同形异义词的

Under this theoretical frame, prepositional polysemy is reduced to homonymy. The close relationships among distinct senses of the same proposition are ignored,let alone exploring the way of how the senses relate each other. Therefore, their studies can't reveal the nature of semantic extension of prepositions.

在这种理论框架下，介词的一词多义现象被看成是同形同音异义现象，同一介词间不同意义的紧密联系被忽略，更不用说，研究他们之间的意义是怎样相互联系起来的，因此他们的研究不能反映介词语义延伸的本质特征。

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。
