This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

本文用&Y&形嗅觉仪法和培养皿法测试了山楂叶螨Tetranychus viennenis Zacher对不同植物气味物质的嗅觉反应，并利用固相微萃取SPME吸附、用气相色谱—质谱联用仪GC-MS(gas chromatograph-mass spectrometer)分析了不同植物叶片的挥发性物质成分：同时采用海绵水盘法饲养山楂叶螨，研究了不同植物对山楂叶螨生长发育的影响，并测定了不同植物叶片中一些生化物质的相对含量。

By the nucleophilic substitution reaction of 6-O-tosyl-l,2:3,4-di-O- isopropylidene-a-Z-galactopyranose (3) with some substituted 1, 2,4- triazole-3-thiols (4a ~ 4c) or 1, 2, 3,4-tetrazole-5-thiols (5a~5f), nine 6-S-(substituted triazolyl or tetrazolyl)-l,2 : 3,4-di-O- isopropylidene-a-D-galactopyranoses (6a ~ 6i) were prepared in high yields.

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。
