可以很好地模拟广义帕累托分布，用于极值估计分布(The generalized Pareto distribution can be well simulated,and it can be used for the distribution of the extreme value estimation.)

8051 BASED INTERFACE CCTALK PROTOCOL WITH CASHFLOW ACCEPTORS

使用白塞尔方法进行大地主题解算，正算由大地线和大地方位角计算经纬度，反算有经纬度计算大地线长度和大地方位角(Using the white Searl method to solve the geodetic problem, we calculate the longitude and latitude by the geodesic and the earth azimuth, and calculate the geodesic length and the large local angle by calculating the longitude and latitude)

GPRSim.net is a basic GPR time domain simulation tool. It is partially based in the transmission line model and allows up to ten layers to be simulated with frequencies ranging from 200 to 2000 MHz. It can be used to try out different real world survey scenarios and understand how different center frequency antennas could perform, as well as getting an idea of how the ground penetrating radar A-scan might look like in the given conditions.
