Measurements of mean residence time and penetration of submicrometer aerosols in flows in tubes were made within the range of Reynolds numbers from 0.07 to 0.26 by widening of aerosols pulses analysis of monodisperse polystyrene spheres solid particles injected in clean nitrogen flow through a diffusion battery of capillary tubes.

在Reynolds数0.07～0.26范围内，采用亚微米聚苯乙烯球形硬气溶胶粒子脉冲，测定了气溶胶粒子在毛细管扩散池组中的谱带展宽，由此获得了气溶胶在毛细管中的平均保留时间和穿透率。

The Schroeder D-AB-2 and D-AB-4 desiccant filter breathers feature a dual filtration process, removing water as well as solid contaminants (2 and 4 micron absolute), respectively.

该施罗德的D -AB- 2和D -AB- 4干燥剂过滤器呼吸功能的双重过滤过程，去除水以及固体污染物（ 2和4微米的绝对），个别的。

Whatever the Zn/H_2O_2 ratio is, there is only chestnut bur-like structure appeared after thermal oxidation at 850℃for 8h. DSC-TG results showed that while the content of the ZnO film shell on the zinc nanoparticle surface is about 50.4%, the melting and oxidation processes happened almost at the same time during the thermal oxidation process and the bushiest ZnO nanoneedles can be formed.

DSC-TG分析结果表明，纳米锌粉表面保护膜质量占到颗粒质量的50.4%时，热处理阶段氧化过程和熔化过程几乎同时发生，生长的ZnO针状产物最为茂密；对于微米锌粉，H_2O_2预氧化处理对其热行为及其最后形貌生长都影响不大，热氧化阶段是其控制阶段。

SEM and XRD results showed that the bushiest ZnO nanoneedles can be obtained after using H_2O_2 pre-oxidization at the Zn/H_2O_2 ratio of 20mg/ml and themal oxidation at 650℃for 2h and ZnO nanoparticles at the Zn/H_2O_2 ratio of 2mg/ml, and the morphologies were evolved from nanoneedles to nanoparticles between the two Zn/H_2O_2 ratios.

SEM和XRD分析表明，当在预氧化阶段Zn/H_2O_2为20mg/ml时，650℃热氧化2h后纳米锌粉氧化成茂密针状ZnO，当Zn/H_2O_2为2mg/ml时，生成颗粒状ZnO，处于中间浓度时，针状结构依次减少；预氧化微米锌粉无论Zn/H_2O_2比例为多少，850℃热氧化8h后的产物都为栗状ZnO。

Taiwan Gaoyin Company has opened up a new prospect in the global market monopolized by the United States and Japan and successfully developed nanometer diaphragm with extraordinary performances in electric capacity, discharge rate, micro-short cir cuit and cycle life, the thickness of which is only 10 micron.
