论毛泽东关于社会主义矛盾学说的创立及其意义

在《关于正确处理人民内部矛盾的问题》一文中,毛泽东从哲学高度指出了社会主义社会存在两类性质不同的矛盾,首次创立了关于社会主义社会矛盾的学说,本文将以全新的视角,解读其重大理论意义和实践意义,深入研究其理论价值,从而为当代中国构建社会主义和谐社会和全面建设小康社会提供理论支撑．     

Microwave permeability of single cobalt nanotube studied by micromagnetics simulations and generalized Snoek’s law

Microwave permeability spectra of single Co nanotube under equilibrium state have been studied by micromagnetics simulation.More than four obvious resonance peaks have been found(11.72,24.20,33.18 and 39.55 GHz).Such large resonance frequency cannot be found in other traditional magnetic materials.The configurations of magnetic moments along the nanotube have been simulated.The results show that the top end of nanotube has a"flow-out"pattern of magnetic moments configuration.The bottom end has a"flow-in"pattern of magnetic moments configuration.The magnetic moments within the main body of nanotube are aligned perfectly along the length of nanotube.The magnitude of natural resonance peak is strongly related to the volume fraction of a zone,which has the same orientation of magnetic moments.Large microwave permeability values have been found for single nanotube.The generalized Snoek’s law has been used to validate the micromagnetics simulations in this paper.     

我国刑事被害人权利保护在执法上存在的缺陷及其完善

目前，我国刑事被害人的权利保护状况已得到了很大的改善，然而，在执法实践中公安司法机关对被害人权利的保护仍存有许多缺陷，包括立案、侦查直至审判、执行等诉讼环节都还有系列需改进之处。针对执法之现状，我们必须采取有效措施去加以完善。     

Artificial argument assistants for defeasible argumentation

The present paper discusses experimental argument assistance tools. In contrast with automated reasoning tools, the objective is not to replace reasoning, but to guide the user's production of arguments. Two systems are presented, and based on . The focus is on defeasible argumentation with an eye on the law. Argument assistants for defeasible argumentation naturally correspond to a view of the application of law as dialectical theory construction. The experiments provide insights into the design of argument assistants, and show the pros and cons of different ways of representing argumentative data. The development of the argumentation theories underlying the systems has culminated in the logical system that formalizes the interpretation of prima facie justified assumptions. introduces an innovative use of conditionals expressing support and attack. This allows the expression of warrants for support and attack, making it a transparent and flexible system of defeasible argumentation.     

陆良与保山盆地第三系浅层气田开发规律探讨

以云南陆良、保山盆地第三系浅层气田为例,结合国内外浅层气田的开发经验,探讨浅层气田的开发规律,以指导同类气田的开发.浅层气田一般气藏规模小,气柱高度小;产层疏松,大部分气藏为有水气藏;生产时气藏无水生产时间短、稳产时间短,气井容易出水、出砂,其开发规律明显区别于中深层整装构造型气藏.针对陆良、保山浅层气田生产表现的"三低"(低单井日产水平、低采气速率、低采出程度),气井见水快,井筒容易积液,产层容易出砂,出水大则出砂也大等特点,提出以下对策:(1)依据多井小压差原则,进一步完善井网,避免频繁激动气井;(2)严格按.规定压差生产,及时确定气井"三稳定"的最佳工作制度,生产中;(3)尽量减少或杜绝井口气量调节,更不能轻易关井;(4)一旦发生气井水淹,尽快采取措施,避免造成井底或地层的严重污染,给复产带来困难;(5)加强气田生产测井、试井、产能测试,取全取准各项资料,及时进行动态分析与动态监测,对生产中出现的问题做到早发现、早解决.从而保证气田平稳、正常开采.     

Analytical Model Development for Stokes-Type Settling in a Solidifying Fluid

Analytical modeling was used to track the mudline displacement of a simulated fluid dispersion that underwent a simulated linear increase in the fluid viscosity as a function of time following an induction period. Modeling results indicate two regimes of settling behavior from the driving force of density differences between the particles and the fluid. A linear mudline movement was first determined in the regime of constant viscosity, and a logarithmic retarded mudline movement was numerically determined following a linear rise in fluid viscosity. The results show that the combination of settling and solidification leads to a transitional mudline movement similar to batch settling curves described by early settling theories.

Radionuclides in primary coolant of a fluoride salt-cooled high-temperature reactor during normal operation

The release of fission products from coated particle fuel to primary coolant,as well as the activation of coolant and impurities,were analysed for a fluoride salt-cooled high-temperature reactor (FHR) system,and the activity of radionuclides accumulated in the coolant during normal operation was calculated.The release rate (release fraction per unit time) of fission products was calculated with STACY code,which is modelled mainly based on the Fick's law,while the activation of coolant and impurities was calculated with SCALE code.The accumulation of radionuclides in the coolant has been calculated with a simplified model,which is generally a time integration considering the generation and decay of radionuclides.The results show that activation products are the dominant gamma source in the primary coolant system during normal operation of the FHR while fission products become the dominant source after shutdown.In operation condition,health-impacts related nuclides such as 3H,and 14C originate from the activation of lithium and coolant impurities including carbon,nitrogen,and oxygen.According to the calculated effective cross sections of neutron activation,6Li and 14N are the dominant 3H production source and 14C production source,respectively.Considering the high production rate,3H and 14C should be treated before being released to the environment.
