surface-active agent A substance that, when used in small quantities, modifies the surface properties of liquids or solids. A surface-active agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water. Surfactants are particularly useful in accomplishing the wetting or penetration of solids by aqueous liquids and serve in the manner of detergent, emulsifying, or dispersing agents. They are more effective than soap in certain situations and are used by conservators for such purposes as cleaning, wetting, and dispersing (小批量使用，用于改变液体或固体表面性质一种物质。采用表面活性剂降低表面流体或两个不混溶流体如油和水的界面张力。表面活性剂，特别是用于水的液体或固体润湿渗透有益和服务方式的洗涤剂，乳化或分散剂。他们比在某些情况下肥皂用作上述用途的清洗润湿方面更有效，且被环保专家用于此类目的的清洁、润湿和分散。) |

表面活性剂一种具有表面活性的化合物,它溶于液体特别是水中，由于在液/气表面或其他界面的优先吸附,使表面张力或界面张力显著降低。注:表面活性剂是指在其分子中至少含有一个对显著极性表面具有亲和性的基团〈以保证它在大多数情况下的水溶性〉和一个对水几乎没有亲和性的非极性基团的化合物 biăo miàn huó xìng jì | |

表面活性剂当溶于液体时，能降低溶液表面张力，提高表面活性的物质，称表面活性剂。这种物质可提高溶液表面的吸着性能,故常用于洗涤剂或乳化剂 biăo miàn huó xìng jì | |
