propagation of ultra short wave and microwave in theionosphere
a diathermy machine that uses short wave radiation as the source of heat.
The Autonmatic system of Hydrological Data Acquisition and Transmission at the BikouHydropower Station is a mixed system with 1:8 short wave and 1:2 ultrashort wave.
The trend of electronic reconnaissance in short wave is wide band reconnaissance, and channelized technology is the key of it.
The results are: 1) Ths short wave heating rate and long wave cooling rate of cloud over plateau are larger than that over plain, especially for the low clouds;
The test showed that in the region dominated by sub tropical high, short wave radiation was the main cause of the SST increase, surface warm water convergence played a secondary role.
