摘要：
The paper finish infrasonic signal measurement and signal character analyzes of chemical explosion. Using the capacitive infrasound sensor to collect signal, after mean removal, atmosphere disturb removal, filter, unitary dispose, statistical theory is used to analyze the frequency character of infrasonic signals. According to the statistical conclusion the power spectrum of chemical explosion is gotten. One shallow-buried explosion will trigger two infrasonic signals, and one suspended explosion trigger one infrasonic signal, infrasonic signals' main power spectrums of chemical explosions distribute in [4 similar to 6]Hz.
