( 3 ) for parameterization of the sensible heat, the positively correlation between surface temperature and bulk transfer coefficient lead to a positive additional sub - scale flux. its magnitude is determined by the grid average roughness and average wind velocity on the reference level
（ 3 ）對區域感熱通量的計算而言，由於地表溫度和整體輸送系數產生一個正的次網格通量項，它主要由網格平均粗糙度和參考高度平均風速所決定。 -
However the cavitation effect induced by ultrasound may prematurely catalyze nucleation, which hinders the further achievement of bulk undercooling. the measured growth velocity of ice dendrite is 0. 17m / s corresponding to the maximum undercooling of 24k
討論了空化效應對水滴過冷度的影響，認為空化效應誘發水滴提前形核，抑制了大過冷度的獲得。 -
The results show that : the lose of pressure is small when air velocity and the longth of honeycomb potter heat storage bed are varied ; but the switch time of air and the bulk of storage bed play important roles as regard its dynamic thermal performance
結果表明：蜂窩型陶瓷蓄熱體換熱器的壓力損失隨著空氣流速以及蓄熱體長度的不同而變化，但總體上說，其壓力損失並不大；四通換向閥的換向周期和蜂窩陶瓷蓄熱體換熱器的體積等是影響其溫度效率和熱回收率等熱性能的重要因素。 -
Using the velocity of bulk acoustic wave and surface acoustic wave in the aluminium sheet measured by this system, elastic constants of aluminium are deduced
通過實驗檢測鋁板的超聲回波，求出了鋁的超聲波速度，並根據固體力學理論，得出了與理論數值相符合的材料的彈性模量。 -
The influences of the inlet tube angle, backpressure and driving jet velocity on static pressure distribution in the gas - solid injector are calculated, and the effects of the inlet tube angle on particle bulk phase concentration and axial mean speed of particles in the gas - solid injector are analyzed firstly. the predicament caused by lack of measuring means on the particle velocity in experiments is solved
分析了收縮角、背壓和氣體噴嘴出口速度對氣固噴射器內靜壓分佈的影響，以及收縮角對氣固噴射器內固體顆粒體積濃度場和顆粒平均速度的影響，解決了噴射器內固體顆粒速度試驗測試手段缺乏的困境。 -
