MIPC was photocatalytically transformed to 3,4-dihydroxyl hypnone, 2-iso-butyl phenol and acetic acid, and mineralized ultimately in oxygenated TiO2 slurries. The photocatalytic degradation processed according to first order kinetics with the apparent rate constant depending on initial concentration, light intensity and the amount of catalyst. The amount of catalyst had an optimum value (0.5g/L). The apparent rate was inversely proportional to square root of the initial concentration approximately.

MIPC能被光催化转化成3，4-二羟基苯乙酮、2-异丁基苯酚和乙酸等产物并最终被矿化，MIPC的光催化反应过程符合一级动力学规律，其表观速率常数与MIPC的起始浓度、TiO2量和光强等因素有关，MIPC降解的反应速率与入射光强成正比，与MIPC初始浓度的平方根成反比。

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。

According to the iso-intensity line roughly delineated,it is co njectured that the epicenter location should be moved 110 km to east (at 20°N, 114.1°E),and based on the statistical result of the maximum distance from the epicenter location to isoseismic line with intensityⅤ, the magnitude M S=7.1 of this earthquake determined by Xujiahui observatory in Shanghai should be more reasonable.

由大致 勾画的等烈度线图推测，其震中位置应从现定微观震中向东推移110 km(20°N，114.1°E)。参考我国6 3/4～7 1/2级地震的震中位置与V度等震线最远距离的统计结果，认为上海徐家汇观象台将该震定为7.1级是较为合理的。
