中文拼音 [niǎncā]
碾擦
英文
rub-
The wheels passed him within inches.
車子擦身而過，幾乎碾著他。The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy. xrd analyses show that when pp was co - milled with uhmwpe, crystal transformation of pp occurred, its crystallinity and crystallite size decreased, whereas, only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips, and amorphization of pp was strongly enhanced by co - milling pp with iron
採用x -射線衍射研究了聚丙烯碾磨粉碎過程微觀結構變化， uhmwpe存在下pp發生晶型轉變、結晶度降低和晶粒尺寸減小；彈性材料wtr抑制pp塑性變形，碾磨導致分子堆積有序區域膨脹，晶面間距增大，結晶度下降；剛性材料金屬鐵與pp產生強烈摩擦，加快晶粒細化，晶格破裂導致非晶化。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。Prince had lain there in the ditch since the morning ; but the place of the blood - pool was still visible in the middle of the road, though scratched and scraped over by passing vehicles
清晨以來，王子就躺在那條路邊的溝里但是路中間的一大攤血跡依然可見，盡管它被過往的車輛碾壓過磨擦過。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
