解釋
透水邊界-
The incident wave height h1 / 3 is in the range from 0. 1m to 0. 25m, and the peak period tp in the range from 1. 0s to 2. 0s. the ratio of s / h1 / 3, which refers to the subface level of wharf deck ( s ) to the incident wave height ( h1 / 3 ), is between - 0. 1 and 0. 7. three different shore connecting types : open - piled, permeable slope with armored 1ayer of dolosse b locks and impermeable slope with armored layer of concrete plate, are set in the experiment for the research on the effects of boundary condition with different shore connecting types on the wave impact
本文的物理模型試驗在大連理工大學海岸和近海工程國家重點實驗室的大波流水槽中進行，試驗中選用的隨機波靶譜為改進的jonswap譜，入射波波高h _ （ 1 / 3 ）范圍為0 . 1m 0 . 25m ，譜峰周期t _ p范圍為1 . 0s 2 . 0s ，碼頭面板的相對凈空（碼頭面板底面距離靜水面的距離s與入射波波高h _ （ 1 / 3 ）的比值）范圍為- 0 . 1 0 . 7 ，其中s / h _ （ 1 / 3 ）為負值時表示碼頭面板底面位於靜水面以下。 -
For the scattering field caused by the finite - length conducting and permeable cylinder, the boundary condition that the normal component of electrical strength is zero in conducting medium, i. e. en = 0, was used to determine the separation constant of boundary value problem in the past
以往含有有限長導電導磁圓柱體散射場的求解，大都根據導電媒質中電場強度法向分量為零，即e _ n = 0 ，這一邊界條件來確定邊值問題中分離常數的取值。 -
The jinan spring catchment is a complicated karst water system, the following major work had been done in order to discuss the proplem of spring protection and water supply. 1. having conduced exploration, experiment and comprehensive research, the southern boundary of the jinan spring catchment is determined to be the surface water divide ( changecheng mountain ), the source of yufu river and baedasha river ; the northern one is the carbonniferous and permian strata, together with the igneous rock mass in the north of jinan, and the eastern and the western ones are dongwu and mashan faults respectively, which are weakly permeable boundaries. the total area of the spring catchment is 1486 km2
濟南泉域為一復雜的巖溶水系統，為了探討保泉供水問題，主要做了以下工作： （一）經過勘查、試驗和綜合研究確定濟南泉域邊界是：南邊界為玉符河、北大沙河源頭的地表水分水嶺（即長城嶺） ；北邊界為濟南北部的石炭、二迭系煤系地層和巖漿巖體；東、西兩側分別以弱透水的濟南東部的東塢斷裂和西部的馬山斷裂為邊界。 -
