环境教育渗透中学化学教学现状调查及案例设计

通过对乌鲁木齐市三所中学高一年级学生环境意识情况的调查，获取了学生在有关化学的环境知识掌握、利用化学知识认识环境问题、提出解决环境问题的可能方法和途径、养成自觉的环境保护行为等方面的信息。根据信息，对调研学校学生环境知识掌握的情况、学生环境意识的水平等进行分析思考与讨论，找出症结所在；然后根据化学教学大纲的要求，结合学校教学进度，运用合适的教学方法，设计教案，进行授课，再对授课学校的学生进行二次调查；最后进行反恩，总结提出在中学化学中渗透环境教育的建议。

Localization and the interface between quantum mechanics, quantum field theory and quantum gravity II: The search of the interface between QFT and QG

The main topics of this second part of a two-part essay are some consequences of the phenomenon of vacuum polarization as the most important physical manifestation of modular localization. Besides philosophically unexpected consequences, it has led to a new constructive “outside-inwards approach” in which the pointlike fields and the compactly localized operator algebras which they generate only appear from intersecting much simpler algebras localized in noncompact wedge regions whose generators have extremely mild almost free field behavior.Another consequence of vacuum polarization presented in this essay is the localization entropy near a causal horizon which follows a logarithmically modified area law in which a dimensionless area (the area divided by the square of dR where dR is the thickness of a light-sheet) appears. There are arguments that this logarithmically modified area law corresponds to the volume law of the standard heat bath thermal behavior. We also explain the symmetry enhancing effect of holographic projections onto the causal horizon of a region and show that the resulting infinite dimensional symmetry groups contain the Bondi–Metzner–Sachs group. This essay is the second part of a partitioned longer paper.     

Unprincipled microgravity

I argue that the key principle of microgravity is what I have called elsewhere the Lorentzian strategy. This strategy may be seen as either a reverse-engineering approach or a descent with modification approach, but however one sees if the method works neither by attempting to propound a theory that is the quantum version of either an extant or generalized gravitation theory nor by attempting to propound a theory that is the final version of quantum mechanics and finding gravity within it. Instead the method works by beginning with what we are pretty sure is a good approximation to the low-energy limit of whatever the real microprocesses are that generate what we experience as gravitation. This method is powerful, fruitful, and not committed to principles for which we have, as yet, only scant evidence; the method begins with what we do know and teases out what we can know next. The principle is methodological, not ontological.

萘及其1-卤素取代化合物的荧光光谱的量子化学研究

萘及其化合物一般具有较大的共轭体系,是一类良好的电致发光材料.对萘及其卤代化合物的荧光光谱进行了理论研究.在B3LYP/6-31G水平下优化了4种化合物的几何构型.在振动分析中,均未出现虚频率.基于此,在B3LYP/6-31G的水平下计算了该类化合物的荧光光谱,所有计算结果与实验值基本吻合.

基于自适应相位旋转的Grover量子搜索算法

在使用Grover量子搜索算法对给定规模的无序数据库搜索时,随着搜索目标数的增加,获得正确结果的概率大幅度下降.分析了出现这种现象的原因,研究了算法中的Grover叠代过程,提出了一种新的自适应相位旋转策略.应用这一策略,当搜索目标数超过目标总数的(3-√5)/8时,只需两步搜索;当搜索目标数超过目标总数的1/4时,只需一步搜索,即可获得恒等于1的成功概率.实验表明新相位旋转策略是有效的.
