From the UV spectra, it can be found that the aromaticity of acenaphthenyl groups in C_2 gum is the largest. But there are 30 carbon atoms in the conjugated structure of condensed aromatics in C_1 gum and C_3 gum, while 28 carbon atoms in acenaphthenyl groups in C_2 gum.

但是，在C_1胶、C_2胶和C_3胶三者中，C_1胶侧链上的四苯基苯基和C_3胶侧链上的菲式多苯基苯基都含有30个碳原子，而C_2胶侧链上的苊式多苯基苯基含有28个碳原子，比前面二者小2个碳原子，理应其芳香性在三者之中最小，但事实却恰恰相反。

Objective TO compare the different changes of blood lactate and blood gases when given the lactated Ringer's solution and acetated sodium solution during operation. Methods 40 patients are divided equally into the lactated Ringer's group and the acetated sodium grouprandomly,adapting the combined intravenous and inhalation general anesthesia. The lactated Ringer's gis given in group L and the acetated sodium in group A. Neither groups are cross-given other crystal solution during operation, polygeline is the only colloid solution in both groups.

目的 比较术中输入乳酸钠林格液和醋酸钠林格液血乳酸盐及血气的变化方法 40例择期手术患者按随机字表随机分乳酸钠组和醋酸钠组，每组各20例，采用静吸复合全身麻醉。L组术中输入乳酸钠林格液，A组术中输入醋酸钠林格液，两组术中不交叉输入其他晶体液，输入胶体液均为菲克血隆。
