The results showed that all of the four preservatives can prevent the growth of bacteroidal soft rot, and the effect of sodium diacetate was the best. After 40 or 45 days' storage, all of the untreated asparagus were rotting, but the incidence of disease of the asparagus treated with 1.5% sodium diacetate was 0 and 32% respectively. 0.5% Zhongshengjunsu, 1.5% sodium diacetate and 1% sodium chloride can delay the reduce of chlorophyll.

结果表明，4种防腐保鲜液浸蘸笋尖均可明显地抑制贮藏过程中芦笋软腐病的发生，但以双乙酸钠处理效果最好，贮藏至40d\45d，对照已全部发病，而用1.5%双乙酸钠处理的，发病率为0和32%。0.5%中生菌素、1.5%的双乙酸钠和1%氯化钠处理，均有延缓芦笋叶绿素分解的作用。

The stress resistance of common roof garden plants, e.g. Dahlia hybrida, Callistephus chinensis, Calendula officinalis and Chrysanthemum multicaule were determined by mensurating such index as chlorophyll content, electrolyte leakage, water content, Pro content, MDA content and dissoluble sugar content. The result indicates that Dahlia hybrida is the best, Callistephus chinensis next, Calendula officinalis and Chrysanthemum multicaule are weaker as to drought resistance;while in the experiment on coldness resistance, the ability to bear coldness ranks from the best to the worst is Poa annua, Festuca arundinacea and Trifolium.

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
