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.

A design and implementation method of the high speed modulation system, which adopted the new techniques of the FPGA and DAC based communication system,is presented in this paper. The effect of the key techniques of this system, such as the high speed digital signal processing for modulation, high speed based-band signal conversion, wide-band modulation, carrier suppression, high frequency and high precision system clock generation, is analyzed, and the solutions and performance analysis is also given. Finally, a high speed modulation system for space applications is implemented, can be used for high speed data transmission with QPSK, 8PSK, QAM or other kinds of digital modulation.

The dissertation analyzed the characteristic of the development of new high-tech industry at first. It pointed out that having characteristics such as high innovation and high risk, decides that the development of new high-tech industry needs the interference of government. Then, it analyzed the relevant theory of government economic functions and the particularity of the study during the development of new high-tech industry, pointed out the new high-tech industry even needs moderate interferes and supports of government. After that, draw lessons from the analysis train of the "diamond" theory of Michel Porter, it analyzed the demands of the development of new high-tech industry from the angle of catching up, include the regulation function that the key element disposes, demand regulation and preferential policy, strategical planning and organization coordinates, new high-tech enterprise hatches, and the supply of the legal system. Then it carried on international comparative analysis to the government economic functions of some typical countries, to find out the successful experiences with the lessons of the failure.
