中文拼音 [cūyāsuì]
粗壓碎
英文
coarse crushing-
Coarse material entering the mill is crushed between the ring and rollers.
進入磨機的粗料壓碎于輥和鋼環之間。Failure probability of coarse aggregates ( pfca ) could be a sample index durability evaluation of concrete in compressive strength test, where pfca was the ratio of number of total particles to which of the broken ones of coarse aggregates in the failed faces of a concrete specimen
混凝土抗壓試驗中，粗集料破碎率p _ （ fca ）可以作為混凝土耐久性的一個簡要評價指標，其定義為試件斷裂面上破碎的粗集料顆粒數與暴露的粗集料顆粒總數之比。The basin - formed mechanism, evolution model and petroliferous geological features of compresso - shear basins in the world are analyzed, by which six aspects of the features are summarized as follows : 1 ) in the compresso - shear process, the sedimentary speed of basin is high, forming thicker coarse - grained clastic rocks which normally shape good petroleum reservoir ; 2 ) the source rocks of basin tend to coming from the organic matter - enriched rocks formed in pre - compresso - shear stages, except that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in pre - compresso - shear stages, e4xcept that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in frontal of deep depression ( fore deep ) of thrust belt ; 3 ) the en echelon folds ( including anticline and fault - nose structure ) are generally as good oil traps ; 4 ) the compresso - shear process is helpful to hydrocarbon accumulation ; 5 ) it may promote the maturity and hydrocarbon - generating process of organic matte, and 6 ) the thrust belts in the surrounding areas of compresso - shear basin are favorable are favorable domains for petroleum concentration
摘要通過對世界上壓扭性盆地的成盆機制、演化模式和油氣地質特點分析，總結壓扭性盆地具有6個方面的石油地質特徵：壓扭作用期間盆地的沉積速率較高，一般形成較厚的粗碎屑沉積，它們常構成很好的油氣儲集層：盆地的烴源巖往住來自於前壓扭期砂成的富含有機質的巖石，但在強烈的壓扭作用期間，在沖斷帶的前緣深坳陷（前淵）中有可能發育深水半深水相的烴源巖；壓扭（張扭）作用期間形成的雁行式褶皺（包括背斜和斷鼻等）往住是很好的油氣圈閉；壓扭作用易於成藏；壓扭作用可以促進有機質的成熟生烴作用；壓扭性盆地的周邊沖斷帶是油氣賦存的有利部位。During my master " degree investigation, i mainly focused on the coarse - grain stratigraphy within mesozoic basins in chengde and pingquan districts, the eastern yanshan, and did systemic provenance analysis and paleo - current direction measurement and studied the relationship among basin evolution, volcanism and tectonism. then i summarized the mesozoic basin development and the coupling characters of basin and mountain. the evolution of basin and mountain in this area can be divided into several stages : the stage of compression uplift and flexural basin during the triassic through the early jurassic, the stage of structural compression - volcanism and foreland basin during the middle and late jurassic and the stage of rift basin in the cretaceous
在野外典型路線調查的基礎上，對燕山地區東段承德、平泉地區的中生代盆地中發育的粗碎屑沉積層，進行了系統的物源分析與古流測定，並在此基礎上重點剖析了盆地的發育、火山活動、構造變動三者之間的關系，總結了本區中生代盆地發育規律及盆山耦合特徵，並將盆山演化劃分為：三疊紀?早侏羅紀的構造擠壓隆升與撓曲盆地發育階段階段，中晚侏羅紀的構造擠壓?火山活動與類前陸盆地發育階段，早白堊世的拉張斷陷盆地發育階段。It is considered as the main reason that the fine silicon is easier to be pressed into the matrix and to cooperate with the matrix deformation in the machining of alloy, but the coarse silicon breaks, drops out and displaces usually during the machining, which results in strenuous friction between the tool and the work and various defects in machined surface
造成這種影響的主要原因在於細小的硅粒比較容易協同基體塑性變形和被刀具壓入切屑和已加工表面，而粗大的硅塊往往發生解理破碎、脫落和位移，直接與刀具發生強烈摩擦並使已加工表面存留許多缺陷。It is found that the great cracks on the coarse surface are initiated easily than on the smooth surface by the sem observation and the crack size obtained at the dynamic indentation experiment is bigger than at the static indentation experiment under the same load. it is showed the single crystal silicon is easier to initiate the crack and fracture under dynamic load, the single crystal silicon ’ s
然後通過sem觀察單晶硅試件表面壓痕形貌，發現粗糙表面比光滑表面容易生成大裂紋，在相同載荷作用下單晶硅材料在動態壓痕試驗得到的裂紋要大於在靜態壓痕試驗得到的裂紋，表明在動態加載條件下單晶硅材料更容易生成裂紋和破碎。Compared with natural aggregate, the accumulation density of recycled aggregate is lower, the water absorption is higher, the surface is rougher and the crush index is greater, the performance of concrete changes evidently
再生骨料與天然骨料相比，堆積密度小、吸水率高、表面粗糙且壓碎指標大，對再生混凝土性能影響明顯。分享友人
