Fluidization and Sounding Pressure Characters Experimental Research on Pulsating Fluidized Bed After verifying experimentally the Rijke type self-exciting pulsating fluidized bed combustion, under different operating conditions (different empty cross-section wind speed and inaction bed height), experimental research the oscillation characters of sounding pressure in the pulsating fluidized bed. The results indicate that the sound characters in the Rijke type self-exciting pulsating fluidized bed combustor are the same with it in the Rijke type combustor, the pressure in the combustor oscillate up and down in the sinusoidal manner and the pressure is the superposition of the multiple harmonic waves.

Results The tinnitus frequency, severity of subjective tinnitus, audiogram types and some items of function test above hearing threshold were significantly different in the five groups (P.05). Specific features of pure-tone test were found in the five groups: tinnitus frequency was low, whole- frequency hearing threshold high, audiogram even, short increment sensitivity index at 1 kHz high and tone decline at 4 kHz low in the syndrome of invasion of wind-heat; tinnitus frequency was high, high-frequency hearing loss common, audiogram abruptly descending, SISI and TD at 4 kHz high in the syndrome of liver-fire up-stirring; subjective tinnitus was loud, audiogram abruptly descending or gradually descending, SISI and 7W at 4 kHz low in the syndrome of stagnation of phlegm-fire; tinnitus frequency was high, subjective tinnitus low, audiogram markedly descending or hill-like, SISI and TD at 4 kHz high in the syndrome of kidney-essence deficiency; average hearing loss was less, audiogram irregular but abruptly descending or notched in most cases, SISI at 4 kHz low in the syndrome of weakness of spleen-stomach.
