In the present study, influences of 6-BA (6-benzyl aminopurine) on cluster root formation, exudation of citrate and malate and their concentration in the root clusters of P-deficient white lupin plants were studied by using of non-destructive localized collection method and high-performance liquid chromatography analyze technique.

本文研究了6-BA（6-苄基腺嘌呤）处理对缺磷的白羽扇豆排根形成的影响，并利用非破坏性原位收集方法和高效液相色谱技术研究了6-BA处理对根簇分泌柠檬酸和苹果酸及组织中这两种有机酸含量的影响。

On the first day after exposure these changes gradually expanded to amygdaline nucleus cluster and piriform cortex.

暴露后1d，上述变化逐渐扩展至杏仁核簇和梨状皮层。

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

经过二簇检验、分枝长度检验和相对速率检验，删除2条速率不恒定的序列后，用剩余的13条序列，以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。

Inflorescences lateral or terminal on old or new growth; male and female inflorescences separate: male spikes in clusters of 3, lateral at base of new growth or rarely on old growth, pendulous; female spike terminal on new growth, erect. Flowers anemophilous.

在老的或幼枝上的花序侧生或顶生；雄和雌的花序分开：在3的簇生里的雄性穗状花序，在老枝上的幼枝或很少的侧的在基部，下垂；在幼枝，直立上顶生的雌性穗状花序。

His possibly anergic effect may result from discrete structural alterations of the T-cell-epitopes caused by the formalinization process.

这种可能的变应性效应，可能是由于甲醛处理过程引起的 T 细胞抗原决定簇的结构发生改变。

The results revealed that iontophoresis could significantly improve the penetration of SLN. The fluorescence of images indicated that the accumulation and the depth of QDs-SLN reached in skin increased with times. Anodal delivery of QDs-SLN resulted in a higher accumulation of QDs-SLN in skin than those of cathodal delivery. Furthermore, the vertical images of skin showed that fluorescence assemble in follicle and dermis, indicating that follicle and the junctions between the corneocyte clusters provide the pathway for SLN penetration into skin.

QDs-SLN在皮肤中的滞留量及透皮深度随离子导入时间的增加而增大；正极导入时，QDs-SLN在皮肤深层组织中的含量较高；通过荧光显微镜对垂直于皮肤表面的纵切猪耳全皮中QDs-SLN的分布情况进行考察，结果提示皮肤附属器及角质层中蛋白簇间的结合部位可能为SLN的透皮路径。

The synthesis, types of antioxidant s and their antioxygenation mechanism were reviewed.

抗氧化剂被广泛应用于制药、功能化妆品等的生产、加工和贮藏过程中，其通过抑制生物机体活性氧簇的产生，或阻止其进一步链式氧化反应达到抗氧化目的。

Stamens many to rarely few (9), in [3 or]4 or 5 bundles that are free and antipetalous or variously connate, with filaments variously united or apparently free and then sometimes sterile; anther dehiscence longitudinal.

The morphology and microstructure characteristics of the apertured silver doped TiO2 microtubes were characterized by means of the X-ray powder diffraction, thermal analysis, transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy and N2 absorption.

氮吸附的结果显示该样品具有很高的比表面积，银的修饰没有显著影响二氧化钛微管的孔结构； XRD的表征结果显示，银修饰的二氧化钛多孔微管具有良好的锐钛矿晶型； XPS的分析结果表明银以游离的金属态存在； TEM的观测结果显示，银团簇沉积于二氧化钛纳米晶粒的表面。

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。
