运用双曲线法计算得到的沉降量大部分都大于现场实测得到的最终沉降量,但是双曲线比其他推算方法更加接近实测沉降,利用此方法计算最终沉降量对今后施工有一定的指导意义。
补充资料:C24类甾醇类
分子式:
CAS号:

性质:胆汁酸属于类甾(或固)醇类,又称为C24类甾醇类。正常人胆汁中有结合胆汁酸和游离胆汁酸两大类,并以前者为主。游离胆汁酸有胆酸、脱氧胆酸和鹅脱氧胆酸等;结合胆汁酸系指上述胆汁酸以酰胺键(简称肽键)与甘氨酸或牛磺酸结合,分别成为甘氨胆酸或牛磺胆酸等。这些化合物存在于大多数脊椎动物中,是“胆苦”的主要成分。结合胆汁酸易溶于水,这是由于其分子中既含有亲水的羟基和羧基,又含有疏水的甲基,且这两种性质不同的基团又完全排列在环戊烷多氢菲核的两侧,使分子分为“亲水”和“疏水”两个侧面。故结合胆汁酸具有强乳化剂功能,使肠腔内油脂乳化成微粒,以增加油脂与消化液中脂肪酶(lipase)接触面积而便于脂类消化吸收,同时也促进对脂溶性维生素的吸收。
