WPF版通讯录，实现3D效果

The Q3VM is a virtual machine used by Quake III to run the game module. The VM is a sort of sandbox to limit the damage a rogue or malicious QVM program can wreak. Though not perfect, it certainly is much safer than full access to native machine language, which could otherwise more easily allow the spread of viruses or the corruption of system resources. In addition, Q3VM programs, similar to JVM s, are write-once run-on-many-platforms (at least for which a Q3VM interpreter or compiler exists).

协同克里金插值算法，可用于各种地球物理手段的成图，地形图，高程图，电阻率分布等(Collaborative Kriging interpolation algorithm can be used for a variety of geophysical instruments to map, topographic maps, elevation maps, resistivity distribution.)

自己写的PBKDF2/HMAC-SHA256算法，里面还包含了SHA256 , HMAC-SHA256等算法实现

STM32 SPI口的应用例程，可是设置成主模式或者从模式。(STM32 SPI routine application of the mouth, but set to master mode or slave mode.)

简单的复数加减法 用gcc编写 进入dos 到当前路径 输入make可以编译代码 成功后 输入a.exe即可(simple fushu jia jian fa)

抛物方程 (PE)方法被提出用于电磁散射的计算,它可以克服这些数值方法计算时间较长或对计算机内存要求过高的问题,同时又可以克服高频近似法结果误差较大的缺陷。用有限差分解法对二维pade型宽角抛物方程进行数值求解，通过将散射目标等效为一系列线元并结合边界条件构建目标的电磁散射模型。在此基础上，研究二维旋转抛物方程方法，以解决抛物方程计算角度受限问题。
