磨损作用 meaning in Chinese
abrasive action
abrasive activate
wearing action
Examples
- Abrasion also abets wind erosion .
磨损作用也助长了风的侵蚀。 - Due to its complexity of the problem , the theories and experiment results obtained are discrepant , and some of them are even contrary one another . started from the influence by movement rules of small cavities and solid particles , the mechanisms of combined effect of cavitation and sand abrasion are study in this thesis from the aspect of the turbulent coherent structure near the wall . first , a dynamic equation is established for a single spherical bubble and single spherical sand under the non - turbulent coherent structure near the wall , and then a dynamic equation established under the turbulent coherent structure near the wall
首先从理论上推导出在典型湍流边界层模式的非拟序结构下空泡与固体颗粒的近壁区运动方程，然后推导出湍流近壁拟序结构作用下的空泡与固体颗粒的近壁区运动方程，再将两种不同条件下的的运动方程进行比较，指出湍流近壁区的拟序结构对空蚀与磨损的发生具有决定性的意义，即正是由于拟序猝发作用的存在，才使得空泡、沙粒对壁面的空蚀与磨损作用得以发生。
