结果首次对国产加拿大一枝黄花进行了体内药理作用研究，发现加拿大一枝黄花提取物能显著延长醋酸致小鼠扭体潜伏期，减少扭体次数；但未明显提高热板法实验小鼠的痛阈值；能显著抑制浓氨水所致小鼠咳嗽潜伏期和咳嗽次数；显著增加小鼠气管的酚红排泌量；急性毒性实验表明加拿大一枝黄花提取物无明显毒性，既不引起小鼠死亡也不影响小鼠体重正常增加。

The results show that 60Co-γ ray radiation has the most remarkable effect on the degradation of organophosphorus pesticides such as fenitrothion, parathion, methyl-parathion, phorate and chlorpyrifos and the maximum degradation rates are over 85%. The degradation rates of methamidophos, acephate, malathion ,dimethoate are slightly inferior to them and the optimum degradation rates is just only 34.70%. At the same time, the contents of soluble total sugars, glucose, fructose, sucrose and total sugars in apple juice decrease unconspicuously, but the total acid content in apple juice and its color value and clarity increase. Based on a comprehensive consideration of the 60Co-γ radiation effect on the actual degradation of organophosphorus pesticides in apple juice and its main chemical and physical indexes, organophosphorous pesticides residue will be decreased to a lower level with radiation dose of about 5 kGy but the main chemical and physical indexes of export apple juice can not be affected.

结果表明： 60Co-γ射线辐照处理对苹果汁中杀螟硫磷、对硫磷、甲基对硫磷、甲拌磷、毒死蜱降解效果最为显著，最高降解率均在85%以上；对苹果汁中甲胺磷、乙酰甲胺磷、马拉硫磷和乐果的降解效果不显著，最高降解率仅为35%；在0～9 kGy辐照剂量范围内降解苹果汁中有机磷农药的同时，会使苹果汁中的可溶性固形物、葡萄糖、果糖、蔗糖及总糖含量轻微降低，苹果汁的总酸度有所增加，苹果汁的色值及透光率提高；综合分析60Co-γ射线辐照对苹果汁中有机磷农药的实际降解效果及对苹果汁主要理化指标的影响，选用5 kGy的辐照剂量已完全使苹果汁中的有机磷农药残留降低到一个很低的水平，又不会对苹果汁出口主要理化指标造成影响。

The results show that 42.86% topsoil samples are polluted by Cadmium, soil synthesis pollution index is moderate, Cadmium pollution degree of topsoil correlate with the environment of sampling sites. The results also show that exchangeable Cd, carbonate-bound Cd, organic-bound Cd and residual Cd are found in all soil samples except for Fe-Mn oxide-bound Cd. Furthermore, the concentration of exchangeable Cd and carbonate-bound Cd, both which have high biological validity, is high. Humus has a certain correlation with exchangeable Cd, organic-bound Cd and residual Cd, and has no obvious correlation with other chemical speciations. Any chemical speciation of Cd has no obvious correlation with pH and total Fe of soil samples. Cadmium in topsoil can be eluviated by acid solution, the quantity of Cadmium eluviated by redistilled water is little. With the rise of pH of eluviating solution, eluviated Cadmium quantity decrease. For the same soil sample, the lower pH value of eluviating solution is, the more fast the Cadmium is eluviated, and the more thequantity of Cadmium is eluviated.

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。
