求翻译:Soil moisture sensor consists of 100MHz signal source, a coaxial transmission line and a 4-pin stainless probe. The electromagnetic waves of signal transmit to the probe along the lines. As the probe impedance and line impedance are different, the superimposition of incident waves and reflected waves forms a standing w是什么意思?![]() ![]() Soil moisture sensor consists of 100MHz signal source, a coaxial transmission line and a 4-pin stainless probe.
