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.

Given your daughter's fecundity and some basic arithmetic it is quite clear that you cannot simultaneously give equal shares to grandchildren and to children.

考虑到你女儿孩子多，做一些基本的算术，你就会清楚的发现，你不可能同时在孙辈和子女之间进行公平的分配。

However, taking into account the 16th and 17th centuries when European mathematicians still held the view that negative is "ridiculous number", Fibonacci's awareness of the negative undoubtedly is of great significance.4、Fibonacci's understanding of the irrational depends on the geometry, and the arithmetic of Fibonacci for square root was the tendency of algorithm.

虽他忽视二次方程之负数解，但考虑到16和17世纪，欧洲数学家仍认为负数是"荒谬的数"，斐波那契对负数的认识无疑具有重要的意义。4、斐波那契对无理数的认识有赖于几何图形，"开方法"趋于算法化。
