活化添加剂促进酸矿反应的重要途径是改变硫酸钙结晶的晶习，减弱硫酸钙对磷矿包裹的致密程度，特别表现为对第二阶段的反应十分有利，而超声波对酸矿反应的促进主要表现为提高第一阶段反应的传质过程强度。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
