结论］该研究为进一步开发云南省的好生植物资源，寻找野生八角更多具有生物活性的化学成分提供了依据。

Data obtained by thin-sections analysis, cathodoluminescence emission analysis and SEM/EDX show that carbonate cements seem to be the uppermost cements composed of ferroan sparry calcite and ankerite and are distributed mostly in the depth interval of 100 m below the unconformity, with their contents increasing with the depth.

通过薄片观察、阴极发光、扫描电镜/能谱分析，认为碳酸盐胶结物是研究区砂岩最主要的胶结物成分，其主要类型为方解石和铁白云石，垂向上含量随深度增加而增加，多集中分布在白垩系和侏罗系之间的不整合面之下约100 m的范围之内。

Betel quid and areca nut are both recognized as carcinogens, however, the effects of their ingredients on cells are not poorly studied.

摘要 槟榔嚼块(betel quid， BQ)与槟榔子(areca nut， AN)已经被公认为致癌物，然而有关槟榔成分对细胞的影响之研究却不多。

In addition, the gamma ray bursts, which are mysteriousphenomena in high energy astronomic physics research, are also studied in thethesis.

联合实验的主要目的是使乳胶室和大气簇射阵列的特点相互补充，提供更多的信息，进行宇宙线原初粒子的成分、能谱以及超高能强相互作用的研究。

In the present day, PCA is applied widely in many research fields of astrophysics.

目前，主成分分析法被广泛应用于天体物理的诸多研究领域中。

Formulae for the structural volume fraction of phases and the quantitative relationship between the phase amount s obtained respectively by calculations in atomic fraction and in mass fraction of elements are derived for multi-phase alloys.

导出了多相合金组成相结构体积分数以及用成分的原子分数与质量分数求得的相含量之间的关系。

Furthermore, the metallic glass samples are prepared by vacuum injection method and the rationality of above-mentioned relationships and RBF models is directly verified. It is shown that there are extremum phenomena between the Rc andΔd ,Δe and v respectively. However, the positions of the extremum are different from different alloy systems and the extremum phenomena may be related to the optimum composition region and the optimum additive quantity. More elements in the alloy are in favor of the improvement of the GFA. And as for the high GFA alloy, the atomic percentage, atomic radius difference and atomic electronegativity difference are harmoniously matched.

d、Δe和v与临界冷却速度Rc的关系中都出现极值现象，对于不同的合金体系，极值出现的位置不同；金属玻璃的最优成分范围以及各种添加元素的最佳添加量行为，可能与此极值现象相关；合金中包含的组元数目多有利于提高其玻璃形成能力，玻璃形成能力强的合金，其各个组元的原子百分含量、组元原子半径差及其电负性差之间的搭配是很和谐的；融合建模的合金系之间包含的主要组元数量和种类越相近，所建立的模型的可靠程度越高，其预测结果与实测结果越吻合。

Objective consideration of contemporary phenomena compels the conclusion that success or failure in competitive activities exhibits no tendency to be commensurate with innate capacity, but that a considerable element of the unpredictable must inevitably be taken into account.

对现实中诸多现象的客观观察使得我们不得不得出这样一个结论：竞争活动中的胜负并没有呈现出与人们内在能力的一致性。因此，我们不得不对相当大成分的不确定因素加以考虑。

Summarizing the results from this analysis, it was revealed that the analytic contained abundant components of neolignans , having dimeric phenyl propanoid structure with unsymmetrically condensed benzofuran skeleton attached with different sugar moieties.

结果显示此部分为富含木质素类化合物，所分析出的化合物多为首次在该植物发现，其中有massonianoside D(1)、7、8和C-veratroylglycol (9)为已知化合物，而2~6、10~14是新颖天然物成分。

It is characterized by ineffective erythropoiesis and by the presence of bi- and multinucleated erythroblasts in bone marrow, with nuclei of equal size and DNA content, suggesting a cytokinesis disturbance.

它的特征是无效红细胞生成以及骨髓中存在的双核和多核幼红细胞，这些细胞含有等量的细胞核和DNA成分，提示胞浆紊乱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
