According to the "bridging" principle, the relationship between the hydrodynamic radius ( R_ ( h)) of molecule that can block pore throat and the radius of pore throat ( R) is: R_ ( h) 0.46R.

根据架桥原理，可对孔喉形成较稳定堵塞的聚合物分子水动力学半径（Rh）与孔喉半径（R）的关系为：Rh大于0.46R。

The impact of track block sliding on track velocity is not taken into account according to traditional arithmetic of turning radius, resulting in an inaccurate calculation result of turning radius.

转向半径的传统算法中未考虑履带滑转对履带速度的影响，使得转向半径计算结果不够准确。
