1、自动爬取新闻页面的信息 2、使用Python语言编写(1. Automatic crawling of news page information 2. Writing in Python Language)

说明：  PFC电路模型、PWM模型等可以用于基于PLECS的仿真(PFC circuit model, PWM model, etc.)

求取地震资料二维剖面振幅谱，并对振幅谱进行了归一化和平滑。(The amplitude spectrum of two dimensional seismic data is obtained, and the amplitude spectrum is normalized and smoothed.)

wgrib2 is not simple upgrade of wgrib for grib2 files. wgrib can slice and dice grib1 files. wgrib2 is more like four drawers of kitchen utensils as well as the microwave and blender. This kitchen miracle was done by a more developer friendly design and the contributions of many people. Some functionality include, inventory and read grib2 files create subsets create regional subsets by cookie cutter or projections export to ieee, text, binary, CSV, netcdf and mysql write of new grib2 fields parallel processing by using threads (OpenMP) parallel processing by flow-based programming fortran and C interface
