This study provided some new evidences for the phylogenetic relationships of Rhopalocera butterflies and its subgroup Papilioninae through the primary and secondary structure analyses of 16S rRNA gene sequence, aiming at setting up a more scientific and reasonable systematics category for the butterflies, especially for those distributed in our country.

本研究通过对凤蝶亚科以及蝶类各主要类群的16S rRNA基因序列的一级和二级结构的系统学分析，旨在为蝶类的系统分类和系统演化研究提供一些分子佐证，为进一步建立一个更为科学的自然分类系统提供部分相关基础资料。

Kinetics characteristics of α- pinene isomerization catalyzed by activated carbon supported phosphotungstic acid was studied .

研究了活性炭固载磷钨酸催化α－蒎烯的异构化反应的动力学特征，研究表明，以环己烷作溶剂，α－蒎烯在活性炭固载磷钨酸上的异构化服从准一级动力学模型，其反应的表观活化能为100。

The concentrations of petroleum in photolytic processes were analyzed by UV-Vis.

结果表明，石油在土壤表面上的光化学降解行为符合准一级反应动力学，实验测得石油的光解速率常数为0.002 6-0.017 2 h^-1，半衰期为

We found that CTC in chicken feces were nearly seldom degraded in photophobic condition.After 15 days, the degradntion rate of CTC at three different concentrations was 5.93％, 7.36％, 6.20％,respectively. But under the natural illumination, the degradation of CTC in chicken feces was very fast.After 15 days, the degradation rate of CTC at three different concentrations was 98.62％, 89.53％,95.98％, respectively.

在避光条件下鸡粪中的金霉素都比较稳定，经过15d的降解，三个不同初始浓度的药物降解幅度分别为：5.93％、6.20％和7.36％；而在自然光照条件下，鸡粪中金霉素降解都较快，在15d的试验期内，降幅达到89.53％、95.98％和98.62％，将鸡粪中金霉素浓度随时间的变化趋势进行曲线拟合，可知这种变化趋势符合一级动力学方程Ct=C_0e~。

燃烧过程中产生的烟灰中含有一定浓度的PAH，在模拟太阳光中的UV-B部分的照射下，烟灰表面的PAH的光解符合一级动力学方程，而烟灰内部的PAH比较稳定，难以光解。

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.
