系统地计算了从轻到重的一系列元素极限温度的同位素分布，并从中抽取出热核的热稳定曲线。

We systematically calculated the isotope distributions of limiting temperatures for a series of nuclei from light to heavy nuclei, and obtain a thermal stability line for hot nuclei.

当抽取样本多于此值后， 曲线下降缓慢。3）落叶松人工林的样地抽样效果要好于柞树林的样地。

Their fluctuation degrees were also decreasing as the number of sampling points was increasing. 3) This technique used in Larix plantations was better than Mongolian oak forest.
