林昌禄的天线工程手册！没的说的!希望你喜欢！(Lim Chang-lu antenna engineering handbook! Not to say that the! Hope you like!)

小波矩程序，中间感觉有点问题，但是可以用，希望对大家有帮组(Wavelet moment process can feel a little problem, but can, we want to have to help group)

计算苯、甲苯和对二甲苯混合物组分的程序，并且通过图示的形式显示出来(The program computes the composition of benzene, toluene and p-xylene versus time in all column plates. The steady state values are plotted versus the plate number for all three components. This MATLAB program is adapted from an example given in Chemical Engineering Dynamics by Ingham et al., Wiley-VCH, 2000)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)

太阳能光伏经过整流再进行并到交流电网的平台搭建(Solar photovoltaic is rectified and then built on the platform of alternating current network)

传统的决策树能较好地解决分类问题，但当类的个数增多时，所产生的单一决策树就会变得复杂，同时概括能力降低。 该文采用基于层次分解的方法通过产生多层决策树来处理多类问题。 与传统的单一决策树比较， 基于层次分解的决策树在处理多类问题时有许多的优势。(induction learning,decision tree,id3 ,hiberarchy decomposition)

this program is for on-off-keying signalling modulation.
