The measurement results show that there is really a distortional boundary layer displacement surface on the ground board, and it fully differs from natural growing boundary layer on the ground board.
测量结果表明：在地板上确实存在一个畸变的附面层位移面，它与自然增长的地板附面层截然不同。

This compact meter measures both surface resistivity and resistance to ground. It is giving simple repeatable measurement of conductive static dissipative and insulative surface.
The space-wave method, suitable for extended surface targets, is a preferable method for permittivity measurement of ground materials at microwave frequencies.
