b粒子 meaning in English

beta particles

The results approve that i ac i is a good parameter to be a token of the diameter distributing of particles . then a criterion of mean fluctuation difference is put forward for b particle . fluctuation complexity varied with different particle , static bed height diameter particle and axis position of sensor are studied
本文认为是颗粒密度的差异造成涨落复杂性均值的差异，而平均涨落偏差| c |广定程度上是颗粒粒径分布的一个重要衡量指标，而且针对b粒子提出了平均涨落偏差判据，实验数据和该判据有很好地符合。
