By means of contact test with a reference electrode underground, we measured the distribution of casing protection potential along vertical depth.

采用地下参比电极“接触测试”法，对套管实施保护后的纵向深度套管保护电位进行定量测试。

Through the comparison of various electrochemical protection testing techniques, we find that it is the most accurate in protective electric potential of the casing.

通过对比各种电化学保护测试法，介绍了接触测试法在对套管保护电位测量中的应用。

The results show that stable abnormal natural potential appeared in the steel casing indeed, and good corresponding rela…

结果表明，钢套管内确有稳定的自然电位异常显示，且异常层位与水淹层有较好的对应关系。

Microsoft certainly has its basket full with peace disturbance complaints and even a potential doubleshot casing dispute with Apple -- perhaps distracting it from properly integrating Zune TV show uploads with Media Center.

ENGADGET: ZuneTVWatcher beta to bridge Media Center gap
