本文採用對稱拉壓循環變形方法（ r _ = _ （ min ） _ （ max ） = - 1 ） ，系統研究了織構、熱處理狀態、氫對zr - 4合金低周疲勞性能的影響， zr - 4合金、 n18合金和n36合金的循環變形行為，並研究了摩擦應力、背應力隨循環周次、塑性應變幅的變化規律。結合疲勞亞結構和疲勞斷口的分析結果，深入探討了影響合金低周疲勞行為的作用機制。 -
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。 -
Because short fibers have higher tensile resistance and ordinary concrete has higher compressive strength in the process of loading, every technical property of fiber reinforced concrete is improved greatly. accordingly steel fiber reinforced concrete has better stressing properties such as crack resistance, bending resistance, anti - fatigue, anti - friction and high toughness. so it has brilliant future in highway surface, road surface of aerodrome and architectural construction
