1·The likelihood ratio criterion of sphericity test, its asymptotic expansion and limiting distribution are obtained.
论文得到了球形检验的似然比准则，它的渐近展开与极限分布。
2·The effects of slurry solid content and operation technology on the sphericity and average diameter of the microspheres were investigated.
论文其次研究了操作工艺、料浆固含量对微球粒径与球形度的影响。
3·With the drop of concentration, the sphericity goes bad, particle size decreases and particle distribution becomes narrow.
结果表明：随母液固含量的降低，样品的粒径变小，粒径分布也更为均匀，但其球形度变差；
4·The effectiveness of classical sphericity and Krumbein sphericity was compared to discribe chip-shaped fossil fuel, and the influence of sphericity on fiuidization characteristics was studied.
比较了不同球形度概念对片状化石燃料的描述效果，研究了片状化石燃料球形度变 化对其流态化特征的影响。
5·The bodies of some other cells showed sphericity with short processes.
另有一些胞体呈球形，突起较短。
