| antifouling agent Agent that inhibits the growth of barnacles and other marine organisms on a ship's bottom (an antifouling paint or other coating). Organo-tin compounds have been the most often used agents in this application since they are effective against both soft and hard fouling organisms. However, in spite of their performance, they have a negative impact on the marine environment and their long half life in the environment, has prompted marine paint manufacturers to look for a nonpersistent alternative | 船底防污剂 (一种用于抑制藤壶(一种甲壳类动物)或其它海洋生物体在船舶底部生长的试剂(防腐用油漆或其它涂料)。 有机锡是最常被使用的试剂，因为它可以有效的抑制柔软和坚硬的致腐蚀性之生物的生长。 虽然它具有防污的功能，但是它对海洋环境有负面影响，且它在环境中有很长的半衰期，这促使船舶油漆生产商寻找其他非持久性的替代物。) |
| bleaching agent 1. A chemical, such as an aromatic acyl peroxide or monoperoxiphthalic acid, used to bleach flour, fats, oils and other edibles. 2. An oxidizing or reducing chemical such as sodium hypochlorite, sulfur dioxide, sodium acid sulfite, or hydrogen peroxide | 漂白剂 (1. 一种化学物质，如芳香酰基过氧化物或monoperoxiphthalic酸，用来漂白面粉，油脂，油和其他食品。 2. 一种氧化还原物，如次氯酸钠，二氧化硫，亚硫酸盐钠酸，或过氧化氢。) |
| complexing agent A substance capable of forming a complex compound with another material in solution | 助混剂 (一种能够与溶液中的其它物质形成复杂混合物的物质。) |
| fireproofing agent A chemical used as a coating for or a component of a combustible material to reduce or eliminate a tendency to burn; used with textiles, plastics, rubbers, paints, and other materials | 耐火粉饰 (一种用作涂料或可燃物中成分的化学物质，可以减少或消除燃烧的趋势；与纺织品，塑料，橡胶，涂料，和其他材料一起使用。) |
| foaming agent Substances which make it possible to form a homogenous dispersion of a gaseous phase in a liquid or solid medium | 发泡剂 (一种物质，可以在液体或固体媒介中形成连续分散气相。) |
| forwarding agent A person or business that specializes in the shipment and receiving of goods | 货运代理 (专门从事运输和货物接收的个人或企业。) |
| impregnating agent A material used to fill holes in wood, plaster, or other surfaces before applying a coating such as paint or varnish | 渗透剂 (在对木材、石膏或其他物质表面涂漆前,应注满它们表面的孔隙，注入时所用的制剂被称为渗透剂。) |
| oil binding agent Highly absorbent agents used for physically removing spilled oil in case of leakages and oil accidents occurring in water bodies, industry, work-shops, on roads, etc. Materials that have been found useful for this service vary from simple, naturally occurring materials such as straw, sawdust, and peat to synthetic agents, such as polyurethane foam and polystyrene powder | 油黏合剂 (高度吸收剂，用于完全清除石油泄漏或水体、工业、工厂、道路上等发生的石油事故的溢油。已经发现的对该服务有用的材料，来自于不同的简单和自然形成的原料，如稻草、锯末以及泥炭合成剂，如聚氨酯泡沫、聚苯乙烯粉。) |
| oxidising agent Compound that gives up oxygen easily, removes hydrogen from another compound, or attracts negative electrons | 氧化剂 (氧化合物，移除从另一个氢原子吸引得到的电子。) |
| oxidizing agent | 氧化剂 |
| photochemical agent Agents which trigger off photochemical reactions | 光化学代理 (代理，引发光化学反应。) |
| softening agent 1. A substance added to another substance to increase its softness, pliability, or plasticity. 2. A substance, such as a zeolite, for softening water | 柔软剂 (1. 一种物质添加到另一种物质，以增加其柔软性、柔韧性或可塑性。 2. 一种物质，如沸石，用于水的软化。) |
| 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 | 表面活性剂 (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。) |
