Methods: A randomized, single blind controlled clinical design was used to accomplish the series clinical trials included 123 cases. The troop of gatifloxation injection with sodium chloride included 20 cases in gatifloxation group and 23 cases in ciprofloxation group; The troop of gatifloxation injection with glucose included 21 cases in gatifloxation group and 19 cases in levofloxacin group; The troop of gatifloxation pivoxil included 19 cases in gatifloxation group and 21 cases in ciprofloxation group. The antibacterial activity of clinical isolates were detected by scrips which contain gatifloxation(5ug/L), levofloxacin (5ug/L), ciprofloxation (5ug/L), spafloxation(5ug/L), cefotaxime(30ug/L), penicillin(10U/L) respectively. The MICs of sixkinds of antibiotics were detected by 2-fold agar dilution method. Result: The common data of patients in the two groups of 3 troops were similiar.

为选育赤霉病毒素含量低的小麦品种，减轻赤霉病危害，在比较了免疫亲和柱液相色谱法(DON test-HPLC)和气质联用法测定小麦中毒素含量的特点的基础上，利用两种方法对自然发病和赤霉病菌人工接种的小麦籽粒DON含量进行测定。

By using the direct distillation principle, an improved and quick method which can determine the protein content in maize, soybean meal, rapeseed meal, fish meal, wheat bran, formula feed for swine and formula feed for chicken was established. The result of the study on 142 products belonging to 7 kinds of feedstuffs in three laboratories suggested that: the DD method has fine correlation with the National Standard Method. The relative deviation of the two methods was in conform to the National Standard. The coefficient of variation between different laboratoies was lower than 3%, the coefficient of variation within single laboratory was lower than 2%.

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。
