The math problem in a fan-tan game is discussed.

有这样一个古老的数学问题。

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。

Chain-grate bed temperature field is a large inertial, nonlinear and time delays controlled system.Its math model is not easy to figure out.Three Fuzzy-PID controllers are presented in this paper based on the dynamic character of fuzzy control and the static character of PID control.They are simulated via combining fuzzy logic toolbox with Simulink.The simulation result shows that they have better characters both in dynamic and static than general PID controller.At the same time, they have better robustness...

链篦机篦床温度场是大惯量、非线性、纯滞后的系统，其数学模型具有较大的不确定性；为实现其精确控制，结合模糊控制和PID控制各自在动态响应和稳态精度上的优势，提出了三种模糊PID控制器；利用Matlab的模糊工具箱和Simulink对三种控制器和常规PID控制进行了仿真比较；仿真结果表明，三种模糊PID控制器与常规PID控制相比具有良好的控制品质和较好的适应性。

It's not really math itself that is incomplete, but any formal system that attempts to capture all the truths of mathematics in its finite set of axioms and rules.

它不是说数学本身是不完备的，而是针对任何某种尝试，试图把数学全部的真命题包括在一套有限的公理与法则里。

He is first in math in his class.

他的数学在全班第一。

D missed, so there was just English and math to do , and that seemed to fit in all right.

因此，后来就只剩下英语和数学要补习了，而那似乎是没有问题的。

And it's like math flash cards for your iPhone and two children, yeah kids developed it.

就像为您的 IPHONE 电话加了一个数学闪卡。2名儿童，是的，就是孩子开发出来的。

Math Flash Cards is a great program for children of all ages.

数学闪存卡是一个伟大的计划，为儿童不分年龄人人共享的。

Math flashcard software created to improve speed and accuracy in the areas of addition , subtraction , multiplication , and division .

数学闪卡软件创建，以改善的速度和准确性方面此外，减，乘，并记名表决。

I so flirt with you in math.

我在数学课上一直在挑逗你

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
