Along the research line opened by David Bohm, this article reveals that thought is the adjustment of mind by nature and society, whose operations take the logical form opposite of metaphysics, and the underlying free mind aims at to seek satisfaction according to the principle of pleasure, whoseoperations take metaphysical, imaginational and non-logical form.

洪定国 本文遵循戴维·玻姆所开拓的研究路线，揭示思想是心灵被自然与社会的调制，采取形下的逻辑运作形式；深层的自由心灵按愉悦原则以追求满足与和谐为目的，采取形上的、想象的非逻辑运作形式。

It is found thatthe fractal dimension D=1.25 corresponds to the lowest criticalcoupling constant αc=1.9,D=1.73 corresponds to the highest criticalratio of dielectric constants ηc=0.163,and when D≤1.145 bipolaronscan not exist at any rate.In chap,4,we will propose a novelapproach to the calculation of the exciton ground-state energy for thestrong-coupling case.Different from all previous methods,the wavefunction of the phonon part is assumed to take a form related to thewave function of the relative motion.We obtain the exciton energy bysolving the derived integrodifferential equation rather than select ahydrogen-like form to minimize the energy expectation.

结果发现，分数维的维数D＝1.25对应最小的临界的电-声耦合常数(αo＝1.9)，D＝1.73对应最大的临界的介电常数比(ηc＝0.163)，当分数维的维数D≤1.145时，双极化子无论如何也不可能存在，在第四章中，我们将提出一种新颖的变分方法来计算强耦合的激子-声子系统的基态能，不同于以前所有的方法，我们取声子的波函数与相对运动波函数有关的形式，而不是假定一个固定的关于相对运动坐标r的函数形式，得到相对运动波函数所满足的非线性的微分积分方程，我们数值求解这个微分积分方程得到系统基态能，而不是选择一个类氢原子的波函数变分使得能量的期待值最小。

Chemically, fluoroquinlones are an amphoterics molecule processing major ionizable groups, a basic piperazine amine and acidic carboxyl. The form of drugs was greatly affected by the acidity in aqueous solution. Thus the effect of pH values in aqueous solution on the fluorescent properties of fluoroquinolones was studied in details, the spectral properties of each form was characterized. It was found that the fluoroquinolones exhibit weak fluorescence in strong basic solution.

氟喹诺酮类药物分子结构中既有羧基，又有哌嗪氨基，它们所处环境的pH值对其存在型体有很大影响，因此我们详细研究了水溶液的pH值对该类药物光谱特性的影响，并对于各型体光谱特征进行归属，发现强碱性溶液中其发光较弱。

Class of Ⅱ of the smooth ~ that sweep Ⅰ shows low density or wait for low jumbly density, the position relatively class of the Ⅰ after expressing shallow; to increase does not have aggrandizement more, oedema is much light or submit form of section of intermittent or successive loop without;Ⅱ class aggrandizement or piece conglomerate form aggrandizement, oedema degree is differ, enhance time - class of Ⅱ of ~ of density curve Ⅰ and normal head pledge in vain similar.

平扫Ⅰ~Ⅱ级呈低密度或等低混杂密度，位置较表浅；增强后Ⅰ级多无强化，水肿多轻或无；Ⅱ级呈断续或连续环结节形强化或片团状强化，水肿程度不一，增强时间-密度曲线Ⅰ~Ⅱ级和正常脑白质相似。

The first synthetic route uses 1,2,4-trimethoxybenzene and chloroacetonitrile in forming 2,4,5-trimethoxy-a-chlor-acetophenone under the anhydrous condition, then the intermediate condensates with papaverine forming the core pyrro[2,l-a]isoquinoline, followed by formation and lactonization to form the lactone ring. The second synthetic route uses prepared aldehyde with prepared ethyl nitroacetate by Knoevenagel condensation to obtain 2-Nitro-3-(2,4,5-tris-methoxy-phenyl)-acrylic acid ethyl ester and 2-Nitro-3-(2,4,5-tris-benzyloxy -phenyl)-acrylic acid ethyl ester etal intermediates. The lamellarin skeleton could arise from condensation of the papaverine and these intermediates by Michael reaction, the ester group is provided for subsequent lactonization. The third synthetic route uses coumarin or indan-l,3-dione derivatives and papaverine to form lamellarin under basic conditions.
