  1. If there is a marker on the embedding device, adjust its distance from the center of the implement as required

    如果裝有標志器，調整其與要求的安裝位置的距離。
  2. A stone marker set up on a roadside to indicate the distance in miles from a given point

    里程碑，里程標路邊所設立的石制標志，以英里指示從給定的一點到該路標的距離
  3. The new measures are a function of the genetic distance between the marker locus and a qtl. through simulations, we found that when marker allele frequencies vary across loci, the previous hwd measures are biased and not powe

    計算機模擬表明，當各標記基因頻率不同時，用以前的hwd指數精細定位會產生偏差，新的指數可以有效的進行精細定位，使用y > u和y < t的樣本的lcd的功效普遍比僅僅使用y > u的樣本的氣回，的功效高。
  4. Because these supernovae release known amounts of energy, measuring the amount of light arriving on earth serves as a convenient distance marker to any galaxy in which one is observed

    因為這些超新星釋放的能量是已知的，所以測量到達地球上的光的數量就成為一種方便的距離標識。
  5. In the linkage map of paternal parent, 74 markers distributed in ' 25 linkage groups, which covered a total length of 951. 5cm. the longest and shortest linkage group was 206. 2 cm and 7. 4cm respectively. the maternal linkage map consisted of 66 marker loci in 22 groups, which cover the map distance about 712. 7 cm

    在中國對蝦的雄性連鎖圖譜中，包含25個連鎖群共74個標記，總圖距為951 . 5cm ，最大連鎖群的長度為206 . 2cm ，最短的為7 . 4cm ，標記間的最大圖距為42 . 4cm ，最小圖距為3 . 7cm ，圖距標記間的平均距離為12 . 8cm ；雌性連鎖圖譜中，由66個標記組成的22個連鎖群所覆蓋的總圖距為712 . 7cm ，連鎖群的長度介於7 . 7cm - 128 . 2cm之間，標記間的最大圖距為28cm ，最小圖距為3 . 7cm ，圖距標記間的平均距離為10 . 7cm 。
  6. 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

    連鎖分析是基因定位主要策略之一，其基本原理是位於同一染色體上兩個基因位點（例致病基因與標記基因）在減數分裂的過程中會發生交換與重組，染色體上的兩個位點間距離越遠，發生重組的概率就越大，兩個位點在一起傳給後代的機會就越少，即連鎖程度弱，這樣由標記位點與疾病位點間的重組率可估算出兩者間的距離以及連鎖程度，達到基因定位的目的。
