Modifications of the tube shape in a typical 3.6 · 2.1 industrial in-line tube bundle arrangement were considered initially and thus an elliptic and a drop-shaped arrangement were examined numerically and experimentally in terms of thermal and hydraulic characteristics as well as particle deposition rates.

管形的点窜在一个典范的3.6 · 2.1 工业在网上束缚的安排被以为是起首，从而椭圆和一个下拉型安排的数值查究和实行的热和水力条目特征以及粒子沉积速度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
