四轴飞行器基本原理，文件讲述了四轴飞行器的一些基本知识。(Fundamentals of four axis aircraft)

1将字符串给整形变量 2字符数据与整数进行算术运算，将小写转大写 3符号常量使用 4强制类型转换 5将有符号数据传送给无符号变量(1 to 2 string variables to the plastic character data and integer arithmetic operations to be lower case to upper case 3, the constant use of symbols 4 mandatory conversion 5 data will be transmitted to the symbol variable unsigned)

非均匀傅里叶变换，处理非均匀采样数据。使图像还原度增强(Non-uniform Fourier transform, deal with non-uniform sampling data.Make the image reduction degree increased)

本设计利用现代电子技术、传感器技术等，设计出一款测量准确、简单易用，造价便宜的电子心率计。此心率计总体包括了红外心率检测电路、前端信号处理电路、控制电路和电源转换电路。并用C语言编写控制程序，实现对电路的控制。(This design uses modern electronic technology, sensor technology, etc. to design an electronic heart rate meter with accurate measurement, simple use and low cost. The heart rate meter includes infrared heart rate detection circuit, front-end signal processing circuit, control circuit and power conversion circuit. The control program is written in C language to realize the control of the circuit.)

一个比较好的ppt模板，程序员汇报的时候可以使用(A good ppt templates, programmers can use when reporting)

说明：  KDM is an open source combat log parser for Aion Online and much more than a damage meter.

这是将波动方程分解为上行波下行波的源程序 把两个源代码放在一起，运行即可了！-This is the wave equation will be decomposed into up-going wave downlink wave source source code of the two together, you can run the!

基于hill本构模型和各向同性强化的MMC 伤害准则的vumat实现(hill yield+isotropic hardening+MMC damage vumat)

说明：  北京大学地球物理反演课程的一些资料，很有用，讲一些地球物理反演的理论和方法(Geophysical inversion)
