研究表明，即使在这种情况下，完全可以求得准确的工具面角；

The research result in the paper shows that accurate tool face angle can still be obtained under this circumstance.

因此，在调制式旋转导向工具中，就必须设置一个不受钻柱影响的、可以自动保持和调整工具面角度的稳定平台。

So, it is necessary to have a stabilized platform in the tool to obtain steady angle adjustable and independent to the rotation of drilling string.
