效能

First of all, this paper introduces the whole design project and interrelated knowledge about Non-destructive detection, ultrasonic detection, and Phased-Array ultrasonic detection Then the paper depicts the principle of Phased-Array focus and abstracts a set of math model and feasible arithmetic on the base of the real parameter of the system. Put forward several problems that exist during the course of system development and program. Introduce some measures of distinguish that are often used in non-destructive detecting and echo wave crest. Then I depict one of the measures in detail that used in the course of non-destructive detection, which is the way of distinguishing whether defects exist or not. Then provide part core program to realize it. This paper also provides main flow chart through analyzing how main control program controls different parts to make the whole system more effective.

然后在文中以较大的篇幅，描述了相控阵聚焦的原理，并根据该系统的实际参数，抽象出一套数学模型和可行的算法，在此基础上提出了在系统开发过程及编程实现过程中存在的一些问题；介绍了在无损检测中缺陷的分类和对回波峰常用的识别方法，详述了系统开发过程中使用的其中一种识别方法，即判别是否存在缺陷的算法，并给出实现之的部分核心程序；详述主控程序如何控制各部分并协调各相关软件的工作，使整个系统发挥最高效能，并给出主要设计框图和程序。
