AFLP marker technique was used to investigate the genetic relationships between 50 accessions of maize and its wild relatives including teosinte, Tripsacum and Coix With twenty one AFLP primer combinations of PstⅠ/MseⅠ, 641 AFLP amplified bands were obtained, including 586 polymorphic bands with an average of 30 52 per primer combination and the polymorphism percentage of 91 4% Cluster analysis using UPGMA method based on the data of AFLP showed that the 50 materials could be divided into...

用AFLP分子标记技术对 5 0个有代表性的玉米及其野生近缘种大刍草、摩擦禾、薏苡材料进行了遗传关系分析。利用 2 1个PstⅠ MseⅠ引物组合检出可辨认带共 6 4 1条，其中多态性带 5 86条，平均每对引物得到 30 5 2条多态性带，多态性 91 4 %。聚类分析结果表明，可以将 5 0个材料分为 3大类，与已有的玉米族分类一致，但与玉蜀黍属内的种间和种内分类存在差异，说明大刍草各种内存在较大的遗传多样性。本实验发现玉蜀黍属与摩擦禾关系比与薏苡的关系更近，但并没有发现玉米与小颖玉米亚种比与其他大刍草的遗传关系更近。

Through hang together the simplex data model based on dissection and conventional GIS data model, we develop a integrated and polymorphic model, object oriented unified model of tessellated simplex and conventional GIS, which convenient to inherit and congregate. The model manage the abstracted data accord to 4 level factor, that is geometry object model, topologic geometry object view model and geography object model.

ISSR Marker has strongpoint thereinafter:high polymorphic,the quantity of DNA used is few and low request to quality,nonradiative,the technology difficulty is low,simple operation,good repeatability,less time and so on.

ISSR标记具有多态性高，DNA用量少且质量要求低、无辐射、技术难度低、操作简单、重复性好、耗时少、成本低等优点。

The adverse side effects of drug may induce polymorphic ventricular tachycardia or torsade de pointes, which can increase mortality of the cardiovascular diseases.

从90年代CAST和CASTII试验结果公布以来，人们开始重视抗心律失常药物治疗的收益与风险评估。

Torsade de pointes is a kind of polymorphic ventricular tachycardia due to repolarization prolongation, it could induce cardiac sudden death, and set us an ever-increasing appreciation.

尖端扭转型室性心动过速(torsade de pointes，TdP)是一类与复极延长有关的多形性室性心动过速，可导致心源性猝死，正越来越引起重视。

The main reason is that bending-strain induces the microstructure phase-transformation of the pentacene polymorphic film from "thin-film phase" to "triclinic bulk phase",which results in the performance degradation of OTFTs.

其主要原因是，pentacene薄膜在反复的变化弯曲作用后，薄膜内部发生了微观结构的相转变过程，从而导致器件性能的降低。

Genetic diversity among 7 populations of Trillium tschonoskii were analyzed by using inter SSR and amplified fragment length polymorphism molecular markers. The results were as follows:(1)ISSR: 12 out of the 100 primers showed consistent banding patterns and amplification, a total of 135 bands were produced with an arrange of 250-2500bp, 46 of which (34.07%) were polymorphic.

应用锚定SSR和限制性片段多态对7个延龄草居群的遗传多样性进行了分析，结果如下：从100个引物中筛选出12个ISSR引物，在250-2500bp之间共扩增出的135个条带，其中多态性带为46，占34.07％。

If RB1 molecular genetic testing is not available or is uninformative, indirect testing using polymorphic loci linked to the RB1 gene can be used in familial RB to clarify the genetic status of at-risk family members.

如果无法对 RB1做分子遗传学检测或检测无有效信息，用与 RB1基因连锁的多态位点进行间接的检测同样能用于在家族性 RB 中阐明易感家族成员的遗传状况。
