fall velocity 中文意思是什麼
fall velocity
解釋
沉降速度-
The influence of the cloud droplet spectrum character and the spectrum growth and change is considered, which does not use a cut - off value for conversion from cloud water into rain water process. in the continuous coalescence equation, the particles fall velocity difference is not moved out from the integral, but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity. in the new scheme, generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included
雲中凝結核ccn的數濃度採用超幾何函數表示；雲水向雨水的自動轉換過程採用grabowski （ 1999 ）的公式，考慮了雲滴譜的特徵和發展變化對該過程的影響，而不是採用原方案給定閾值的方法描述該過程；對連續碰並方程不再將粒子落速差作為常量提出積分號外，而是直接作為粒子直徑函數在積分號內求解，這樣處理可以迴避使用粒子群的平均落速帶來的誤差；增加了霰和雪、霰和冰晶的碰並微物理過程。 -
Excessively long fall distances are required for drops of raindrop size to attain terminal velocity.
雨滴為了得到足夠的末速度必須下降很長距離。 -
This means that the fall velocity of sand particles in such suspensions will be less than in clear water.
這意味著這種懸浮物中的沙粒的沉速將比其在清水中為小。 -
The distribution of concentration still obeys the diffusion law, only the efftects of the group particle fall velocity and the dispersive force on the diffusion index z1 shall be considered
懸沙濃度分佈仍遵循擴散定律，但擴散指教z1將受到顆粒群體沉速和離散力的影響， -般為y的函數。 -
According to all the sediment peaks of 35 floods observed at each station on the downstream of xiaolangdi, it analyzes the characteristic of delayed sediment peak and establishes a regression equation between sediment peak lag time for each section of xiaolangdi, huayuankou, jiahetan, gaocun, sunkou, aishan and lijin and peak discharge, sediment concentration of the peak, flood propagation velocity and fall velocity of suspended load of the previous station, which can search, make up and extend sediment peak lag time and provide a basis for accurate forecasting on sediment peak travel time of each station on the lower yellow river
根據小浪底下游各站沙峰均滯後於洪峰的35場洪水，對沙峰滯後於洪峰的特性進行了剖析，建立了小浪底、花園口、夾河灘、高村、孫口、艾山、利津各河段沙峰滯后時間與上站洪峰流量、沙峰含沙量、洪水傳播速度、懸移質泥沙群體沉速之間的回歸方程，可以用來查補延長沙峰滯后時間，為下游各站沙峰傳播時間的準確預報提供依據。 -
The results of flume experiment indicated that, the flow velocity and froude number of the overland flow would fall with the rainfall splash intensity rose ; the flow depth and resistance coefficient would enhance with the rainfall splash intensity increased
水槽試驗結果表明：水槽槽面薄層水流流速及弗汝德數隨雨滴打擊強度的增加而降低，水深、阻力系數隨雨滴打擊強度的增加而增加。 -
Then the air distribution system of the above - mentioned hotel ' s multi - function - hall was simulated with fidap, and the indoor temperature and velocity under the preliminary option was calculated. under the half - load condition of small air - supply quantity and slow velocity, finds that the problem has arisen, which the cold jets fall too fast in summer and the air distributes layer upon layer in winter
然後應用fidap對上述旅館的多功能廳空調氣流組織初步方案進行了數值模擬計算，預測了該初步方案的室內溫度、速度分佈，發現在送風量和送風速度小的半負荷工況下，會出現夏季送風時冷射流過早下降，冬季送風時氣流分層分佈的現象。 -
South of japan, the kuroshio path of maximal velocity is outside the other three seasons in winter. in the kuroshio extension, the two points of the lee - wave also shows seasonal variabilities, and the path is most winding in summer, straight in fall
黑潮延續體最大流速主軸在西段的第一個峰處，冬季的峰值點比其它各季向東移了一個經度；第二個峰處，則以夏季彎曲最為平緩，且在155 e附近有一個向南的小彎曲路徑。 -
If the expansion is speeding up, the distant galaxy ' s velocity would fall below the predicted value
但若宇宙是在加速膨脹，遠處星系的速率則會比預期來得慢。
