 note = {The authors observed the waveforms of atmospherics in summer daytime，of which sources were in the vicinity of the station，and classified them into three fundamental types，i.e., main discharge type，leader discharge type and partial discharge type. They can be interpreted as to be radiated from the main stroke of a lightning，the stepped leader discharge and the partial discharge in the thunderclouds respectively.},
