The wave function of the phonon is assumed to take thecoherent state,a self-consistent integrodifferential equationsatisfied by the electron wave function is derived.Solving for thisequation,we get the polaron ground-state energy E=-0.1085α2, whichis very close to these of previous strong-coupling theories.In chap.4,we will apply approaches developed in chaps.2 and 3 to discuss theimportant two-dimensional(2D)polaron problem.
把声子部分取成相干态的形式,我们推导出电子波函数所满足的非线性的微分积分方程,求解这个方程,我们得到基态能为E=-0.1085α2,它与以前的各种强耦合理论的结果非常接近,在第四章中,我们利用在第二,三章中发展的方法讨论很重要的二维极化子问题。

In this thesis, we describe a facile and economical synthesis of-abscisic acid from keto-isophorone and 3-butyn-2-ol through ketalization, oxidization, Witting-Horner reaction, reduction with chromium sulfate and other steps in 13% total yields. Compared to the previous routes, the starting materials are more commercially available and cheaper and the synthetic process is more easily controlled in our method, but the yield of this route is still to be improved.As to isostere principle, cyclopropyl and methyl vinyl are a couple of isostere.
本论文设计并完成了一条全新的外消旋脱落酸(1)全合成路线,从廉价的工业原料氧化异佛尔酮和丁炔醇出发,经过缩酮化反应、氧化反应、Wittig-Horner反应、CrSO_4选择性还原反应以及水解等七步反应实现了脱落酸的全合成,总产率达13%,与以往路线相比,该路线所用试剂廉价、合成路线简单,但产率有待提高。

Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.
本研究组前期工作发现,过量表达HmgD引起果蝇幼虫体内血细胞增生,并出现黑色素瘤,为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制,本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA,首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE,Spn27A在突变体中的转录发生变化,结果发现,Spn27A在三龄中期的表达量低于野生型,而PPAE的表达高于野生型,表明过量表达HmgD影响了酚氧化酶级联反应途径,低水平的Spn27A不足以抑制PPAE的活性,活化的PPAE催化了PPO的活性,使其转变成有活性的PO,从而促进黑色素的生成,使果蝇体内产生黑色素瘤。

Methods: Thirty ASA I nulliparous women were administered 10 ml bolus of epidural ropivacaine in the first stage of labor.
