| 1. | Standard test method for particle size range of peat materials for horticultural purposes
园艺用泥炭材料粒度范围的标准测试方法 |
| 2. | It is in white or light gray color and has a particle size ranged from 20 to 500 microns
颜色为白色或浅灰色，粒度在20 - 500微米之间。 |
| 3. | Determination for particle size range , effective size and uniformity coefficient of ion exchange resins
离子交换树脂粒度有效粒径和均一系数的测定 |
| 4. | Contrarily , w - cu powder prepared by reducing the mechanically mixed wo3 - cuo oxides has a particle size ranging from 0 . 1 to 1 m with irregular partic le shape and non - uniform distribution of w and cu composition
而机械混合氧化物共还原法制备的w - cu复合粉颗粒较粗大，其粒径分布范围在0 . 1 1 m之间，颗粒形状也并不规则。 |
| 5. | The test results have showed that the w - cu powder produced by the homogeneous precipitation process has a near spherical shape , a particle size ranging from 50 to 200nm and a uniform distribution of w and cu gradients
研究结果表明，均相沉淀法制备的w - 30wt . cu复合粉末颗粒明显呈球状， w 、 cu组分呈均匀、弥散分布，透射电镜观测显示其粒径范围在50 - 200nm之间，为超细粉体。 |
| 6. | For the titania films with hpc as additive , we had the following opinions : titania films with the particle size ranging from 20nm to 120nm could be obtained with hpc as dispersant ; a little amount of hpc promoted the formation of a loose structure of the films and the decrease of particle size ; the particle size hit the lowest point when the amount of hpc was 3m ; the structure of titania films became denser and the particle size increased with further adding of hpc in the solution
对以hpc为添加物的tio _ 2薄膜样品的研究表明： hpc的加入形成了粒径为20 - 120nm的tio _ 2薄膜。少量hpc的加入使tio _ 2薄膜的微观结构变的疏松，粒径降低。当hpc含量为3m时，粒径最小。 |
| 7. | The result indicates that for enhancing particle target collection efficiencies , the inertia effect of particle and the coulombic force between particles should be carefully distinguished in different particle size ranges ; and proves that when droplets are weakly charged , it is still effective for the collection of sub - micron charged particles
结果表明，在不同粒径区间内，粒子的惯性效应和雾滴与粒子间的库仑力对强化粒子靶效率的作用需要仔细加以辨认，同时证明?当雾滴弱荷电时，对亚微米带电粒子捕集依然是有效的。 |
