective for the study of the relationship management, then given some constructive suggestions to supplier relationship management.展开更多
为明确青海蚕豆育成品种、高代品系和骨干亲本的群体结构与亲缘关系,本研究利用46对多态性和稳定性好、重复性高的SSR引物对36个青海蚕豆主栽品种(品系)进行群体遗传学分析并构建了指纹图谱。结果表明,通过毛细管电泳检测,在46对引物中...为明确青海蚕豆育成品种、高代品系和骨干亲本的群体结构与亲缘关系,本研究利用46对多态性和稳定性好、重复性高的SSR引物对36个青海蚕豆主栽品种(品系)进行群体遗传学分析并构建了指纹图谱。结果表明,通过毛细管电泳检测,在46对引物中检测到262个等位位点,各引物检测的多态性等位位点数(Na)为2~15,平均等位位点数为5.696个,平均每个位点检测到的有效等位基因数为2.988个,范围为1.180~9.257;Shannon指数的变化范围为0.287~2.444,均值为1.210;多态性信息含量(polymorphism information content, PIC)值变化范围为0.141~0.883,均值为0.553,揭示了青海蚕豆品种丰富的遗传多样性。系统聚类将36份材料划分为4个亚群,第Ⅰ、Ⅱ、Ⅲ、Ⅳ亚群分别包括24、4、7、1份材料;群体结构与主坐标分析将材料划分为2个亚群,亚群Ⅰ和亚群Ⅱ分别包括17和19份材料,与聚类分类结果有一定程度的交叉重合,厘清了青海蚕豆主栽品种的群体遗传结构与亲缘关系。在此基础上,筛选出4对核心引物,构建了36份材料的指纹图谱,并将相关信息储存在二维码中。青海蚕豆主栽品种指纹图谱的构建不仅为青海蚕豆品种鉴定提供了有效工具,也为今后青海蚕豆品种亲本选配和新品种权保护提供了技术支撑。展开更多
