Ti-Si composite materials are mixed at atomic scale, and Ti-O-Si bond appears in all of the samples with different TiO2 content; the mixed oxides are mainly existed in the form of amorphous pattern, anatase appears when the TiO2 content is more than 80%, but compared with the intension of pure TiO2, it has not integrate structure. The acetic content has great influence in the specific area and crystal structure of the mixed oxides. 20TiSi has good heat stability, still possesses 11m2/g after calcined at 1100℃; calcinations on the large scale of temperature does not cause the break of Ti-O-Si bond, TiO2 is well dispersed in 20TiSi calcined at 1100℃, and it still existed in the form of amorphous.
结果表明:制得的Ti-Si复合氧化物具有很高的比表面积,在TiO_2含量为10%时达到681.5m~2/g,Ti原子进入Si-O四面体结构中,形成Si-O-Ti键,复合氧化物的稳定性好,当TiO_2含量低于60 wt%时,以无定型形式存在;当含量为80%时,出现锐钛矿型TiO_2,但与纯TiO_2相比晶型不完整:醋酸对Ti-Si复合氧化物的比表面积、晶型都有很大的影响;TiO_2含量为20%的20TiSi经1100℃高温焙烧后,仍有较高的比表面积(11m~2/g),稳定性好,在较宽的温度范围内焙烧,没有引起Ti-O-Si键的断裂,分散度高,没有出现晶型TiO_2。

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.
