Finally, the values of kinematic parameters in typical swimming are estimated for theoretical calculation and computational simulation. based on the kinematic formulation, this paper applies large - amplitude elongated body theory to propulsive performance of undulatory dorsal / median fins and establishes a set of equations for estimation of the propulsive force and the propeller efficiency. the calculations based on experimental data coincide with blake ’ s result in 1980
從波動運動的參數方程出發,本文基於大擺幅伸長體理論對背鰭/背臀鰭波動模式的推進性能進行了分析,推導推進力和推進效率的計算公式,利用實驗觀測典型運動參數對仿生對象的推進力和推進效率進行了理論估算,結果與blake的計算結果相吻合,從而驗證了所建運動學模型的有效性。The experiment result shows that with low - temperature oxygen plasma treatment, fabric ' s shrinkage and wettability have bettered a great deal, and fabric ' s breaking strength and breaking elongation is also increased in given condition
有效控制處理條件,織物的斷裂強力和伸長率不但不會減小,反而可以得到一定程度的增強。Experiments show that fpmine runs two times as fast as the most recently proposed algorithm fp - growth and saves half the memory ; moreover, our algorithm has a quite good time and space scalability with the number of transactions, and has an excellent performance in dense database mining as well ; spf has excellent time and space efficiency ; fpmine - spf algorithm has a far taster speed in association rules mining than the widely used apriori algorithm and has wonderful scalability. association rules mining always generates too many rules, which makes ii difficult to pick the valuable rules where from
實驗表明,在相同數據集上,與fp - growth演算法相比,演算法fpmine的挖掘速度提高了一倍以上,而所需的存儲空間減少了一半;隨著數據庫規模的增大,演算法fpmine具有很好的可伸縮性;對于稠密數據集,本文演算法也具有良好的性能; spf演算法具有極好的時空效率; fpmine - spf演算法挖掘關聯規則的速度遠快于較長期以來廣泛使用的apriori演算法,並有相當好的可伸縮性。
