The principle and experiments on the measurement of grease stain in petroleum pipeline using the thermal neutron gauge were reported.

叙述了利用热中子透射计测石油管道内油垢厚度的原理、实验和结论。

mining steel rope needs eliminating oil & grease stain to fulfil meet its using requirements and extend its service life.

为了满足矿用钢丝绳的使用要求，延长其使用寿命，需要对其除油除垢。

Experimental results indicate that the thickness response of grease stain is sensitive and the thermal insulating layer has no too much effect on the obtained results.

测量结果表明：油垢厚度响应曲线是灵敏的，保温层对测量结果影响不大。

tom: look, there is a large grease stain. i'm afraid that it won't come off.

汤姆：你看这一片都是油渍，我担心它洗不掉。
