Gas Production Engineering Research Institute,Southwest China Oil Gas field Company,Guanghan 618300,China）Abstract: Basic principle of time of flight diffraction method was described. Two scan modes D scan and B scan were discussed and the phase characteristic of oscillogram and grey-scale map was also studied. Formula to calculate the location and size of defects was given. The image analysis was carried on three typical defects on standard blocks.

摘 要：描述了超声波衍射时差法的基本原理，讨论了平行扫查和非平行扫查两种扫查方式，研究了波形图和灰度图两种缺陷图谱的相位特征，推导了缺陷精确定位定量的计算公式，并通过标准试块试验对三种典型缺陷进行了图谱分析。

Say for example, when discussing on parallel axiom, which is "given a point and a line on a plane, there exists a unique line on the plan that passes through the point and is parallel to the line", if we change the axiom as "there is not any or there are infinitely many lines that will pass through the point and be parallel to the line", then we have two kinds of non-Euclidian geometry.

就像对于平行公理的讨论一样，干脆规定：过已知直线外一个固定点可以作无数条与已知直线平行的直线；或者过已知直线外一个固定点的任何直线都不能与已知直线平行；这样还产生了两个版本的非欧几何。

The effect of non-parallelism of stability is studied by comparing the results of parallel and nonparallel flow.
