The results showed 3 types of aluminum compound prepared in this paper all had good poison protection effectiveness on such impurities as stannous chloride,lead oxide,sodium hydrogen sulfate,and so on.Moreover,the mechanism of the poison of catalyst was also discussed.

结果表明，合成的3种防中毒剂即防－1、防－2(主要成分为乙酰丙酮合铝)及防－3(主要成分为二乙酰丙酮基异丙氧基铝)对二月桂酸二丁基锡、氯化亚锡、二正丁胺、硫脲、氧化铅及硫酸氢钠等杂质均有较好的防中毒作用；不同防中毒剂对不同杂质的防中毒作用有一定的选择性。

After being oxidated for 34 h, and then the contents of Fe2+ in the 9K liquid solution with 4×10-4mol/ L xanthates, dithiophosphates and D-250 added inreased from 4.03 g/L to 4.64, 4.77 and 5.91g/L, respectively. After leaching for 35 d, the leaching rates of Zn are 92% and 61% respectively. It shows that the flotation reagents (xanthates, D-250) have great effect on the activity of bioleaching bacteria.

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。
