走出科学教育的现代迷茫

科学与人文之争已历经上百年，在以知识为主导的新时代，科学教育倍爱世人的青睐。科学教育既是科学人才的产床，也是人性异化等扼杀人类文明、威胁人类生存的制造之所。科学教育必须走上与人文教育相结合的道路才能走出现代迷惘，并最终使科学真正带给人类以福祉而不是灾难。     

New polaron effect in magnetooptic phenomena in a quantum well

It is predicted that resonance coupling between two discrete electron energy levels corresponding to different size-quantization quantum numbers and different Landau quantum numbers can occur in a quantum well in a quantizing magnetic field. The resonance coupling is due to the interaction of an electron with LO phonons and results in the formation of polaron states of a new type. It is shown that for a certain value of the magnetic field, which depends on the splitting of the electron size-quantization levels, the absorption peak and the two-phonon resonance Raman scattering peak split into two components, the separation between which is determined by the electron-phonon coupling constant. The resonance coupling between size-quantization levels with the same Landau quantum numbers is also studied. The splitting of the peaks in this case is virtually independent of the magnetic field and can be observed in much weaker fields. The experimental observation of the effect will make it possible to determine the relative position of the electronic levels and the electron-phonon coupling constant. Pis’ma Zh. éksp. Teor.

Preparing polymer brushes on polytetrafluoroethylene films by free radical polymerization

Films of polytetrafluoroethylene (PTFE) were exposed to sodium naphthalenide (Na/naphtha) etchant so as to defluorinate the surface for obtaining hydroxyl functionality. Surface-initiators were immobilized on the PTFE films by esterification of 4,4′-azobis(4-cyanopentanoic acid) (ACP) and the hydroxyl groups covalently linked to the surface. Grafting of polymer brushes on the PTFE films was carried out by the surface-initiated free radical polymerization. Homopolymers brushes of methyl methacrylate (MMA) were prepared by free radical polymerization from the azo-functionalized PTFE surface. The chemical composition and topography of the graft-functionalized PTFE surfaces were characterized by X-ray photoelectron spectroscopy (XPS), attenuated total reflectance (ATR) FT-IR spectroscopy and atomic force microscopy (AFM). Water contact angles on PTFE films were reduced by surface grafting of MMA.

试述泰山碧霞元君演进的三个阶段

按照历史与逻辑相统一的方法，可将泰山碧霞元君的演化进程划分为三个阶段。最初，由曹操的名篇《气出唱》创造出泰山云霞仙境中的天仙玉女这一审芙意象，曹植、李白等诗人又不断加以描写、渲染，从而使泰山玉女在中固古代社会享有很高的知名度。然后，宋真宗为这位神女易玉像、砻石龛。引导泰山玉女从诗人的作品中走出，走进了香火缭绕的宫祠。最后。明宪宗修宫祠、赐颠名，其影响所度，使得明清时期的碧霞元君在京城及全国各地建庙，香火大盛，碧霞元君一名也沿用至今。与此同时，道士们一方面凭着斋醮科仪、住持焚修和承办庙套、营造节庆的狂欢气氛，对泰山玉女进行了卓有成效的炒作；另一方面凭着一片赤诚，兢兢业业，惨淡经营。博得了几代朝廷及地方官员对各种奉祭碧霞元君活动的赞赏和支持，这就使泰山碧霞元君成为中国道教的一大主神。     

诚信教育:高校德育的一项重要内容

随着我国社会主义市场经济的不断完善、发展，诚信教育呼之欲出。新的社会环境下．诚信的内涵及其呈现出的新特点，要求教育应把诚信教育作为高校德育的重要内容并纳入其全过程，应有针对性、行之有效地开展诚信教育。     

静压下半导体微腔内激子与光子行为的研究

由于腔模与激子对压力的依赖关系不同,所以可以选择不同的压力使激子和光场处于不同的耦合状态,从而实现对耦合的调谐。利用这种办法,我们观测到了代表激子与光场强耦合作用的Rabi分裂。由于在我们现有样品结构中压力对激子本征行为的影响很小,与以前报道的温度、电场等调谐方式相比,这种调谐方法不仅可以有效地调谐半导体微腔内激子与腔模的耦合程度,而且能够保持激子的本征性质在整个调谐过程中基本不变。这有助于研究在强耦合过程中激子极化激元的本征性质。将实验结果与压力下激子与腔模耦合理论进行拟合,得出了正确的Rabi分裂值。     

Rough隶属函数关于集合并与交的一种高精度计算方法

近些年来，许多处理近似问题的方法陆续被提出，其中利用Rough集理论计算两个集合的并和交的Rough隶属函数方法是被用较多的一种方法，但毕竟该方法精度较差。为此，介绍了一种精度较高的计算两个集合的并和交的Rough隶属函数方法，它克服了前者利用Rough集理论计算Rough隶属函数的复杂性，而迎来了简单和高精度的特点。     

The opacity coefficient method—nongray determination of inhomogeneous atmospheric extinction

The computation of radiation transmittance in nongray, inhomogeneous atmospheric models is frequently complicated by complex bands of line spectra which range in value over many orders of magnitudes and depend strongly on either or both of pressure and temperature. We present here a new opacity sampling technique which is shown to determine correctly the wavelength-averaged extinction due to path-dependent realizations of banded line spectra. The technique is easy to implement computationally and is applicable to a wide variety of atmospheric problems in which frequent iteration of the radiative transfer model is required. We consider two such instances: modeling of solar flux attenuation for use in a time-dependent planetary ionosphere model and retrieval from nadir measurements of backscattered solar irradiance. The power of the new method lies in its straightforward analytical treatment of both atmospheric inhomogeneity and spectral complexity. It is thus relevant for both retrieval and radiative transfer modeling purposes.
