The results showed that when the concentration of Pb(superscript 2+) was lower than 400 mg/L, effect on the germination root length, bud length, root weight, bud weight, the root activity and the proline content of the garden balsam were not obvious.

结果表明，当Pb(上标 2+)浓度低于400mg/L时，对凤仙花种子的发芽率、发芽势、幼苗的根长、芽长、根重、芽重、根系活力及脯氨酸含量影响不大，当Pb(上标 2+)浓度为800mg/L时，对凤仙花种子才开始表现出明显的抑制作用。

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China－Lin'An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在WMO GAW 区域大气本底污染监测站－临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm（1994）和Stelson（1981）提出的方法（分别记为Malm方法和Stelson方法）重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说两种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

The gelation process of concentrated copolymer solution with different concentration of SDS was also measured.

结果表明：随着SDS浓度的增大，F127稀溶液胶束的形成受到抑制，SDS浓度愈大，形成的胶束结构就愈疏松。

Results The geometric average dust concentrations of individuals were 0.31-30.27 mg/m3,and the maximum dust concentrations of workplace were 3.13-329.3 mg/m3;the qualified rates of dust concentrations of individuals sample and the workplace were 50% and 11.1% respectively.

结果粉尘个体采样检测6个工种，粉尘浓度的几何均值为0.31~30.27 mg/m3，工种合格率为50%；定点短时间检测9个岗位，粉尘浓度最高值为3.13~329.3 mg/m3，岗位合格率为11.1%；检测噪声作业点13个，合格率92.3%。

MJ and geraniol all could inhibit the PLBs growth. With the raising of their concentration , their inhibition inhanced. MJ 100mol L-1 could inhance the accumulation of effective components in PLBs, but geraniol at different concentration inhibited the accumulation of effective components in PLBs.

MJ和牻牛儿醇均会抑制拟原球茎的生长，随着浓度的增加，这种抑制作用增强。100μmol/L~(-1)MJ可以提高拟原球茎中有效成分的积累，而不同浓度的牻牛儿醇都抑制了有效成分的积累。

In addition,the relative fresh weight and solution uptake of gerbera flowers were increased by addition of 100mgL-1 essential oil and 1 or 2mgL-1 SNP as compared to that of control flowers.

另外，相比控制培养的花朵，相对鲜重和非洲菊的溶液摄取还可通过添加进浓度为100mg/L的精油或浓度为1或2mg/L的SNP溶液来得到增加。
