The critical micelle concentrations (CMC) and the micelle-forming enthalpies ((Hmic) of gemini surfactants were first measured by the precise titration microcalorimetry. The results showed that (Hmic values are negative, and there is an exothermal minimum between s=4 and s=6. Furthermore, the CMCs of the surfactants are in good agreement with literature values. The critical linear micelle concentrations (CMC) and the micelle-forming enthalpies ((Hmic) of gemini surfactants were first measured by the precise titration microcalorimetry. The results showed that (Hmic values ​​are negative, and there is an exothermal minimum between s = 4 and s = 6. Furthermore, the CMCs of the surfactants are in good agreement with literature values.

在张国立的影视作品谱系里,《赎罪门》是一个特别的存在,它的涉案元素,给张国立饰演马德庆形象带来了一些陌生感,毕竟观众已经适应了张国立的皇上或家庭妇男角色,出演一名经侦警察,张国立算是尝试挣脱既有形象的束缚。  在《赎罪门》里,马德庆更多时候也不是以权力人物出现的,当他便装的时候,仍然是一位个性温和、思维传统的大哥,穿上警服,也非六亲不认的那种,让马德庆承受职责与亲情发生冲突带来的撕裂感,当是电视剧
