平台大钢琴

But the piano soon reached adolescence and then developed into the Lisztian and contemporary nine- to ten-foot concert grand.

但是不久钢琴就迅猛发展，于是就发展成李斯特风格，以及同时代的九到十英尺的平台大钢琴。

Eased heavily from the box, they would sit on the desk with an air of expectancy, like a concert grand once the lid is raised.

悄然 离开箱子，带着期待着神气坐在桌子上，就像一架架刚打开盖子的平台大钢琴。

With worn, compacted, hammers, playing softly is impossible and the soft pedal has less effect in changing the tone.

这与平台琴不同，直立钢琴在柔音踏板踩下时，是无法弹出大的音量。

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。
