deep-bed test
解釋
厚料層試驗-
Through choosing different diameter of sand granule, using fecl3 and pac as the coagulants, doing paralleled test through standard filtration column compared with referenced filtration columns ( the coarser and the finer sand granule used as filtration media separately ), the thesis investigates the correlation between the filtration behavior and the depth of the deep bed l, the diameter of the sand granule d
本文採用不同粒徑的石英砂濾料，以fecl _ 3 、 pac作為混凝劑，通過進行標準濾池與參照濾池（分別裝填細濾料、粗濾料）的平行對比試驗，研究濾料粒徑改變后，濾池過濾特性與濾池深度l 、濾料粒徑d的相關關系。 -
Over the years, hong kong has built up substantial competitive edge in its telecommunication sector given its sophisticated telecommunication infrastructure, open and competitive operating environment, deep technology diffusion in the community and its position as the global test - bed of new technologies
經過多年努力，香港的電訊業已建立了強大的競爭優勢。香港有此佳績，全賴完善的電訊基礎設施、開放競爭的經營環境、科技普及，以及作為新技術全球試點的地位。 -
We are specialized in production of a wide range of cauldron - using and pump - using machinery seal pieces, agitated drives, and development and design of a variety of non - standard seal pieces ， and fluidized - bed jet mill, inert gas protection jet mill system, on - line test intelligent jet mill system, deep - cold jet mill system, and so on
專業生產各種釜用、泵用機械密封、攪拌密封傳動裝置，以及研製、設計各種非標準密封；流化床氣流粉碎機，在線檢測氣流粉碎系統，惰性氣體保護氣流粉碎系統，深冷粉碎系統等氣流粉碎機。 -
Test results show that spur dikes aligned along a single bank in the deep water zone have more effects on the adjustment of the bed topography of the wide - shallow river than in the shallow water zone ; alignment of spur dikes along both banks can effectively adjust the planimetric position of deep - water zone ; and a reasonable widening rate of the regulation line in the estuary can readjust the variation of the average water depth along the river
試驗結果表明，在深水區的單側丁壩群對寬淺河床地形的調整作用大於淺水區；雙側丁壩群的聯合作用能調整深水區的平面位置；合理地選擇治導線的放寬率，能有效地調整深槽平均水深的沿程變化。 -
By use of the morphological coefficients of estuarine riverbed and the relevant data of the north channel of the yangtze river estuary, the widening rate of the regulation line of the north deep - water channel of the yangtze river estuary is calculated, and the calculation result is in agreement with that of the fixed bed model test
利用已有的河口河床形態系數及長江口北槽的有關數據，估算了長江口北槽深水航道治導線的放寬率，且與定床物理模型試驗值基本相符。
