seawater density 中文意思是什麼
-
Length, diameter, density, fresh weight, dry weight, water content, osmotic potential and element concentrations ( ca, mg, na, k, cl ) were determined for each. seedling of b. gymnorrhiza and a. corniculatum were cultured for 60 days on various salinity of seawater ( 0, 5, 10, 15, 20, 30, 40, 50 ) in green house. samples were taken at 3, 7, 11, 15, 22, 30, 45 and 60 days after planting, separated into root, hypocotyl, stem and leaf
本文研究了福建九龍江口木欖和桐花樹胎生繁殖體從果實形成到發育成熟過程中形態、生物量、含水量、胚軸密度、滲透勢、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化和溫室內人工鹽度梯度栽培下木欖和桐花樹成熟繁殖體長成幼苗（ 0 60d ）過程中形態、生物量、含水量、滲透勢、光合蒸騰特性、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化；並且在野外自然條件下，跟蹤調查不同灘塗位置下秋茄成熟繁殖體定居成活、自然死亡狀況以及測定幼苗生長過程中（ 1年）形態、生物量、含水量、光合蒸騰特性等的變化。 -
On the contrary, the density of mature hypocotyls of a. corniculatum was much higher than seawater, they tend to sinking and grow around their parent plant
桐花樹為隱胎生紅樹植物，即繁殖體在整個生長發育階段，胚軸未露出果皮之外。 -
The drought in 1963 - 64 and the general lack of water resources in the 1960 s promoted the widespread use of seawater in hong kong. after the 1960 s, it was not an easy task to change traditional methods of waste disposal, especially in districts with high population density and areas that were already fully developed. thus, large - scale implementation of the seawater flushing system began in the kowloon peninsula, at newly established housing estates
在人口密度已相當高，及市區發展已初具規模的60年代，要改變城市既有的排污系統，並不容易，因此，海水沖廁系統的建立，首先在九龍半島一些新落成的公共屋廁開展，目的是為新發展區域日常用水提供新水源。 -
In 1957, in order to save fresh water, the water authority suggested that it would install seawater flushing systems in the newly developed areas of kowloon, such as shek kip mei and li cheng uk ( resettlement areas which had high population density ). as early as 1958, the government introduced seawater - flushing mechanisms in various districts of hong kong island and kowloon
為減低淡水的需求量， 1957年水務署建議在九龍新發展地區，如石硤尾、李鄭屋村等人口稠密的徙置區，設立海水沖廁系統。海水沖廁系統於1958年開始在港九各區實施，最早發展區域為長沙灣、黃大仙、佐敦谷、觀塘、北角及柴灣。 -
Abstraction of seawater for keeping live seafood should be avoided during and after inclement weather. ( 4 ) live fish and shellfish should be kept separately in different tanks and at a stock density not causing overcrowding
應把活魚及介貝類水產動物分開放置在不同的魚缸內飼養，而在每個魚缸所飼養的活魚或介貝類水產數目不宜太多，以免過分擁擠。 -
Thus help the seedlings survive better in the flooding and saline conditions. the density of mature hypocotyls of b. gymnorrhiza was close to or lower than seawater, thus the propagules can float and be dispersed by tide
並通過主動的滲透調節，控制各種滲透調節劑和水分的輸入，使得成熟胚軸的滲透勢達到比生境中略低的一個比較合適的水平。
