moderate cracking 中文意思是什麼
moderate cracking
解釋
中等程度裂化-
2 ) to a certainty of sand percentage, concretes with moderate critical sand percentage which changed in about 36 % - 43 % were more sensitive to plastic shrinkage cracking than concretes with lower or higher sand percentage. 3 ) concrete made with lower strength grading cement was more prone to plastic shrinkage cracking than that of concrete made with higher strength grading cement
4 ）粉煤灰和硅灰對混凝土塑性收縮裂縫的影響與拌合物的實際水膠比有關，存在一個水膠比界限，在此界限之上，摻入粉煤灰或硅灰的混凝土較易開裂，在此界限之下，粉煤灰或硅灰高性能混凝土對塑性收縮裂縫具有抑制作用。 -
Are made of tempered martensite, with moderate hardness, excellent elasticity, wear - resistant, give less dust, longer recycle life, low cost, extensively used for shot peening to give residual stress in the surface layer of components for fatigue life enhancement and suppression of stress corrosion cracking and descaling and cleaning up surfaces of castings, steel parts and mechanical work - pieces prior coating
鋼丸鋼砂主要金相組織為?火馬氏體組成，具有適當的硬度良好的反彈性耐磨性粉塵少循環使用壽命長成本低等特點，廣泛應用於鑄件鋼件機加工件的表面噴塗前的表面去皮，清理。 -
Owing to the interfacial cracking which occurs under higher applied load conditions, the composite with high content of tib _ 2 phase exhibited a transition from mild wear to severe wear over the applied load range from 10 n to 80 n. under moderate applied load, increasing the sliding speed caused a decrease in wear rate and friction coefficient of the in - situ composites because the formation of a protective oxide film occurred on the sliding surface and the hardness of the subsurface layer was maintained due to reinforcement of tib2 nanoparticles in the cu matrix
隨著載荷的增加， cu -納米tib2原位復合材料的磨損率和摩擦系數增加；由於在較高載荷下發生表面開裂，高含量的tib2相增強原位復合材料發生了由輕度磨損向嚴重磨損形式的轉化。在中等載荷下由於表面保護性氧化膜的形成和基體中納米tib2相的存在使復合材料具有良好的抗軟化能力， cu -納米tib2原位復合材料的磨損率和摩擦系數隨著滑動速度的增加而下降。
