润滑油品常用技术术语中英文对照

Acid Number(AN)Milligrams of KOH required in tests to neutralize all the acidic constituents present in a l g sample of a petroleum product.Also formally called the Neutralization Number,this property is often used to indicate the extent of contamination or oxidation of used oils.

酸值(AN)也称中和值，指中和1克油品试样中所有酸性物质所需氢氧化钾的毫克数。该性能指标通常用于表小已用过的油被污染和被氧化的程度。

Additive Any material that is incorporated into a product at relatively low concentration to impart new properties or enhance existing properties.

添加剂以相对较低的浓度加入某一产品中，从而赋予该产品某种新的性能，或者增强其现有性能的任何材料．均称为添加剂。

Aniline point the minimum temperature for complete miscibility of equal volumes of aniline and the sample under test．Products containing aromatics or naphthenes have lower aniline points than products containing paraffins.

苯胺点指相同体积的苯胺与试样达到完全混溶所需的最低温度。含有芳烃和环烷烃的产品比含有石蜡的产品的苯胺点相对要低。

Antiwear(AW)Agent Additive that is active in preventing damage caused by occurrence of solid phase welding between sliding surfaces without local surface melting.

抗磨(AW)添加剂相互滑动的表面因发生相互摩擦会造成损坏。抗磨添加剂就是能有效防止这类磨损，同时又不会令发生滑动的表面熔化的添加剂。

API Service Classification-A system of letter designations agreed On by API,SAE and ASTM to define broad classes of engine service.Also a system of service classifications for automotive gear lubricants．

API适用级别分类由API、SAE和ASTM共同商定并使用的一套英文字母代号，用以确定发动机油的主要适用级别，以及汽车变速箱润滑油的适用级别。

Aromatic A hydrocarbon derived from，or characterized by the presence of the benzene ring。

芳烃由苯环衍生出的、或因含有苯环而具有其特性的烃化物。

Bactericide Chemical compound which has the property of killing bacteria.

杀菌剂具有杀死细菌作用的化合物。

Base Number(BN)Quantity of hydrochloric(ASTM D974)or perchloric(ASTM D2896)acid expressed in milligrams of KOH equivalent that is required to neutralize all the basic constituents of a l g sample of a petroleum product.This property is used to indicate the capacity of an oil to counter the corrosive effects of acidic products of combustion.碱值(BN)中和存在于l克油品试样中全部碱组分所需要的盐酸(ASTM D974)或高氯酸(ASTM D2896)的数量．以相当的氢氧化钾毫克数表示。该性能用于表示油品抵抗酸性燃烧产物腐蚀作用的能力。

Bright Stock Refined．High viscosity lubricating oil usually made from residual stocks by suitable treatment，such as a combination of acid treatment or solvent extraction with dewaxing or clay finishing．

光亮油通常由渣油经加工处理而制成的精炼、高粘度润滑油。加工处理的方式包括：酸处理(或溶剂萃取)与脱蜡(或粘土精制)相结合。

Carbon Residue Standardized test which measures the amount of carbon left behind after pyrolysis under standard conditions

残炭用于在标准条件下，测定油品裂解后剩余碳量的标准化测试方法。

Cleveland Open Cup(coc)Tester Apparatus used to detemine the flash and fire points of most petroleum products with flash points above79℃．

克利夫兰开口杯(coc)测定器用于测定闪点高于79℃的大多数油品闪点和燃点的装置。Cloud point Temperature at which a noticeable cloud of crystals or other solid material appears when a sample is cooled under prescribed conditions

浊点在规定条件下，当油样冷却至产生明显雾状时的温度。(产生雾状是由于有晶体形成或其他固态物质生成)

Complex Grease A lubricating grease thickened by a complex soap consisting of a normal soap and a complexing agent.The use of soap complexes gives products which have higher dropping points than similar lubricants made from normal soaps.

复合润滑脂指用复合皂(即由普通皂与复合剂组成)进行稠化制成的润滑脂。使用复合皂制成的润滑脂与使用普通皂制成的同类润滑脂相比，具有更高的滴点。

Defoamants(Foam Inhibitor)Additive used in lubricating oils to assist the collapse of surface layers of foam caused by agitation of the release of entrained or entrapped air．
