乡间的

We are travel-ing by train. Out the windows, we drink in the passing scene of cars on nearby high-ways, of children waving at a crossing, of cattle grazing on a distant hillside, of smoke pouring from a power plant, of row upon row of corn and wheat, of flatlands and val-leys, of mountains and rolling hillsides, of city skylines and village halls.

乘着火车，我们领略着窗外流动的景色：附近高速公路上奔驰的汽车、十字路口处招手的孩童、远山上吃草的牛群、源源不断地从电厂排放出的烟尘、一片片的玉米和小麦、平原与山谷、群山与绵延的丘陵、天空映衬下城市的轮廓，以及乡间的庄园宅第！

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。
