拉伸與擠壓 的英文怎麼說
中文拼音 [lāshēnyǔjǐyā]
拉伸與擠壓
英文
stretch and squeeze-
Distant effect of jurassic collisions of qiangtang terrane, lasa terrane and paleo - pacific land onto the eurasian land made east qinling - dabie mountains in a compressional circumstance for a long time, and suppressed its orogenic extension ; whereas, cretaceous late - collisional extension and appearance of west pacific trench - arc - basin system relieved east qinling - dabie mountains of external compression, instantly result in violent orogenic lithosphere delamination - extension and depressurized - calefactive melting, and consequently, led to the formation of large scale early cretaceous granitoids and intermediate - acidic volcanic rocks
羌塘地體拉薩地體和西太平洋古陸在侏羅紀與歐亞大陸拼貼碰撞的遠距離效應使東秦嶺大別造山帶長期處于擠壓環境，伸展作用被抑制白堊紀的碰撞晚期伸展和西太平洋溝弧盆體系的遠距離效應使東秦嶺大別地區的外部擠壓消失，導致造山帶巖石圈迅速強烈拆沉伸展和減壓增溫熔融，從而形成大規模早白堊世花崗巖類和中酸性火山巖。In this paper, the microstructure changes of polypropylene induced by a complex combination of shearing, compression, stretching and friction actions during single pan - milling or co - milling with iron, uhmwpe and waste tire rubber chips ( wtr ) were studied and the stress induced effects were revealed. the structure and morphological development of iron particulates and wtr during pan - milling and co - milling with polypropylene were also characterized. the properties of pp / fe, pp / wtr and pp / wtr / fe composites prepared through pan - milling techniques were investigated
本文利用磨盤型力化學反應器對被碾磨材料施加強大的剪切、環向應力、擠壓、拉伸和摩擦作用，研究聚丙烯碾磨和共碾磨粉碎過程微觀形態結構和性能的變化，以及聚合物在碾磨過程中呈現的力化學現象，並將其應用拓展至金屬、橡膠等體系，研究碾磨粉碎在聚丙烯鐵超微粉體的制備、高交聯密度彈性材料廢舊輪胎橡膠（ wtr ）的超微粉碎，以及pp fe ， pp wtr材料的性能與碾磨作用的關系。The process and mechanisms of slipping, exfoliation to layered graphite and compounding with polypropylene ( pp ) on nano - scale were systemically studied. the effects of shearing force field offered by pan - milling and confined environment of the exfoliated graphite on the microstructure of polypropylene, the electrical and thermal conductivities of the nanocomposites were also investigated. based on the experimental results, a modified electrical conductive model as well as thermal conductive model for polymer - based composites was proposed
利用層狀無機物（如石墨）的弱層間結構和聚合物的粘彈性特點，在磨盤碾磨剪切力場作用下，通過摩擦和拉伸形變錯位、擠壓嵌合、拉伸滑移、剪切剝離與粉碎和混合分散等過程，實現層狀無機物層間剝離和與聚合物的納米復合。The calculated value of shear force model fit well with the experimental results. it means that compare to the tensile stress during squeeze flow the shear stress can be omitted especially when the molding rat e is low and distortion rate is low
拉伸粘度模型的計算結果與實驗結果吻合得相當好表明：在合模速率不大或變形率不是很大的情形下，擠壓流動過程中剪切力相對于拉伸應力可以忽略。In addition, the electrical and thermal conductive pp / graphite composites prepared by s3c technology keep pretty good mechanical properties. this research develops the intercalation technique for nanocomposites, as well as pan - milling mechanochemistry, the electrical and thermal conductive theories of polymer based composites. the main outcomes are listed as follows : 1
研究結果表明，磨盤碾磨剪切力場實現石墨的層間剝離及與pp的納米復合是分階段完成的，是碾磨過程產生的摩擦、擠壓、拉伸和剪切應力及物料螺旋運動過程綜合作用的結果。分享友人
