求翻译：观察图中各点发现各比值点都位于0.7附近。由上述分析知，在水平检测方向上，0.7倍的By峰值所对应两点位于缺陷的边沿位置，而两点间距即为缺陷长度l。是什么意思？

Observe the point found in the figure the ratio near 0.7 points are located. From the above analysis, and the levels detected on direction, 0.7 times the corresponding By Peak Point is located on the edge of the defect, and distance between these two points is a defective length l.

In the observation chart each discovery various ratios all are located nearby 0.7.By the above analysis knowledge, in the level examination direction, 0.7 time of By peak value corresponds two is located the flaw the border position, but two spacings namely for flaw length l.

Observation of a ratio of the discovery of the point are located in the vicinity of 0.7. From the above analysis of knowledge, in the direction of detecting, 0.7 times peak times By two points at the edges of the defect location and distance between two points is the defect length l.
