his document covers the low level communication details for modbus at the data level for RS232 and other serial interfaces.

解决全局变量在编程时遇到的疑惑，值得一看。有很好的参考价值。(To resolve global variables encountered in the programming of doubt, worth a visit. Have a very good reference value.)

关于故障诊断的PPT,涉及基于模型的故障诊断,Rolf Isermann大师的杰作.(A ppt about fault diagnosis, mainly in model based fault diagnosis, authored by the well-known master,Rolf Isermann)

这是HARRIS1988年角点检测的原文。。。非常有参考价值(This is the original HARRIS1988 corner detection. . . Reference value)

说明：  The "Inductance coil" is a utility for calculation of inductance coil parameters such as length of wire which need, turns number, winding thickness, Q-factor of an oscillatory circuit with it, etc.

说明：  本文介绍MATLAB环境下上位机与下位机通过RS232接口进行串行通信的实现方法 详细叙述了在MATLAB环境下使用其自带的控制工具箱中的串口事件回调函数,实时接收下位机输出串行信号的实现过程. (This article describes the MATLAB environment, host computer and the next-bit computer through RS232 serial communication interface implementation methods described in detail in the MATLAB environment, using its own control in the toolbox serial event callback function, real-time to receive the next bit machine output string line signals the implementation process.)

关于湍流仿真的经典文献，对气象雷达和流体力学专业等相关专业的人士非常有参考价值。(The standard k-E. equations and other turbulence corrections are evaluated and reported with respect to their applicability in three-dimensional flows. The turbulence models are formulated on the assumption that an ilsotropic eddy viscosity and the modified Boussinesq hypothesis adequately describe the stress distributions, and that the source of predictive error is a consequence of the modeled terms in the ke equations. Turbulence model corrections are incorporated to investigate their impact on these errors. Predictions from various turb+lence models are compared with experimental data froq an isothermal 3-D configuration. The data combsons delineate the relative advantages and disadvantages of various modifications. The k-E model perfbrms competitively with other model corrections and in some instances is judged to be superior than the modzfied treatments. However, given the additional computational time and the marginal superiorityofthe investigated models, it is )

一套变频器完整的原理图，变频器维修的初学者可以参考一下，了解变频器的内部结构。(Completa schematica di un convertitore di frequenza, l inverter può fare riferimento al mantenimento dei principianti per capire la struttura interna del convertitore.)

求单词个数的三种算法分析 用户任意输入一个字符串 ，求该字符串中包含的单词个数 ，其 中单词以空格分隔。这道题目难度合适，不用理解复杂的概念，纯粹的考察学生解决问题的能力，而且题目看似简单，学 生很有信心能够解决这个问题。每年讲解程序语言基础课或者程序设计高级时 ，都拿这道题目让学生做练习 ，但是学生做 的情况并不乐观 ，因此有必要总结一下 3 种经典解法 ，让初学者也能够体会到程序和算法的乐趣 ，让学生爱上学习。(Find the number of words any of the three algorithms analyze user inputs a string, find the number of words contained in a string, in which words separated by spaces. This question is difficult to project the right, do not understand the complex concepts, students study the pure problem-solving skills, and the subject appears to be simple, the students are confident to solve this problem. Explain each programming language basic course or advanced programming, they all head to take the problem asks students to do exercises, but students do not optimistic, it is necessary to summarize the three kinds of classical solution, so that beginners can understand the procedures and algorithms fun for students to love learning.)
