pid的算法，带有自整定。还有详细的中文注释。 用户应熟知自动化工程技术，并了解闭环控制的基本原理。

本人一直使用高控件，由于使用了标准的工业接口---OPC，对于硬件的要求非常灵活，可以连接众多的PLC等智能设备。另外，不要程序员自己对于繁琐的通讯协议，更不需要书写太多的通讯代码。。。。。。。。。。。。。。

算两个整数相除,可以算到小数点后无穷位.用的是数组.可以看一下-count two integer eliminate, to be counted after the decimal point infinite spaces. Use the array. Can look at the

资源描述 C4.5算法与其它分类算法如统计方法、神经网络等比较起来有如下优点：产生的分类规则易于理解，准确率较高。其缺点是：在构造树的过程中，需要对数据集进行多次的顺序扫描和排序，因而导致算法的低效。此外，C4.5只适合于能够驻留于内存的数据集，当训练集大得无法在内存容纳时程序无法运行。

这是获得高速查找一个有效的方法。你可以在10万条记录中的1微秒的数据

One of the world-wide cooperative computing tasks is the "Grand Internet Mersenne Prime Search" -- GIMPS -- striving to find ever-larger prime numbers by examining a particular category of such numbers. A Mersenne number is defined as a number of the form (2p–1), where p is a prime number -- a number divisible only by one and itself. (A number that can be divided by numbers other than itself and one are called "composite" numbers, and each of these can be uniquely represented by the prime numbers that can be multiplied together to generate the composite number — referred to as its prime factors.) Initially it looks as though the Mersenne numbers are all primes. Prime Corresponding Mersenne Number 2 4–1 = 3 -- prime 3 8–1 = 7
