The acidity of HZSM-5 was due to the non-framework aluminum species, i.e., SiAl. The intensity of acid sites of HZSM-5 declined while the quantity of acid sites increased with dehydration temperature, with optimal intensity and quantity of acid sites and maximum toluene conversion of 28.2% at dehydration temperature of 400℃.

HZSM-5分子筛的酸性变化主要是由于非骨架铝物种SiAl的变化而引起，随着脱水温度的升高，HZSM-5分子筛酸中心的强度下降，但酸中心数量增加，当脱水温度为400℃时，HZSM-5分子筛的酸中心强度和数量达到最佳，甲苯转化率为28.2%。

The activity of PPO was lower than CK and POD activity was higher than CK while the titrable acidity and sugar contents had little variation.

结果显示，处理后荔枝果皮中花色素苷、类黄酮含量下降速度低于对照，PPO活性低于对照，POD活性高于对照，而果汁中可滴定酸及糖含量与对照相比无显著变化。

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。
