The program structure designing and optimizing tests of GRAPES physics

According to the modularization and standardization of program structure in Global/Regional Assimilation and Prediction System （GRAPES）, the plug-compatible and transplantable regional meso-scale and global middle-range physics software package is established. The package＇s component integrality is comparative with the other advanced models physics. A three-level structure of connecting GRAPES physics and dynamic frame has been constructed. The friendly interface is designed for users to plug in their own physics packages. Phenomenon of grid-point storm rainfall in numerical prediction is analyzed with the numerical tests. The scheme of air vertical velocity calculation is improved. Opti- mizing tests of physics schemes are performed with the correlative parameters adjusting. The results show that the false grid-point storm rainfall is removed by precipitation scheme improving. Then the score of precipitation forecast is enhanced.

Trans-Planckian philosophy of cosmology

I provide some philosophical groundwork for the recently proposed ‘trans-Planckian censorship’ conjecture in theoretical physics. In particular, I argue that structure formation in early universe cosmology is, at least as we typically understand it, autonomous with regards to quantum gravity, the high energy physics that governs the Planck regime in our universe. Trans-Planckian censorship is then seen as a means of rendering this autonomy an empirical constraint within ongoing quantum gravity research.     

Drawing scales apart: The origins of Wilson's conception of effective field theories

This article traces the origins of Kenneth Wilson's conception of effective field theories (EFTs) in the 1960s. I argue that what really made the difference in Wilson's path to his first prototype of EFT are his long-standing pragmatic aspirations and methodological commitments. Wilson's primary interest was to work on mathematically interesting physical problems and he thought that progress could be made by treating them as if they could be analyzed in principle by a sufficiently powerful computer. The first point explains why he had no qualms about twisting the structure of field theories; the second why he divided the state-space of a toy model field theory into continuous slices by following a standard divide-and-conquer algorithmic strategy instead of working directly with a fully discretized and finite theory. I also show how Wilson's prototype bears the mark of these aspirations and commitments and clear up a few striking ironies along the way.

现代物理学若干问题的哲学启示

通过考察粒子物理学关于物质结构和基本相互作用规律研究的 ３ 个基本问题：物质结构的层次、物质层次的特有规律和各种相互作用之间的联系，探讨了其在哲学上的一些启示：（１）物质具有可分性，但是无限可分的观点无法证实；（２）自然界各种相互作用既具有特殊性又具有相互联系，在高能标下可能存在一个统一的支配规律。     

小角度掠射X-Ray Diffraction用于离子注入后金属材料的物相鉴定

用小角度掠射 Ｘ 光法对工业纯铝，４５＃ 钢等材料表面经离子注入改性后的表层物质进行了物相分析，这一方法可以准确确定材料表层厚度为几十 ｎｍ 时的物相结构 ，从而为确立材料表层改性的机制提供了较为可靠的依据． 对比实验表明，采用小角度掠射 Ｘ 光衍射法比常规衍射仪法更加突出了表层物质对衍射谱的贡献，这为表面物理的研究提供了一种有效的方法．
