only the last question i can t think anymore,please check the other two answers above.

Exchange rate changes

单点采用能量检测法，局限性大，于是采用多点分布式合作检测(Single point of using energy detection method, the limitations of large, so the detection of multi-point distributed cooperation)

认识共模干扰与差模干扰区别，是什么原因造成的以及怎样解决，十分有用(it is about disrupt)

该程序属于地震信号处理方面，用于估计零偏移距VSP数据中的Q值。(The program is part of the seismic signal processing for estimating the zero-offset VSP data in the Q value.)

Walsh函数产生，此程序会产生一个Walsh函数序列(Walsh function)

光伏发电模型,能实现光伏最大功率点跟踪,可以跑出仿真(Photovoltaic power generation model can realize maximum power point tracking of photovoltaic)
