There is the problem, can divide barrows, also can two times a two-headed needle,, twice a note in the time line, if your next time online, it is easy to see the line all together.

还有就是拉线的问题，可以分次拉，也可以两次一拉（配合双头针，真的可以做到天衣无缝的说），两次一拉需要注意的是拉的时候线要在上面，如果你在线在下面的时候拉，很容易因为看不见而把线都绞到一起了。

For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.

例如，尽管碱性元素并不进入锆石晶格，但它们可以影响Zr、Si、O离子的扩散速度，但是富钾和富钠的介质对锆石晶形发育的影响是有差别的，表现为：在富钾的介质中，将导致柱面的法向生长速度较锥面快得多，而锥面中，｛111｝的法向生长又较｛311｝快，由此决定了形成以｛311｝锥为主的双锥状晶体；在富钠的介质中，柱面和锥面都有一定程度的发育，但前者弱于后者，而柱面中，｛100｝的法向生长较｛110｝慢，由此决定了形成以｛100｝柱和｛111｝锥为主的短柱锥状晶体。

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.

本论文基于环糊精对被包结客体光谱性质的改变，开展了两大方面的研究：β-环糊精对姜黄属植物根茎主要成分—姜黄素、中药茜草有效成分—茜草双酯、抗麻风药物氨苯砜及抗炎药物萘丁美酮的主-客体识别反应机制研究：借助超分子包合物的紫外吸收光谱、荧光光谱或红外吸收光谱等手段，通过多种方法探讨并验证了超分子包合物的形成；研究了直链醇的加入对超分子体系的影响，揭示了三元体系中非共价相互作用导致超分子包合物表观结合常数降低的原因：对超分子包结反应进行了热动力学研究，探讨了各热动力学参数的变化趋势并从熵焓互补的角度考察了超分子包结过程；通过荧光猝灭实验进一步揭示了水相中β-环糊精增敏客体荧光的本质原因，从而为超分子化学提供新的理论和研究方法。
