Safflor Yellow, extracted from Safflor, with proved pharmacological effect that can expand coronary artery, lower blood pressure, resist thrombus, endure anoxemia and restrain immunity, will have a good developing and applying future. Since 1970s, more than 200 kinds of components such as flavone, lignocelluloses and alkine, have been extracted from Safflor.

红花黄色素(Safflor Yellow,SY)是从红花中提取的有效成分,具有扩冠、降压、抗血栓、耐缺氧、免疫抑制等多种药理学功效,有良好的开发和应用前景。70年代以来对红花的化学成分进行了广泛的研究,已分离出了二百多种化学成分,其中主要有黄酮类、木脂素类、多炔类等。

And experts paid more attentions to integer perception while listening to music.3. It also showed the position effect, that was irregular chords appeared at the third or fifth position, and the swings and the delitescence were quite different. It uncovered the different neural modes at different music perception phases.4. The two components had no significant differences with their swings at the three attention levels. It meant that these two ERP components could be acquired under non-attention condition, and music processing was automatic.

更多伏期更早,表明在时间维度和程度上,专家的整合程度要优于一般被试,专家更加注重对音乐的整体知觉。3通过违例和弦出现位置的不同,如违例和弦分别出现在第三位置和第五位置上的对比研究,发现第五位置上产生的ERAN和N5比第三位置上产生的振幅更大,表明这两种成分受违例位置的影响,揭示了音乐知觉不同阶段认知神经模型的差异。4这两种成分在三种注意水平下没有显著性差异,表明这两种ERP成分在非注意条件下就能够产生,人类的音乐加工是自动的。

His analysis of procreation is frequently criticized on the grounds that it presupposes an active, ensouling masculine element bringing life to an inert, passive, lumpen female element; it is on these grounds that Aristotle is considered by some feminist critics to have been a misogynist.

他有关生殖的分析经常受到批评,因为亚里士多德的预设了一个积极的、赋予灵魂的雄性成分,他为无生命的、被动的、残缺的雌性成分带来生命。某些女性主义批评家为此认为亚里士多德是厌恶女人的人。

Finally,we discuss the mixing and decays of multi-resonances via studying the properties of the pseudoscalar and scalar mesons.For the pseudoscalar mesons, we find the eta(1410) is mainly a glueball state by studying the decays of the ground pseudoscalar mesons. For the scalar mesons, we suggest the ground mesons contain neglect

对于赝标介子,通过研究它们的衰变发现eta(1410)的主要成分是胶球,对于标量介子,借助描述五个标量介子混合的质量矩阵,通过拟合观察到的标量介子的质量,发现基态标量介子中的胶球成分可以忽略,而其径向激发态中含有比较多的胶球成分。

In this paper we have found the main component s in a n -dimension random vector X , the so called main compon ents don′t contain linear relation and the others of X can be expressed as the linear combination of the main component s.

本文提供了在多维随机变量中寻找主成分的一种方法,证明了其余分量均可表示为主成分的线性组合,解决了多维随机变量的各个分量之间所存在的线性关系问题。

By the comparison of juice tlavour components with those of wild grape wine,wefound that wild grapes consisted of acetals,esters,alcohols, aldehydes, ketones etc,theyexisted in glycosidically-bound forms.Some wine flavour components had been poten-tially in grape,fermentation helped them showup,many alcohols and esters formedmade wine aroma and flavour richer and more complicated.

对葡萄汁与酒中的香味成分对比发现,野生葡萄中的香味成分由烷、酯、醇、醛、酮等组成,它们可能以结合态存在于汁中;葡萄酒中的许多香味成分已潜在于葡萄原料中,发酵能使它们充分表现,发酵中形成了较多的醇、酯类物质,使酒的风味更浓郁、复杂。

However, the taxa of strictly tropical distribution are still underrepresented in the flora of southeastern Yunnan compared to Indo-Malaysian flora, and the families of mainly subtropical to temperate distribution, such as Magnoliaceae, Theaceae, Cornaceae, Styracaceae, Symplocaceae, Aquifoliaceae and Caprifoliaceae, are well represented in the flora. Some characteristic families of temperate East Asia, such as Diapensiaceae, Dipentodontaceae, Eupteleaceae, Grossulariaceae and Toricelliaceae are also present in the flora of southeastern Yunnan.

由於位於东南亚热带北缘山地及其地质历史原因,云南东南部的热带植物区系中严格热带分布的成分不多,仍以边缘热带成分为主,并有相对丰富的亚热带-温带科如木兰科、山茶科、山茱萸科、山矾科、忍冬科、冬青科等以及一些东亚和喜马拉雅特徵科,如岩梅科、十齿花科、领春木科、茶藨子科和鞘柄木科,显示了它与东亚温带植物区系也有较多联系。
