solution, suspension, colloid & emulsion之间的区别是不英文本身,而在于这些概念本身,这些应该是在化学课上学的。现简单解释如下:
solution,溶液,一种化合物以分子形式分散到另一种液态化合物中,是一种均匀的混合物;
suspension, 悬浮液,一种固体分散到另一种液体中,固化以小颗粒形式与液体混合,静置一段时间后,会发生固液分离;
colloid,胶体,一种均匀混合物,在胶体中含有两种不同状态的物质,一种分散,另一种连续
emulsion,乳液,一种不溶于水的液体分散到水中,类似于悬浮液,但悬浮液是一种固体与一种液体的混合物,乳液是两种不互溶的液体的混合物
(好就请采纳。)追问对,就是化学课上学的……那么胶体的两种状态是什么意思呢?discrete, continuous 指是什么
追答在两相系统中,其中一相由分得很细的粒子(通常在胶体大小范围)组成,分布于整个大物质间,粒子称分散相或称内相而大物质称作连续相或称外相。在自然条件下这种分布通常不均匀,但在控制下可以增进均匀度。方法是加入润湿剂或分散剂(界面活性剂)例如脂肪酸。不同的可能系统有:气体/固体(泡沫塑胶);液体/气体(雾);气体/液体(泡沫);固体/气体(烟雾);液体/液体(乳化);固体/液体(漆);及固体/固体(炭黑在橡胶中)。有些形式,例如牛乳及橡胶浆的稳定是借保护胶体的附着涂膜防止分散粒子的集结。固体在液体中的胶体分散(不严格地称溶液)可经由加入电解质中和粒子上的电荷而将其沉淀下来。较大颗粒会逐渐集结上升或下沉则视其密度而定。

1. solution
[C, U] liquid in which sth is dissolved; state of being dissolved 溶液; 溶解状态: a solution of salt in water 盐的水溶液 * salt in solution 溶解状态的盐.
[U] process of dissolving a solid or a gas in liquid 溶解过程: the solution of sugar in tea 糖在茶中的溶解.
2. suspension
[C, U] (state of a) liquid containing tiny particles of solid matter floating in it 悬浮(液): medicine in powder form held in suspension, ie to be taken by drinking 药粉悬浮剂(口服用).
3. colloid 胶体; 胶质
4. emulsion n [C, U]
creamy liquid in which particles of oil or fat are evenly distributed 乳状液.
medicine or paint in this form 乳剂; 乳漆: [attrib 作定语] emulsion paint, ie paint that has a matt rather than a glossy finish when dry 乳状漆(乾後无光泽的漆).
light-sensitive substance on the surface of photographic film 感光乳剂.
无法区别的时候,就用英文解释英文。
