The results show that a large velocity gradient emerges in the intermeshing region of the screw reactors, which is helpful to mix materials sufficiently. 結果表明，螺桿反應器的嚙合區具有較大的速度梯度，有利于物料的充分混合。
Then the authors explain hypostasis of the velocity gradient and vortex, and make a try to unify the vortex coagulation theory and the conventional coagulation theory. 從根源上解釋了紊流流場(chǎng)中速度梯度和旋渦的產(chǎn)生，試圖把最近發(fā)展的渦旋混凝理論與傳統的混凝理論進(jìn)行統一。
