極大臨界值 的英文怎麼說
中文拼音 [jídàlīnjièzhí]
極大臨界值
英文
maximum critical value-
On the basis of investigations into the progressive yield process and the possible failure modes of rcc gravity dams, the quasi - elasticity design limit state of the ctrtical stability criterion is proposed and the real working state of the dams designed according to the ctriterion is discussed. a check formula using the material strength reducing factor as the safety index and a simplified formula similar to against sliding stability fromula are derived. finally, the corresponding design safety factors are given by using fem calculations with various influence parameters to be taken into account
本文在研究碾壓混凝土重力壩漸進破壞過程和可能失穩方式的基礎上，提出了以準彈性臨界作為穩定臨界準則的設計極限狀態，分析了按該準則設計的大壩的實際工作狀態，導出了以準彈性強度儲備系數為設計安全指標的審查公式以及形式與抗剪斷公式相同的簡化公式，探討了定量計算考慮各種因素影響的相應設計安全系數的合理取值，並與現行規范方法進行了比較The boundary layer can indicate the comprehensive influences of oil reservoirs, the physical properties ( reservoir porosity, permeability, fluid viscosity and its composition ) of inside fluids and development conditions such as pressure gradient : the layer thickness reduces with the rise of capillary radius ; when capillary radius is fixed, the thickness increases with viscosity rise ; the more polarity composition content is, the more obvious the absorption, the thicker the boundary layer, more and more obvious the characteristics of non - darcy filtration
邊界層反映了儲層、流體物性條件（儲層孔隙度、滲透率、流體粘度、組分）和開發條件（壓力梯度）的綜合影響，認為邊界層厚度隨著毛管半徑的增大而減小；在毛管半徑相同的情況下，邊界層厚度隨壓力梯度的增大而減小，最後達到一個臨界值；毛管半徑一定時，邊界層厚度隨粘度增加而增大；極性組分含量越大，吸附越明顯，邊界層厚度越大；邊界層厚度越大，非達西滲流特徵越明顯。Heavy precipitation often forms in the place between the source of high - disturbance wind field at 200hpa, especially of low - disturbance wind field at 850hpa. ( 2 ) the temporal and spatial scale about e - reflection index of nonlinear subcritical symmetric instability disturbance is 5 - 8hours and 200 - 300km respectively
非線性亞臨界對稱不穩定使線性對稱穩定的大氣變為不穩定。降水區和暴雨中心主要位於高層200hpa和中層500hpa擾動風場極大值南側與低層850hpa擾動風場極大值北側之間。We also obtain similar results on nearly reducible boolean matrices. we determine the maximum values of the first type of indices of convergence of n x n boolean matrices, reducible matrices, critically reducible matrices respectively, characterize the corresponding extreme matrices
對第一種類型的廣義冪斂指數，我們得到了n n布爾矩陣類， n n可約布爾矩陣類， n n臨界可約布爾矩陣類的這種指數的最大值，刻畫了極矩陣。分享友人
