SEM实验表明，镀层表面形貌为团粒状，颗粒大小较不均匀。
SEM experiment displays that the deposit has a (surface) morphology of granular structure with uneven grain sizes.
这种球形颗粒形状在加工过程中也起到积极作用，其功能体现水蒸气在球形颗粒和干气之间具有不均匀压力。
Spherical pellet shape also makes a positive contribution during the drying process which functions due to the differential partial pressure of the water vapor between the pellets and the drying gas.
结果表明：名义尺寸相同而实际尺寸相差较大的磨球所磨出的粉体粒度大且分布不均匀，烧结体硬质相颗粒粗大且等轴性差，抗弯强度和硬度均较低。
It is found that the grain size of the powders milled by balls with different diameters is big, the hard phase is big too and not uniform, the hardness and bending strength are also lower.
