大多数胎头位置异常为持续性枕横位和枕后位，可以试产；
Majority fetus head position unusually is persistent occipitoposterior position and persistent occipitotransverse position, can trying the delivery;
结果表明：前11项旋转主分量的主要高荷载中心，与持续异常的高频数中心或其邻近区域大都基本吻合；候平均环流异常的持续性略高于马尔柯夫过程。
The results show that the localities of high-loading centers of the first 11 RPCs basically coincide with those of the high frequency regions where the persistent anomalies occur.
