  2. The result of the cluster analysis at the individuals level shows that most of the individuals from different populations cluster together and the individuals from one or two populations does n ' t emerge in some phenons, which means that certain degree of morphological and genetic differentiation occurred among populations. this also reflects that there is genetic heterogeneity among individuals or the variation of micro - habitats in a same population. from cluster analysis at the population level we found that there is obvious differentiation between the populations from east hot spring and the populations from other places, this differentiation probably caused by the geographical isolation among those populations

    對所測量的形態特徵的數據在個體水平上進行聚類結果表明，同一種群的個體並不是完全有序地聚在一起，而不同種群間的個體常無序地聚在一起，同時也有一些大的表徵群不出現某些種群的個體，說明部分種群間有一定的分化，這也反映了種群內部個體間的遺傳異質性或由於種群內部微生境的差異導致的種群內個體間的形態異質性。
  3. There are also different in inducing cluster buds from callus of clone gingkgo and its other tissues and organs, some callus can induce cluster buds, but others can not. differentiation rate from the callus of cotyledon can be up to 36 % and the number of cluster buds is positive related to the times of subculturing

  4. In order to analyze quantitatively and evaluate classifiably agro - ecoclimatic resources, based on average data of multiple years from 165 meteorological stations of northwest china ( gansu, ningxia and qinghai ), resource indices cr, efficiency indices ce and utility coefficient k were calculated by applying the dynamic models of agro - ecoclimatic suitability degree. then, based on month to month average data of multiple years of efficiency indices ce, twelve types of agro - ecoclimatic resources were identified through the analysis of fuzzy cluster. the results indicated that latent potentialities, matching condition and utility degree of agro - ecoclimatic resources have obvious characteristics of spatial differentiation. on the basis of the calculation results, the suggestions about exploitation and utilization of the agro - ecoclimatic resources in northwest china ( gansu, ningxia and qinghai ) are put forward

    為了量化分析和分類評價農業生態氣候資源，根據西北地區（甘寧青） 165個氣象臺站多年平均的氣候資料，採用農業生態氣候適宜度的動態模型，首先計算了農業生態氣候的資源指數、效能指數和利用系數；然後通過對多年逐月平均效能指數的模糊動態聚類，劃分出農業生態氣候資源的12個類型並進行了相應評價，結果表明農業生態氣候的資源潛力、匹配狀況和利用程度具有明顯的地域分異特徵，進而在此基礎上提出了開發利用農業生態氣候資源的若干建議。
  5. From the viewpoint of literature research, the paper investigates the development of heart viscera - state theory, and studies the relationship between heart symptoms and syndromes by statistical methods such as frequencies, cluster analysis, and regression analysis to probe into the regulation of syndrome differentiation in heart diseases

    摘要從文獻研究的角度，梳理心藏象理論、辨證論治理論的發展脈絡；對歷代有關心病證的癥象，採用現代統計學的方法，應用計算機進行頻數統計、聚類分析、回歸分析等科學手段，探究心病證與癥象的相關性，歸納心藏象辨證的規律。

    蛋白晶元可以將蛋白質以陣列的方式固定在經化學或生物酶處理的表面上，也可將受體蛋白、抗體等固定在表面上，未知分子可以利用與晶元不同位點親和力來分析。
  7. Cd markers, cd : cluster of differentiation

    標志，分化抗原標志
  8. The species of the " gallica cluster " were, however, only partially separated as chinese armillaria possessed high genetic diversity. for example, although a. sinapina and a. gallica, as well as cbs f and cbs h could be divided by the igs - rflp patterns, the differentiation between a. sinapina, cbs c and cbs h was not possible. in the dendrogram based on the igs - rflp data, the 43 patterns of 11 species were divided into nine groups

    用igs - rflp圖譜類型能夠有效地區分假蜜環菌（ a . tabescens ） 、奧氏蜜環菌（ a . ostoyae ） 、 cbsg和蜜環菌狹義種（ a . mellea ） ，但對于高盧蜜環菌族（ gallicacluster ）的種類，則只能摘要區分部分菌株，這主要是因為中國蜜環菌種具有很高的遺傳多樣性，例如，芥黃蜜環菌與高盧蜜環菌以及cbsf與cbsh可能用igs一rflp圖譜進行區分，但是不能區分芥黃蜜環菌、黃蓋蜜環菌和cbsh 。
