在採用短傳方式時，一隻球隊會嘗試通過串聯一系列敏銳的短傳建立大部分的進攻，而球員不斷移動以創造或者找到接球的空間。 -
2, the friction coefficient at the pitch point is not a monotonic quantity of the rational speed or the load, instead of having a maximum value. and the value of the friction coefficient is very small, its order of magnitude only being 10 - 3. so, it is reasonable that the friction force on teeth surfaces are ignored when the gear - driven contact fatigue strength is designed
2 、當輪齒在節點嚙合時，隨著轉速或載荷的變化，齒面摩擦系數並非呈單調變化，而是存在極值點;節點嚙合處的齒面摩擦系數很小，其數量級為10一， ，因此在做齒輪強度設計時，忽略齒面摩擦力的影響是有理論根據的。
