一次粒径 meaning in English
primary particle size
Examples
- 2 several factors affect the crystalline size and the particle size of the powders
影响粉末一次粒径和颗粒粒径的因素很多。 - Hydrothermal modification temperature , hydrothermal modification time , concentration of aqueous cacl2 solution and solids holdup of mg ( oh ) 2 particles showed important effect on the morphology , crystalline structure and dispersion properties of the hydrothermal products
研究发现水热改性温度、水热改性时间、改性剂添加量和水热浆液固含均对水热产物的形貌和一次粒径有一定的影响。 - As the ratio of alcohol to water descends , both of them rise . as the solution concentration of nitrates descends , the crystalline size firstly descends and then rises . the nozzle pressure brings forth little affluence on the crystalline size of the powder , but the elevated pressure can enlarge the quantity and the size of the agglomeration
随酒精和水的比值的减小，粒径和颗粒粒径都增加；粒径随溶液浓度的减小，先减小后增加；一次粒径随压力的变化，变化很小，但随压力和流量的增加，团聚体增多、团聚粒径增大。 - Mgal2o4 nano - powders were prepared by the spray - pyrolysis method . an ethane - oxygen - assisted spray - pyrolysis equipment was designed and constructed , by which the spherical powders of crystalline with 10 - 60nm in diameter and agglomeration particle with 180nm in diameter were prepared . mgal2o4 nano - powders were characterized by x - ray diffraction , sem , laser granularity analysis equipment
本文用喷雾热解法合成了mgal _ 2o _ 4纳米粉末，设计并制作了乙炔和氧气助燃的喷雾热解装置，用此设备合成了一次粒径为10 ? 60纳米、团聚颗粒直径为180纳米的球形尖晶石粉末。 - The results show that all of them have little different effect on the crystalline size of ultrafine powder of a - ahc ^ , but they have greatly different effect on the secondary partical size . the azeotropic distillation is the most effective processing , it can prevent the formation of hard agglomerates and improve the sinter - ability of powder . the mechanism of drying stages preventing the formation of hard agglomerates has investigated
研究了三种不同的干燥方法(直接干燥法、酒精置换干燥法和共沸蒸馏干燥法)对粉体性能的影响。实验表明三种干燥方法对- al _ 2o _ 3粉体的一次粒径的差别性影响不显著，而对其二次粒径的差别性影响则很显著。
