In the standard test, it was found that the dustiness of nanopowder was much higher than submicro-powder. The average inhalable, thoracic and respirable dustiness mass fraction in mg/kg and the dustiness level of TiO2 nanopowder were 6713±546, 576±37 and 15±2, respectively, and were 142±20, 73±6 and 11±0.3 for ZnO submicro-powder.

在传统标准方法的测试结果发现奈米粉体的逸散性比次微米粉体高出很多，TiO2奈米粉体逸散时的可吸入性粉尘、胸腔区粉尘和可呼吸性粉尘质量分率分别为6713±546、576±37和15±2 mg/kg，扬尘等级分别为高等、中等以及低等。

The results showed that the aluminum plates had a much better effect than zinc plates in identifying crystalline free silica. The all open-faced samples had good uniformity in the filter no matter how many middles were used, but not so good for the closed-faced sampling. The calibration curve had a good correlation coefficient (r=0.995). Due to different industrial operating patterns, the distribution of crystalline free silica concentration varied by the industrial environment. The dust consisted of 10- 30% of crystalline free silica in all samples obtained from the foundry environments. The crystalline free silica was accounted for less than 10% in the respirable dusts.

结果显示，因为铝板对於结晶型游离二氧化矽具有较良好的补正系数，因此做为本研究的基底标准吸收校正的校正元素；SKC铝制旋风分离器搭配开匣式滤纸匣於一阶中环、二阶中环、三阶中环均有良好之均匀度，反之，搭配闭匣式滤纸匣其均匀度均不佳；分析检量线具有良好线性关系(r=0.995)，因作业型态不同，作业环境会有不同的浓度分布，综观作业环境中可呼吸性结晶型游离二氧化矽之含量均小於10%以下，总粉尘结晶型游离二氧化矽之含量约为10 – 30%之中。

In the respirable particulate matter in about 10% dependent on a variety of bacteria and other micro-organisms.

在可吸入颗粒物中10％左右依附着各种细菌等微生物。

The pollen and respirable should be used to change the main cause of asthma.

而花粉和可吸入变应原是引起哮喘的主要原因。

The results show that in the processes of shake 2out and finishing , molding , sand preparation , pouring , melting and coremaking , all the dusts are silica2 containing dust . The respirable dust （ 5 μm） occupies as high as 6915 %~ 78 %. Silica2containing dust in foundry air is not packed by Al. It indicates that silica dust in foundry air is fresh and highly pathogenic.

结果表明，清理、造型、配砂、制芯、熔化和落砂等工序游离SiO2 含量均超过10 %，分散度小于5μm的可吸入性粉尘偏高（6915 %~78 %），空气中矽尘没有Al 的包裹，是新鲜的粉尘，致病性强。

Methods AH dry powder inhalation was prepared by spray-drying method. Following spray-drying, resultant powders were characterized using scanning electron microscopy and laser diffraction, and the aerosolisation performance was determined using twin-stage liquid impinger. The process conditions were optimized with orthogonal design combined with multi-index test. The powder yield, aerodynamic diameter, angle of repose and respirable fraction were used as indices for orthogonal design.
