According to "EPA Fate, Transport and Transformation Test Guidelines, OPPTS 835.3170—Shake Flask Die-Away Test" and "OECD Test Guidelines of Chemical 309", a simulated biodegradation experiment was conducted with the organic pollutant parathion-methyl. First-order biodegradation rate constants for water and sediment were -0.053 and -0.295 d-1, respectively, and half-lives were 13.1 and 2.3 d, respectively.

试验结果表明，甲基对硫磷在天然地表水中生物降解一级速率常数为：-0.053 d-1；在天然地表水沉积物中生物降解一级速率常数为：-0.295d-1；在地表水中生物降解半衰期为：13.1d；在地表水沉积物中生物降解半衰期为：2.3d。

Based on the experimental results, it could be consequentially concluded that N-methoxycarbonylation of aromatic amines was followed by the exclusive N-methylation of methyl N-aryl carbamates during the reaction process.

苯环上有钝化基团的一级芳胺反应活性比较好，获得N-甲基-N-芳基氨基甲酸甲酯的产率较高，反应时间也较短；而苯环上活化基团的存在，则会降低一级芳胺的反应活性。

Results Bulbus alkaloids easily formed molecular ions(superscript + in MS and dimerized easily in alcohol solution, which did not dimerize in acidity solution. Collision induced dissociation made these alkaloids easily lose a molecule of H2O. The MS spectra of the extracts of five Bulbu Fritillartae species indicated that the major molecular ions were similar to each other, but different varieties showed very different relative abundances of these molecular ions.

结果 在正离子一级质谱中，贝母生物碱易形成带一个正电荷的准分子离子，并且在中性醇溶液中，贝母生物碱易形成二聚体，在酸性介质中则无此现象；二级碰撞诱导解离易使贝母生物碱脱去一分子水；5种贝母对照药材的总生物碱提取液的一级电喷雾质谱图显示，主要分子离子峰基本相同，但因品种不同相对丰度差异较大。
