階地寬度 的英文怎麼說
中文拼音 [jiēdekuāndù]
階地寬度
英文
terrace width-
From the aspect of the coupling action of geological and engineering conditions, this paper analyzes their influences on high slope stability. the result shows that constructional surface, lithology, slope angle and height are the most influential factors. provided that a slope angle in a stepped slope is constant, the slope stability is very sensitive to the height / width ratios of steps, and the best design for the slope is to make the height of each step no more than one - third of the total height and the height / width ratio between 1 : 0. 2 - 0. 3
從地質與工程耦合作用出發，分析了地質因素和工程條件對高邊坡穩定性的影響，指出結構面、巖性以及坡角和坡高是邊坡穩定性的重要影響因素，在邊坡角一定的前提下臺階狀邊坡的臺階高寬比對邊坡穩定性影響山十分明顯，一般以每級臺階的高度不超過總坡高的1 / 3 ，高寬比在1 ： 0 . 2 0 . 3之間為最佳設計。From the experiments we can get a conclusion that with the characteristics of working well, sample circuit and light path, rated current error and phase error fulfilling accuracy class 0. 2, and respond speed and bandwidth superior to old electromagnetic current transducer, the hybrid current transducer we designed is practical
實驗證明，採用這種方法設計的混合式光纖電流互感器工作可靠、電路和光路簡單，比差和相差都能夠很好地滿足國標中對0 . 2級電流互感器的要求，動態響應速度、帶寬等性能都明顯優于傳統的電磁式電流互感器，已經進入實用化階段。In order to increase the energy dissipation of stepped spillway at iarge unit discharge, the integhty dissipater of aerated splitter pier and steppe characteristics is studied. because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow, the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease. in special at large unit discharge, this effect is more obvious
摻氣分流墩的增加，明顯地改善了階梯面上的壓強分佈，消除或減小了階梯凹角內和立面上部的負壓；由於摻氣分流墩使水流縱向擴散以及挑流落下后在階梯上的撞擊，使水流的摻氣濃度和消能率都得到較大的提高，降低了階梯面空蝕的可能性，特別是在大單寬流量時，這種效果更為明顯。The results of the three dimensional simulation emphatically show flow characteristics change along the spillway width and furthermore verify that the combination of k - e turbulence model with the vof model and unstructured grid can successfully simulate complex three dimensional turbulent flow on the stepped spillway
三維計算著重體現了流場沿溢洪道寬度方向的變化規律，進一步驗證了vof模型、非結構網格與卜。紊流模型相結合能夠成功地模擬三維階梯溢流壩面復雜流場。分享友人
