标记位 meaning in English
flag bit
marker bit
Examples
- At garbage collection time , the mark bits associated with cards in the old generation are examined , and dirty cards are scanned for objects containing references into the younger generation
在垃圾收集时，就对与老一代中卡片相关联的标记位进行检查，对脏的卡片扫描以寻找对年轻代有引用的对象。 - While most production environments use host variables or parameter markers in applications to update their xml data , i ve shown a simple way to do so interactively
虽然大多数生产环境在应用程序中使用主机变量或参数标记位来更新xml数据，但是在这里我展示了用一种简单的方式来交互式地完成该任务。 - Linkage analysis plays an important role in gene mapping . the foundation : the two gene locuses which locate on the same chromosomal ( eg . disease gene and marker gene ) happen to cross over and recombine . the farther the distance between two locuses is , the higher the probability happening to cross over is , the lower the probability that the two locuses are inherited to offspring together is , that is , the degree of linkage is not strong . so we can estimate the distance and the degree of linkage by the recombination fraction between the two locuses to locate gene
连锁分析是基因定位主要策略之一，其基本原理是位于同一染色体上两个基因位点(例致病基因与标记基因)在减数分裂的过程中会发生交换与重组，染色体上的两个位点间距离越远，发生重组的概率就越大，两个位点在一起传给后代的机会就越少，即连锁程度弱，这样由标记位点与疾病位点间的重组率可估算出两者间的距离以及连锁程度，达到基因定位的目的。
