The results show that the sample is well dispersed particles with high purity and an average size of about 1 μm. Favorable substances of Ca2 and Sn appear during the cycling of zinc electrode containing CaSn6, Ca2 has continues to react with ZnO to produce calcium zincate, which can highly reduce the dissolvability of anode active materials and greatly improve the cycling performance of zinc electrode. The simulated Ni/Zn battery using CaSn6 and ZnO as the active material of zinc electrode has a high discharge plateau and an excellent cycling ability, and it can retain about 72.6% of initial discharge capacity after 50 charge-discharge cycles.

研究结果表明：通过共沉淀方法合成的CaSn6粒度分布均匀，平均粒径在1 μm左右，并且具有较高的纯度；添加CaSn6的锌负极在循环过程中游离出了Ca2和金属锡等有益物质，并进一步与ZnO反应生成锌酸钙，降低了锌负极活性物质在电解液中的溶解性，从而显著提高了锌电极的循环性能；以CaSn6与ZnO的混合物为负极活性物质的模拟锌镍电池具有较高的放电平台和优良的循环性能，经过50次循环后，电池放电容量保持为起始容量的72.6%。

Degree, the risk posed by each toxic substance. OSHA's discussions of individual sub-found at various levels of exposure, but made no estimate of the risk of experiencingthose health effects; instead, OSHA provided a conclusory statement that the new limitwould reduce the "significant" risk of material health effects, without any explanationof how the agency determined what was significant.

OSHA 关于特别物质的讨论包含了那种物质各种各样的研究和各种各样影响程度发现的健康效应的研究总结，但对经历那些健康效应的风险没有做估计；反而， OSHA 提供了一个结论性的声明：新限制会减少物质健康效应&重大&风险，确定什么是重大的部门没有做任何解释。

Methods Guinea pigs suffering from SOM were divided into three groups randomly, 6 for each group. Ectogenic surfactant, dexamethasone and 0.9% sodium chloride solution were injected into guiea pigs' tympanic cavities of group A, B and C respectively. The biochemical components and activity change of surfactant of Eustachian tube were analysed.

将分泌性中耳炎豚鼠动物模型随机分为A、B、C3组，每组各6只（12耳），分别用外源性表面活性物质、地塞米松和生理盐水注入豚鼠中耳腔内，然后观察豚鼠中耳变化；分析豚鼠咽鼓管内表面活性物质的生化成分和活性变化。
