第一节 引言 ◼ 定义：不溶于水而溶于有机溶剂的疏水性化合物，是脂肪组织的主要成分 ◼ 99%的植物和动物脂类是脂肪酸甘油酯 ◼ 习惯上称的脂和油是根椐其在室温下的物理状态而来的 ➢脂：室温下为固体 ➢油：室温下为液体 ◼ 提供热量和必需脂肪酸、改善食品口味 第二节 命名 第三节 脂的分类 ◼ 简单脂类 ➢酰基甘油： ➢蜡：长链醇+长链脂肪酸 ◼ 复合脂类： ◼ 衍生脂类 ➢类胡萝卜素、类固醇、脂溶性维生素 第四节 结构与物理性质 第五节 乳状液与乳化剂 ◼ 分散相，非连续相 ◼ 分散介质，连续相 ◼ 水包油体系，O/W ➢稀奶油，乳，冰淇淋 ◼ 油包水体系，W/O➢奶油 第六节 化学性质

前面,我们已经了解到,在假设检验中使用的逻辑是: 如果原假设H是对的,那么衡量差异 大小的某个统计量落入区域W(拒绝域)是 个小概率事件.如果该统计量的实测值落入 W,也就是说,H成立下的小概率事件发 生了,那么就认为H不可信而否定它.否则 我们就不能否定HO

一、填空(20分) 1.热力学第一定律可以写成△U=Q-W和△U=Q+W,产生这种差别的原因是对于有理想气体参与的化学反应,则△H△U(填“>”、“=”或“<

◼ Abortion is termination of pregnancy before 28 weeks of gestation and the fetal weight is less tan 1000g. ◼ Abortion : spontaneous: 10%~18% artificial ◼ The early abortion: occurs before 12w ◼ The late abortion: occurs after 12w

有世界坐标系(WCS):图标中有“W\,表 示当前坐标系为WCS。这是系统的缺省设置 用户坐标系(UCS):图标中没有“W”,表示 当前坐标系为UCS. .三维坐标:这是一种固定坐标系
