adjacent pitch error的用法和样例：
- Obliquity caused by engaged deviation and cumulative pitch error are two mostly factor which cause gear side clearance asymmetry.
- This study is proposed to measure the straightness error, yaw error, pitch error of motion stage by using Quad Detector and Laser Doppler Displacement Meter.
- The experimental results show that the pitch error of the workpiece is decreased by more than 80%, thus significantly improving the grinding precision of the leadscrew.
- Errors of tooth-to- tooth affect the precision of gear wheels moving placidity, which mainly come from total profile error and base pitch error.
