距离

The RAPD was used to study the genetic diversity of 19 KinXin series potato cultivars. The result showed that 52 RAPD bands were amplified using 7 primer, among them 43 bands were polymorphic, and 4~9 bands were amplified in each lane. The RAPD analysis indicated that the genetic distance of 19 potato cultivars was between 0.17~0.72, average value was 0.39. When all of the polymorphic bands were analysed by cluster analysis, 19 potato cultivars were classified into 3 groups. The analysis showed that there existed close sibship among the majority of potato cultivars, and the genetic distance between the minority cultivars and the others is longer, which indicate that the genetic basis of KeXin series potato cultivars is wide.

利用RAPD标记技术对19份克新系列马铃薯品种进行了遗传多样性分析，分别提取19份马铃薯品种的DNA，进行随机引物多态性扩增，从1000条随机引物中初步筛选出7条有多态性的引物进行详细研究，每条RAPD引物扩增出4~9条带，共获得52条带，其中多态性条带为43条；19份马铃薯品种的遗传距离介于0.17~0.72之间，平均值为0.39，平均遗传距离介于0.31~0.51之间；聚类分析结果在GS=0.53处可将克新系列马铃薯品种划分为三类，聚类结果与系谱分析基本相符，同时也说明克新系列马铃薯的遗传基础有所拓宽。

The port city with distance the closest Russia issues a Ning Sike Ye to have 734 kilometers only, be apart from Habaluofusike 971 kilometers, it is a when grow enterprise of pair of Russia commerce, travel natural passageway.

The faintest color of the bud color is yellow green. In addition, the variation-coefficient of some morphological traits is very low such as the cotyledon length, the cotyledon width, the cotyledon color, the silique length and so on. The Cluster analysis was based on the morphological data. When the genetic distance was 7.61, 21 accessions were clustered into 4 groups. The accessions of the group 1 had white petal, mezzo flower stalk and the earlier pick period, which is divided into two subgroup when the genetic distance was 5. 98. And the model was Ba39 and Ba35. The accessions in the group 2 had the very slender flower stalk and the middle pick period, that model was Ba27. The accessions of the group 3 had yellow petal, the thin flower stalk and the later pick period, that model was Ba43. The main characters of the group 4 were that it had the latest pick period and many leaves.

基于形态性状的聚类分析，在遗传距离7.61处，把21份芥蓝种质划分为4类，其中类群G1包括14份材料，其植株的生长势中等，株型较为一致，花瓣颜色均为白色，花薹粗细较为适中，平口时期较早，在遗传距离5.98处自然形成2个亚类，分别以Ba39和Ba35为代表；类群G2包括2份材料，即Ba27、Ba33，其植株的生长势较弱，花薹很细，平口时期相对居中，代表材料为Ba27；类群G3包括4份材料，即Ba05、Ba09、Ba38、Ba43，其植株的生长势较弱，子叶颜色、叶柄颜色、花茎颜色、花蕾颜色均为黄绿色，花瓣颜色为黄色，花薹较细，平口时期较晚，代表材料为Ba43；类群G4包括1份材料，即Ba41，其植株的生长势较强，平口时期很晚，并且叶片数很多。

尽人皆知一条古代的辩术，讲的是阿奇里斯①总赶不上他前面的乌龟，尽管他走得比乌龟快十倍；因为每当他走完他与乌龟之间的距离时，乌龟又超前爬了这段距离的十分之一了；阿奇里斯走过这十分之一，乌龟则又超前爬了百分之一了，以此类推，直到无休无止。

距离分类器是以已知地物类别的亮度值作为分类基准，通过比较未知类别像元与已知类别像元亮度值间的距离进行分类；角度分类器是以光谱谱线角为分类基准，通过比较n维波段空间中未知类别像元与已知类别像元光谱角度进行分类。

In this paper, an algorithm to achieve both two dimensional high resolution and wide swath is proposed. Every small satellite work in the active state, they transmit and receive different frequency band signal simultaneity. First, the azimuth ambiguity is eliminated in each frequency sub-band, then the signal is rectified to zero Doppler frequency, after that this algorithm does the range spectral synthesis to achieve high range resolution.
