首先应用更新方程理论研究最终破产时赤字的分布，然后应用随机模拟的知识研究有限时间内破产赤字的经验分布，并在假设索赔是指数分布时，考察了2个具体的、在不同时间和不同初始盈余下破产赤字的经验分布，得到一个值得注意的结论，有助于加深对有限时间破产赤字分布的了解。

By testing χ2 and F distribution of data, it was proved that the method had a better approach to theoretical distribution curve than above two methods.

Having such properties, in a finite range of ［0,1］, as monotonic decreasing, unimodal distribution, and monotonic increasing, the β-distribution function with 2 or 3 parameters was used in describing the distribution model of coal particles different in density in a jig bed.

根据β分布在有限的［0，1］区间内具有单调下降、单峰分布和单调上升等各种形态，用2参数或3参数的β分布作为描述各密度颗粒在跳汰床层中分布的数学模型。

Five pairs of 45S rDNA loci and two pairs of 5S rDNA signals were detected on chromosomes of Cucurbita moschata Duch. Luffa cylindrical Roem. contained five pairs of 45S rDNA loci and one pair of 5S rDNA loci. In Benincasa hispida Cogn., two pairs of 45S rDNA sites and one pair of 5S rDNA site were detected. In this species, 5S rDNA and one pair of the 45S loci were collocated closely in chromosome 7S. 45S rDNA chromosomal distribution patterns were highly conserved among the three species, althoufh their number varied markedly. The 5S rDNA sites on chromosomes among the three species were highly polymorphic.

南瓜有5对45S rDNA位点， 2对5S rDNA位点；丝瓜具有5对45S rDNA位点， 1对5S rDNA位点；冬瓜具有2对45S rDNA位点， 1对5S rDNA位点， 5S rDNA位点与其中一对45S rDNA位点都位于7号染色体短臂上，并在物理位置上紧密相邻。45S rDNA在这3种作物染色体上数目变化较大，但在染色体上都倾向分布在短臂末端，其分布模式较为一致。5S rDNA在这3种作物染色体上数目相对保守，但在染色体上分布的位置变化较大。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
