摘要：从一个球粒陨石到下一个球粒陨石的尺寸变化被认为是由于早期太阳星云中的一些分选过程。分选过程的假设包括球粒分选质量和分选的一些空气动力学机制，这样的空气动力学机制是湍流浓度（TC）的过程。我们提出了一系列的球粒数据从几个不同的陨石的统计检验的结果。数据没有明确区分分选参数的各种选项，但我们发现数据与球粒半径的对数正态分布或（三参数）威布尔分布不一致。我们还发现，除了一个测试的球粒数据集是一致的，从TC分布。
Abstract– The variation in sizes of chondrules from one chondrite to the next is thought to be due to some sorting process in the early solar nebula. Hypotheses for the sorting process include chondrule sorting by mass and sorting by some aerodynamic mechanism; one such aerodynamic mechanism is the process of turbulent concentration (TC). We present the results of a series of statistical tests of chondrule data from several different chondrites. The data do not clearly distinguish between various options for the sorting parameter, but we find that the data are inconsistent with being drawn from lognormal or (three‐parameter) Weibull distributions in chondrule radius. We also find that all but one of the chondrule data sets tested are consistent with being drawn from the TC distribution.
