N-butylpyridinium chloride (BPC) and aluminum chloride-n-butylpyridinium chloride (A1C13-BPC) ionic liquids were prepared in this paper. The obtained intermediate BPC was identified by H NMR and Raman spectra. The electrochemical windows and electric conductivities of acidic, neutral and basic AlCl3-BPC ionic liquids were determined. The electrochemical window of neutral ionic liquids is the widest of the three A1C13-BPC ionic liquids. The electric conductivities are increased with increasing temperature, and can be described by Arrhenius equation. The sequence of electric conductivities can be expressed as KA > Kb > KC, where ka, kb, and KC are electric conductivities for acidic, basic and neutral AIC13-BPC ionic liquids, respectively.

目的：观察海水浸泡条件下，小鼠肺组织氧自由基的改变及超氧化物歧化酶（SOD）的防护作用。方法：选用120只小鼠，随机分组，检测其SOD活性及丙二醛（MDA）含量的变化。结果：除未注射SOD的小鼠，在海水浸泡20分钟组SOD活性稍高且无统计学意义外，其余各组SOD活性均较相应对照组低，并均有显著性差异（P﹤0.01），而MDA含量变化则相反。注射SOD小鼠浸泡不同时间后，其各时间点SOD活性均较未注
