粘度平均值 的英文怎麼說
中文拼音 [niándùpíngjūnzhí]
粘度平均值
英文
viscosity average-
Based on the method of limitation analysis of soil plasticity, researching from the soil arching mechanism of soil - nailing retaining, the upper limit of the critical height of soil - nailing slopes and the minimum horizontal length from coping of the potential slide surface to the edge of deep excavation are obtained through the analysis to weight of soil and vertical loading and the mechanism of soil and soli - nailing acting reciprocally
摘要基於土的塑性極限分析方法，以均質土坡為例，從土釘支護結構的準粘聚力理論出發，綜合考慮土體自重、坡頂的條形荷載，以及土釘與土體的相互作用的機理，推導出了土釘支護的臨界高度的上限值和潛在螺旋曲線滑動面在坡頂方向距基坑邊沿的最小水平距離解析表達式，可供基抗支護設計參考。Klc of j3 is higher than j2 and j1 at different temperatures, and this shows the stronger ability of j3 to resist crack expanding. two probations have been tried to explore the reasons concerning the results above, one of which is by analyzing the compositions of the three pbxs above and shows that the stronger ability of j3 to resist crack expanding is probably mainly due to the use of bonder b2, and another is by using scanning electronic microscope sem to observe the fracture face morphologies of the specimens at different temperatures. the quantitative observations strongly support the laws of klc of pbxs changes with temperature is revealed as follows : a
測試了三種高聚物粘結炸藥在不同溫度下的平面應變斷裂韌度k _ （ ic ）值，得到了這三種炸藥的平面應變斷裂隨溫度的變化規律： a 、隨著溫度的增加，高聚物粘結炸藥的平面應變斷裂韌度降低； b 、在45以後j2的平面應變斷裂韌度降低最快，在60時已很差，比j1還低，可以認為j2在高溫下的抗裂紋擴展的能力比j1還差； c 、在不同溫度下， j3的平面應變斷裂韌度比j2和j1的均高，表現出相對較強的抗裂紋擴展能力。
