Based on the ostwald - de waele equation , the leakage characteristics of power - law transmitted by helical gear pump are researched , and the leakage model of power - law in the clearence is founded , and - the velocity distributing and the leakage capacity are worked out by the boundary condition . the power loss of leakage is got through the clearence leakage capacity , and the friction power loss is attained by the velocity distributing . the mathematic calculation model 利用冪律流體本構方程,首次對聚合物流體在斜齒齒輪泵中的漏流特性進行了研究,建立冪律流體在間隙中的泄漏模型,利用邊界條件求出速度分布及泄漏量;由間隙泄漏量得到漏流損失功率,由速度分布得到流體摩擦功率損失,并得到間隙最優解的數值計算數學模型,同時給出實例及數值計算結果。

2 . a series of nanoparticles with different size can be obtained from just one reaction process based on the technology of time control and sampling in different phases as suggested by ostwald ripening theory in colloid chemistry . 3 2 .根據奧斯瓦爾德成熟理論( ostwaldripening ) ,采用時間控制、分段取樣方法,能夠在一次性生長過程中得到大小成系列分布的cds納米量子點。
