同时利用常压连续流动的固定床反应器考察该催化剂对甘油制备丙烯醛的工艺条件，研究了催化剂的种类、杂多酸的负载量、反应温度等条件对反应的影响。

Both the increase of lipid peroxidation reaction rate and the shortening of the latent period were dependent on the pre-existed lipid peroxides in liposomes. Al3+ accelerated the oxidation of Fe2+ in liposomal system only when liposomes contain pre-exist peroxides. The addition of Al3+ to the liposomal suspension resulted in a marked increase of turbidity of the suspension and decrease of fluidity of the liposomes.

这可能是因为在脂质体存在的条件下，Al3＋加速了Fe2＋的氧化，且加速作用与脂质体中原先存在的过氧化物的含量有关；另一方面，Al3＋可以引起脂质体的聚集，表现为浊度的增加；测量脂质体上标记的脂肪酸自旋标记物5－ Doxyl stearic acid 的ESR 波谱发现： Al3＋降低了脂质体的膜脂的流动性。

As concerning synthesis of 2-ethylhexyl chloroacetate, effects of catalyst dosage, molar ratio of 2-ethylhexanol to chloroacetic acid, reaction time, dosage of water entrainer on esterification rate were studied.

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。
