1·The device does not work in an oil immersion environment and has the advantages of reliable operation, convenient maintenance and stable running.

该装置不在油浸环境中工作，具有使 用可靠、便于维修、运行平稳等优点。

2·By oil immersion coupling. the system can be used to detect near surface defects with focussing probe. find surface cracks with surface wave probe and determine defect size with computerized C-scan.

该装置采用全油浸耦合，用聚束探头检测近表面缺陷，用表面波检测表面裂纹，用计算机化c扫描定量缺陷尺寸。

3·With increasing of immersion time, when the potential of thin oil film reached most positive value, it began to shift negatively.

当浸泡一段时间后，薄层油膜的电位开始随时间变化发生负移。

4·The utility model discloses a hanging immersion-type high-viscosity oil pump which belongs to oil exploration equipment in petroleum mechanical exploration field.

本实用新型公开了一种悬挂浸入式抽稠油泵，属于石油行业机械开采采油设备。

5·Results of brine immersion test, co_2-saturated brine immersion test, salt spary test and so on showed that TY oil has good multiple antirust performance.

利用诸性能评定试验初步评定了该油品的防锈性能，结果表明TY防锈油具有较好的综合防锈性能。
