1·Internal gear pump is the small gear wheel, the big gear for driven wheel, in work big gear with small gear cocurrent rotation.
内啮合齿轮泵中的小齿轮是主动轮，大齿轮为从动轮，在工作时大齿轮随小齿轮同向旋转。
2·In this paper, the interphase transfers of air-water cocurrent flow at elevated pressure in wetted column are investigated.
本文研究了加压条件下空气水系统在湿壁塔内同向流动时传递行为。
3·The cocurrent shear plays the roles on thinning film thickness and enhancing heat transfer, and the countercurrent shear has inverse effect.
同向切应力具有减薄液膜厚度和增大传热系数的作用；
