It proposes to adopt variable stagger arrangement and to change the horizontal tension link on push-off device into the compression link so as to reduce the deflection of contact wire in area adjacent to mid-point anchor in straight line and in large span length up to 65 m.

提出在直线区段的中心锚结附近和65m大跨距内，采取不等之字值布置法和反定位装置处的水平拉杆改成压管的措施减小接触线风偏。

Through analyzing the elite's push-off technique on curved track at 2002 world speed skating championship, it was believed that during the stroke there was an obvious difference in work mode of muscle group between the clap skates and traditional skates.
