基于信息流的思想库政策影响力分析框架研究

以知识运用理论为基础,使用信息流抽象的方法分析思想库参与政策形成的过程,设计出一个综合性的思想库政策影响力分析框架。该框架分为两个部分,一是思想库影响政策决策的逻辑模型,重点阐述模型的各个组成部分及其中的信息流程,二是思想库政策影响力类型,具体包括直接性影响力和渗透性影响力两个大类。最后对该框架的特点做简要分析。     

Superconductivity in One-atomic-layer Metal Films

Superconductivity is a peculiar quantum phenomenon which originates from the pairing of conduction electrons, followed by phase coherent condensation. Since the discovery by K. Onnes in 1911, superconductivity has been one of the hottest topics in physics for an entire century, and still attracts people’s great interest. One of the intriguing issues is how     

Studies of Solar Vector Magnetic Field

In this article,we report a few advances in the studies based on the solar vector magnetic field observations which were carried out mainly with the Solar Magnetic Field Telescope at the Huairou Solar Observing Station in the 1990s.(1) We developed necessary methodology and concepts in vector magnetogram analysis(Wang et al.1996).For the first time,we proposed to use the photospheric free magnetic energy to quantify the major flare productivity of solar active regions(ARs),and it had been proved to be the best parameter in representing the major flare activity.(2) We revealed that there was always a dominant sense of magnetic shear in a given AR(Wang 1994),which was taken as the premise of the helicity calculation in ARs;we made the first quantitative estimation of magnetic helicity evolution in ARs(Wang 1996).(3) We identified the first group of evidence of magnetic reconnection in the lower solar atmosphere with vector magnetic field observations and proposed a two-step reconnection flare model to interpret the observed association of flux cancellation and flares(Wang and Shi 1993).Efforts to quantify the major flare productivity of super active regions with vector magnetic field observations have been also taken.     

Solar Coronal Mass Ejection as a Result of Magnetic Helicity Accumulation in the Corona

Coronal mass ejections（CMEs） are a major form of solar activities.A CME takes away 10^15-16 g of plasma from solar low corona,to disturb the near-Earth space if the CME direction is favorable.Here we summarize our understandings and reasoning that lead us to conclude that CMEs are the unavoidable products of magnetic helicity accumulation in the corona.Our study puts the formation of magnetic flux ropes and CME eruptions as natural and unavoidable results of coronal evolution.
