The correlation of properties between pure compounds and complex mixtures of heavy oils could be built by the proposed method.

验证结果表明，除个别结构基团的摩尔质量误差较大外，构建分子系综中沸点、统计结构基团的摩尔质量、相对分子质量、环和侧链分布均与实测值相近，与重油组成具有等效性。

The XRD results revealed that α-form,γ-form, or triclinic crystallization could be found in waterborne polyurethane matrix at different inorganic contents.

利用DSC及XRD图谱可知无机物的添加对於硬链段的结晶有较大的影响，结晶型态包括α-form、γ-form及三斜晶系。

In this study, we discussed the phylogenetic relationships in the Anura groups with the sequences of the 12 proteins encoded in the H-strand and 22 tRNAs of mtDNA from 21 species from GenBank. They all indicated that Anura were divided into the Archaeobatrachia and the Neobatrachia,these results supported the monophyletic origin of Anura.

结合饰纹姬蛙和金线蛙的mtDNA以及GenBank上公布的共21种无尾目的线粒体基因组，本文基于编码重链12个蛋白质的基因和编码22个tRNA的基因分别构建了MP系统树，分析了21种无尾目动物的亲缘关系，结果都显示将无尾目分为两大群，支持无尾目的单系起源。

Based on this information, offspring from 10 crosses where parents were known were genotyped by the 6 microsatellite loci and used for parentage analysis. The result showed that assignment success of the progeny to their 'true' mother and father was 88% and 78% respectively, which were lower than predicted by the Cervus simulations. This could be explained by the existence of null or mutant alleles and by Taq DNA Polymerase slippage in the microsatellite loci.

在家系混养的模拟实验中使用这6个高多态性的微卫星基因座从20个候选雌虾中找到真正母亲的概率为88%，从30个候选雄虾中找到真正父亲的概率为78%，低于理论预测值，分析可能与微卫星基因座中的无效等位基因，等位基因的突变以及PCR过程中 Taq 酶发生链滑移等因素有关。
