基于压缩感知理论的recPF重构算法,recpf为最新的重构算法，比之前omp之类算法，效果更好(Based on the theory of compressed sensing reconstruction algorithm recPF )

能够进行电弧特性的仿真，对接地故障有一定的参考价值和意义(It can simulate the arc characteristics and has certain reference value and significance for ground faults.)

提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定 医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。(Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.)

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 (Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.)

异步电动机的矢量控制异步电动机是一个高阶、非线性、强耦合的多变量系统,使经典的交流电机理论和传统的控制系统分析方法不能完全适用于现代交流调速系统(Asynchronous motor vector controlled induction motor is a high-order, nonlinear, strongly coupled multivariable system, the classic theory of AC motor and control system analysis methods can not be fully applicable to the modern AC variable speed system)
