Seventeen resins were selected to compare their performances in adsorbing and desorbing monosubstituent in the mixture. Experimental results showed that HZ-841 resin possessed higher selectivity and desorption capacity.

比较了17种树脂对β-环糊精单甲苯磺酰化产物的吸附特性，确定了大孔弱极性吸附树脂HZ-841对单取代物具有较高的吸附选择性和良好的脱附性能。

Zinc diamyl dithiocarbamate antioxidant showed good synergism with antimony diakyl dithiocarbamate antiwear additive in improving the oxidation stability of modified soybean oils. The incipient oxidation temperature and induction period time of genetically modified soybean oils were improved significantly by adding polyalphaolefin and additives, and they were even better than that of the synthetic base oil PAO with the same additive formulation.

结果表明，改性大豆油的不饱和脂肪酸含量越高，其氧化安定性越差；抗氧剂二戊基二硫代氨基甲酸锌和抗磨剂二烷基二硫代氨基甲酸锑在改性大豆油中均表现出了良好的抗氧协同性能，尤其在基因改性大豆油中，聚-α-烯烃和添加剂的复配使其起始氧化温度和氧化诱导时间均超过了相同配方的聚-α-烯烃油样。

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。
