模拟烹饪油烟的粒径分布与扩散

, 2017
烹饪油烟颗粒物粒径分布与扩散特性研究有助于解析其对室内空气质量和居民健康的影响,采用电子低压撞击器(ELPI)实时监测了油烟机开启和关闭状态下,模拟烹饪油烟发生处和3 m外位置处,0.03~10μm范围内油烟颗粒数浓度和质量浓度随粒径分布.油烟颗粒主要以655 nm以下的细颗粒为主.油烟机能够显著降低室内油烟浓度,开启油烟机后,油烟发生处颗粒数浓度从2.8×106个·cm-3降低到2.3×105个·cm-3,PM2.5(空气动力学直径≤2 ...

Characteristic of Soil Nutrient in Dam System and Its Relation with Erosion Environment in the Loess Hilly Region Ⅱ. Particles Distribution and Its Nutrient Condition in Dam System Soil

, 1997
坝系土壤粒径均以粉粒为主，含量占土壤的６６％～７０％。各土壤间粉粒含量差异很小，所不同的是，坝地富粘层粗粉粒少细粉粒多，砂粒少粘粒多，坝、坡轻壤层反之。土壤ＯＭ、ＴＮ主要集中在粘粒中，其浓度在粗细颗粒中差别悬殊。ＴＰ及ＴＫ在粗细颗粒中这种差别就较小。土壤中各形态锌均随着土壤颗粒变细而浓度增加，在＜０．００５ｍｍ粒径中浓度陡然提高。故坝地富粘层中ＯＭ、ＴＮ、ＡＺｎ的含量最丰。上述粒径及养分分布特点，揭示了在泥沙迁移淤积过程中 ...

リポソームの血中クリアランスに及ぼす粒子径の影響

Liposomes having various sizes in the diameter were prepared, and the effect of the sizes on the kinetics of blood clearance was investigated. As the result, it was proved that there was the size to minimize the blood clearance of liposomes. The size was

冻结对沙丘土壤抗风蚀能力的影响

Shuitu Baochi Xuebao
目的 明确冻结作用对沙丘土壤可蚀性及抗蚀性的影响，可加深黄河乌兰布和沙漠段冬季风沙入黄过程机理的认识，并为区域入黄沙量建模与估算提供重要科学依据。方法 通过流动沙丘迎风坡表层干沙、湿沙及冻结土层的沙粒粒径筛分试验和不同水分冻结前后的土壤进行抗剪强度测试，研究沙丘土壤冻结后抗风蚀能力。结果 沙丘不同坡位沙粒在水分的黏结作用下粒径增加，粒径峰值由0.15~0.2 mm向0.3~0.355 mm集中，约35.12%细砂颗粒黏结在一起形成较大的中砂颗粒。冻结后出现极细砂，粒径峰值为0.5~0.6 mm ...
