Analysing ustiloxins inhibiting plant cell mitosis The inhibition experiment of growth of garlic radicle showed that there were more cells in the telophase stage in the garlic radicle dealed with culture filtrate of Ustilaginodea virens than those dealed with H2O. The cell volume of the former was bigger than that of the latter. So it seemed that ustiloxins could inhibit the cell mitosis, but not in the cell elongation.

毒素对植物细胞分裂的抑制作用分析：用大蒜根尖做抑制试验，发现用稻曲病菌培养滤液处理过的大蒜根尖呈分裂末期的细胞数目明显多于相同条件浙江大学硕士学位论文下对照的数目，抑制率为69%，且细胞明显比对照的细胞大，说明毒素抑制根尖细胞的有丝分裂，但不能抑制细胞的伸长。

By analyzing the force on a single droplet, the function of droplet velocity with time was obtained, and calculation results showed that the droplet velocity had a quick decent, and dropped to its terminal velocity in 0.6 s.

对单液滴进行受力分析，推导出了液滴运动速度与时间的关系式，并针对CO2-H2O体系计算了不同液体雾化压力下液滴速度的变化，结果表明，液滴速度衰减很快，在0.6 s内液滴趋近其终端速度。

Unsling and wash stand the silicone tube if a long time do not need, silica gel tube should be washed with water after each use.

长时间不用应取下硅胶管洗净备用，每次使用后须用 H2O 冲洗硅胶管。

The pigs were thensubjected to S-LRM (40 cm H2O airway pressure for 30 s) at normovolemia,after venesection of 20% and 40% of the blood volume, respectively.

测定在 S-LRM 之前、当时、之后的血气、呼吸系统顺应性、血管压力、心排量。

As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb2+ reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb2+与羟基形成了配合物，主要是以的形式存在而大量进入溶液，因此，尚需进一步除铅。

In the third area, Pb2 is gradually supersaturated in solution with the increase of pH value, so the Pb2 is deposited as sediment. As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb(superscript 2+) reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb(上标 2+)与羟基形成了配合物，主要是以Pb3的形式存在而大量进入溶液，因此，尚需进一步除铅。
