Its characteristics include that the counter force is proportional with the horizontal distance of a vertical line where BHA is offset from an open hole.

新的纠斜控制方法以减小测量点与开孔点垂线间的水平距离为目标，可以提高垂钻轨迹的垂直精度。

In order to reduce the storage requirements for the test patterns, a vertical and horizontal test data compression BIST scheme based on the test pattern generation of twisted-ring counter is proposed.

为了减少测试向量的存储需求，提出一种基于扭环计数器作为测试向量产生器的横向和竖向测试数据压缩的BIST方案。
