酸性

The results have shown that P-RE-USY has good hydrothermal stability owing to the migration of hydroxy rare earth cation from the super cages to the sodalite cages enhanced by phosphorus addition, inhibiting the frame...

结果表明，由于磷促进了稀土离子由超笼向方钠石笼中的迁移，阻止了沸石在水热条件下的脱铝作用，从而改善了P RE USY沸石的水热稳定性；P RE USY沸石酸性分布更集中在中强酸范围，有利于发生氢转移反应，而强酸数量的降低有利于减少焦炭形成，改善了焦炭选择性。

This paper makes study on effects of several factors such as leaching time,solid liquid ratio,concentration of KBr,NaCl,and NaClO on gold leaching in acid and neutral sodium chloride solution with bromide as catalyzator and industrial sodium chlorite as oxidizer.

A complex sample containing BMP and sodium fluoride was implanted under the abdominal skin of young male Wistar rats.

在纯化的BMP中加入氟化物再植入大鼠皮下，通过比较植入物在不同植入时间的组织学变化，碱性磷酸酶、酸性磷酸酶活性及钙含量来反映BMP的生物活性。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
