Conditions for each simulated sample as assigned to a random number generator.

1 to 3 samples were generated according to conditions in each row. Sim.: Number of simulated samples generated in each group; N: sample size; k: number of components (morphotypes); RAn: Relative abundance of each component n; Tn: Mean thickness of each simulated component n; SD: standard deviation of the sample distribution.

依据每行指定的条件，生成1至3个样本。Sim.：每组生成的模拟样本（simulated samples）数量；N：样本量（sample size）；k：组分（形态型，morphotypes）的数量；RAn：第n个组分的相对丰度（relative abundance）；Tn：第n个模拟组分的平均厚度（mean thickness）；SD：样本分布的标准差（standard deviation）。
