settled bed
解釋
澄清床-
Practice during the period of four years shows : ( 1 ) settled water pond and three - stage filtration system with mechanical agitation can meet the requitments of reverse - osmosis components to the inlet water quality ; ( 2 ) it must be considered in the design that the demineralization efficiency of reverse - osmosis components will be decreased about 1 % 2 % in every year ; ( 3 ) in normal case, the outlet water from reverse - osmosis equipment shall enter into mixed bed via a decarbonator ; ( 4 ) the output capacity of the mixed bed must have a sufficient surplus, to avoid its influence on the water supply
經4年的實踐表明： （ 1 ）採用機械攪拌澄清池和三級過濾的系統，可以達到反滲透組件對進水水質的要求； （ 2 ）反滲透組件的脫鹽率每年約降低1 % 2 % ，在設計中必須考慮； （ 3 ）一般情況下，反滲透裝置的出水應經過除碳器再送入混床； （ 4 ）混床的出力必須有足夠的余量，以免影響供水。 -
I cannot express what a satisfaction it was to me, to come into my old hutch, and lye down in my hamock - bed : this little wandring journey, without settled place of abode, had been so unpleasant to me, that my own house, as i call d it to my self, was a perfect settlement to me, compar d to that ; and it rendred every thing about me so comfortable, that i resolv d i would never go a great way from it again, while it should be my lot to stay on the island
這次外出，作了一次小小的漫遊，一直居無定所，總感到不稱心。現在回到家裡，跟出門在外的生活一比，更覺得這個家確實完滿無缺，舒適安定。因此我決定，如果我命中注定要在這個島上度過餘生，以後就決不離家走太遠了。 -
Excellent correlation exists between the distribution of bottom shear stress and that of sediment types. low shear stress occurs in the central mud area ; where only fine - grained sediment can be imported by weak tidal currents. once settled into the bed, it is difficult for set the sediment into motion
中部泥區為應力低值區所在，水動力弱的中部泥區只能接受弱水動力帶來的細顆粒物質，而且這些細顆粒物質一旦沉積下來，便難以再懸浮搬運走，說明中部泥區是連續沉積細顆粒物質沉積區。
