结果 醋酸铅染毒组雄性小鼠的生殖腺有不同程度的病理学改变，精子计数、直线运动精子数、活精子率下降，而静止不动精子数、精子畸形率和初级精母细胞染色体畸变率升高；海尔福治疗组小鼠的生殖腺病理学改变有不同程度的改善，精子计数、直线运动精子数、活精子率有所升高，而静止不动精子数、精子畸形率和初级精母细胞染色体畸变率有所降低。

Strains, which were white or light brown when grew on the lead acetate media plates, were selected. Then, the different differential medium plates containing NaiS and as the only sulfur sources were used to select 24 strains, which grew well on plates, but didn't grow well on Na2SO3 plates.

Nanocrystalline Pb(Zr0.52Ti0.48)O3 was prepared from lead acetate, zirconium oxynitrate and tetrabutyltitanate by a sol-gel method.

以醋酸铅，硝酸氧锆，钛酸四丁酯为原料用溶胶－凝胶法制备了纳米Pb(Zr0.52Ti0.48)O3。

β-Cyclodextrin with the 6-hydroxyls protected by dimethyl-tert- butylsilyl was selectively oxidized by lead tetraacetate. After the silyl groups were removed off by boron fluoride-etherate, mono-2,3- dialdehydro-β-cyclodextrin as a cuniform molecule could be constructed.

用四醋酸铅将七元（6-O-二甲基叔丁基硅基）-β-环糊精选择氧化、并用三氟化硼乙醚脱硅基保护基后，再经分离、纯化，可获得具有&楔筒状&空腔的单-2， 3-二醛基-β-环糊精。

The photo decomposition reaction of lead styphnate is a simple thermal decomposition reaction, in which light energy rise will increase the rate of decomposition reaction of lead styphnate and the decomposition reaction has clear stages at higher light energy.

激光束能量增大能明显地提高斯蒂醋酸铅的分解反应速率，而且在较高的光能量下，分解反应出现明显的阶段性。

Changes of the NOS activity and the expression of NOS protein in central nervous systems of rats,which were subacutely intoxicated with oral exposure to lead acetate for 30 days,were observed with improved NADPH techniques and immunohistochemistry to study neurotoxic mechanism of lead.
