macroscopic deformation 中文意思是什麼
-
The results indicate that a stable deformation localization band occurs in the coal cutting course and develops to macroscopic crack ; the deformation localization band is slantwise ; while the cutter tooth is used, the deformation localization develops slowly, and the localization becomes wider and the strain value in the band area higher afterwards ; when the point - attack pick used the localization develops quickly and the localization band becomes narrow and the strain value in the band lower
研究表明：截齒截割煤體過程中，煤體出現穩定的變形局部化帶，且最終發展為宏觀裂紋；煤體變形局部化帶為一個傾斜帶：刀齒截割時，變形局部化發展較慢，但產生變形局部化后，局部化帶寬且帶內應變值較高；而鎬齒截割時，變形局部化發展較快，但產生局部化后，局部化帶窄且帶內應變值不如刀齒高。 -
Fractures in reservoirs are defined as macroscopic unconnectedness, which existed in rocks naturally and formed by deformation or physical diageneses
儲集層裂縫是指由變形作用或物理成巖作用形成的，在巖石中天然存在的宏觀面狀不連續。 -
It seemed that the fiber and the matrix did not creep themselves in the range of the testing stress and temperature, so the matrix microcracking and interfacial sliding will be the main contributer to the macroscopic deformation of the three - dimensional c / sic composite
由於在所測定的溫度區間和應力范圍內，碳纖維和基體本身都不大可能發生蠕變。因此，基體開裂和界面的滑動是3d - c sic復合材料宏觀變形的主要貢獻者。 -
The authors have observed the progress of deformation and destruction of coal bodies in the experiment, carried out the macroscopic and microscopic research of the destruction progress of coal samples under load by means of servo electro - hydraulic loading test and electromagnetic radiation and audio emission monitoring, analyzed the cracking rate of coal samples under different situation, investigated the formation and development of cracking by use of fracture and elasticity mechanics, and thus established a sound experimental basis for the prediction by using gray classification
摘要進行了煤體變形破壞過程實驗，利用電液壓伺服加載試驗、電磁輻射和聲發射監測手段，從宏觀、細觀、微觀三個方面對煤樣受載破裂過程進行試驗研究，分析煤樣的裂隙發展速度及其所處的不同的狀態，並參照目前的預測方法提出了煤與瓦斯突出危險狀態灰色分類方法。 -
Besides, the numerical simulation of rock failure with 5 different kinds of heterogeneities shows that the macroscopic heterogeneities affected the non - linear behavior of rock deformation and macroscopic strength as will as failure mode obviously
結果表明，巖石介質結構的宏觀非均勻性不僅對巖樣宏觀強度和宏觀變形非線性行為有顯著的影響，而且也顯著地影響試樣破裂模式。
