  • double : adj 1 兩倍的，加倍的。2 雙的，二重的，雙重的；對，雙，兩，復。3 雙人用的；折疊式的。4 （意義）雙...
  • drainage : n. 1. 排水，放水；排水法；逐漸流出。2. 下水道；排水設備，排水系統。3. 水系，排水區域，流域。4. 陰溝水，（排出的）污水。5. 【醫學】引流，導液（法）。
  1. The phenomena can be observed in the tests low seepage pressures can easily form passageways behind the waterproof layer if there is no drainage layer or the drainage layer is blocked in the single - shell test slab ; the waterproof layer can resist higher seepage pressure if there is no drainage layer or the drainage layer is blocked in the double - shell test slab ; the seepage water can be controlled and drained away in the drainage layer by the water proof layer only if there is unblocked drainage layer behind it in the double - shell test slab

    由試驗可見，在單層試驗板中沒有排水層或排水層不通暢時，較低的水壓就能在防水膜后形成滲流通路；在雙層試驗板中沒有排水層或排水層不通暢時，防水膜能抵抗一定程度的滲漏水壓；只有在雙層試驗板中的排水層暢通時，防水膜才能有效地將滲漏水控制在排水層中排走。
  2. Double - channel frey ' s urinary tube for closed thoracic drainage of pneumathorax

    動物實驗評價自製多功能胸腔閉式引流系統的功能
  3. Thirdly, the method to calculate the 3 - d dynamic responding of layered transversely isotropic saturated soils to an arbitrary buried source in cylindrical coordinate as well as to an arbitrary harmonious source in rectangular coordinate is presented respectively. based on biot ' s wave theory, the 3 - d wave equations in cylindrical coordinate for transversely isotropic saturated poroelastic media are transformed into a group of governing different equations with 1 - order by the fourier expanding with respect to azimuth and hankel integral transform method or by the double fourier transform method with respect to horizontal coordinates in rectangular coordinate. then, transfer matrixes within layered media are derived under the continuous conditions, drainage conditions and the boundary conditions

    基於飽和土的biot波動理論，通過fouricr變換，將橫觀各向同性飽和土三維非軸對稱波動方程轉化為一組一階常微分方程組，再經har止el變換，建立問題的狀態方程，求解狀態方程得到傳遞矩陣;利用傳遞矩陣，結合飽和層狀地基的邊界條件、排水條件及層間接觸和連續條件，首次給出層狀橫觀各向同性飽和地基在任意地展力作用下的三維非軸對稱動力響應的解析解。
