摘要用扫描电镜和透射电镜相结合的方法研究了镁在空气中燃烧所制得的MgO颗粒的粒度分布，结果表明，MgO颗粒的粒度分布是极不均匀的。不到1%的颗粒占质量的一半以上。这一结果解释了在MgO烟雾的红外光谱中观察到的异常。粒度分布可以与比表面积的吸附计测量结合使用，以给出表面粗糙度的量度。
Abstract It has been shown by a combination of scanning and transmission electron microscopy that the size distribution of MgO particles prepared by burning magnesium in air is extremely asymmetric. Less than 1% of the particles account for well over half the mass. This result explains an anomaly observed in the infra‐red spectroscopy of MgO smoke. The size distribution can be used in conjunction with sorptometer measurements of specific surface area to give a measure of surface roughness.
