The results showed that behavior of the smog and TSP are in accordance to the formula of dynamics, changes of cresol mixed isomers' density conform with exponential function. With air disinfecting in indoor with smog, the killing percentage of Staphylococcus auras are up to 99.92% during 30 min, and that of natural bacteria is up to 99.66% during 120min, and the sm...

结果表明，烟雾及其有效成份在空气中按一定的规律沉降；并且在 30min作用时间内能够有效地杀灭空气中 99.92 %的金黄色葡萄球菌；在 12 0min内空气自然菌的平均杀灭率可达 99.66%，烟雾对室内空气环境具有一定的净化作用。

The response of plant DNA to UV-B radiation has certain sensitivity which related to UV-B radiation intensity and plant cytoplast, showed specific dose-effect relationship.

It can be concluded from there plots that vibration control of damped plates can be obtained in some range of temperature and frequency if the damped plater possess suitable thickness and appropriate viscoelastic mateial .

从这些图中可以看出：采用某种粘弹性阻尼材料和一定厚度约束层的阻尼板在一定的温度和频率范围内控制阻尼板的振动能达到满意的效果。

Field experiment showed that coating agent with uniconazole (No2 uniconazole seed-coating agent) could significantly defend cucumber seedlings agaist damping-off, inhibit vertical growth and strengthen in thickness of young seedlings. It could blossom early, significantly increase fruit numbers per plant and yields of early stage and total yield. After coating cauliflower seeds by No2 uniconazole seed-coating agent, the uniconazole coating did not affect emergence rate, reduced damping-off disease incidence, increased stem diameter and fresh weight of seedling underground parts.

大田栽培试验发现：烯效唑包衣能显著防控黄瓜苗期猝倒病，抑制瓜苗纵向生长和促进幼苗加粗，使植株开花提早，包衣后黄瓜单株结瓜数提高，前期产量和总产量均显著提高；烯效唑包衣花椰菜使其出苗时间略有延长，但对出苗率无明显影响，包衣后的幼苗猝倒病发病率显著降低，叶色明显加深，幼苗茎粗和地下部鲜重显著增加，包衣的植株现蕾期提早，花球单重显著增加且表现出一定的增产效应，但试验的两品种间存在一定的差异。

The results show that Tc and diamagnetic susceptivity decrease, crystal structure changes from being orthorhorhombic to a tetragonal system with increasing Fe and Co content.
