1、⑧中目近代第一所女學(xué)滅洋大謦TJANJ『NUNlVERSITY碩士學(xué)位論文學(xué)科專業(yè)作者姓名指導(dǎo)教師筵堂王瑾至墓——墓緝豎塾堂天津大學(xué)研究生院2005年12月中文摘要為研究磁場(chǎng)對(duì)中藥制劑溶煤回收過程中液一液相平衡的影響,本文在不同磁感應(yīng)強(qiáng)度的釹鐵硼永磁場(chǎng)中,選用水、乙醇、正丁醇、乙酸丁酯等物質(zhì)進(jìn)行磁化處理,研究了磁場(chǎng)對(duì)物質(zhì)的粘度和表面張力的影響,并在磁場(chǎng)作用下,對(duì)正丁醇一水、乙酸丁酯一水、乙醇一水一苯物系的液一液相平衡進(jìn)行了研究。研究結(jié)果表明,外加磁場(chǎng)降低了乙醇、正丁醇、乙酸丁酯的粘度,以及水、乙醇、正丁醇、乙酸丁酯的表面張力,但磁化后水的粘度有所增加。
2、磁場(chǎng)的作用使正丁醇一水和乙酸丁酯一水物系的液一液相平衡發(fā)生了變化,且呈非線性波動(dòng),從整體上看,外加磁場(chǎng)使上述物系中物質(zhì)的相互溶解度增大,2#磁場(chǎng)對(duì)物系液一液相平衡的影響最大;磁場(chǎng)對(duì)乙醇一水一苯物系的相平衡影響取決于磁感應(yīng)強(qiáng)度的大小,磁化效果隨磁感應(yīng)強(qiáng)度和溶液組成的變化呈非線性波動(dòng)。本文通過對(duì)實(shí)驗(yàn)數(shù)據(jù)的回歸,提出了包含磁感應(yīng)強(qiáng)度的永磁場(chǎng)條件下的液一液相平衡方程以及磁場(chǎng)條件下粘度、表面張力的擬合方程,并對(duì)回歸結(jié)果進(jìn)行了分析,證明了方程的可靠性。本文較為系統(tǒng)地分析了分子內(nèi)部及分子間的各種作用力和磁場(chǎng)之間的關(guān)系,從力學(xué)的角度,探討了永磁場(chǎng)對(duì)液一液相平衡的影響枧
