Optical mapping, by contrast, can estimate the absolute length of a genome and quickly detect differences in length and structure between two genomes.
相比较而言，光学标测则可以测量基因组的绝对长度，并快速发现两个基因组之间的长度和结构差异。
A ratio between the absolute length and the relative length is applied in rescaling an actual distance between two positions to be measured.
所述绝对长度与所述相对长度之间的比率被用于重新标度将要测量的两个位置之间的实际距离。
The total number of G-bands was reduced by 36 percent, the absolute length of chromosome complement was contracted with 25 percent when cell mitosis proceeded from prometaphase to metaphase.
有丝分裂早中期至中期两个不同时期G-带带纹总数减少36％，染色体组的绝对长度缩短25％，带数减少的幅度大于染色体长度缩短的幅度。
