马克思关于工业革命产生的世界历史条件思想及其现代启示

制度变革、资本积累、世界市场和需求的扩大、技术准备以及思想文化变革这五个相互联系的方面，构成了工业革命由以产生的世界历史条件系统，其中，“主导条件”是制度变革，而内驱力或精神动力则是观念变革。没有制度变革或制度变革不力，且精神动力“乏力”，“世界历史条件”系统中的其他因素和条件的发展及其作用就要受到极大的限制，从而整个“世界历史条件”系统就不可能获得最优化发展，即不可能朝着有利于催化工业革命的方向发展。马克思关于工业革命产生的世界历史条件的思想给予我们最重要的启示是：实现当代中国社会变革需要一系列的条件，但制度变革是其“主导条件”，观念变革是其精神动力。如果制度变革和观念变革严重滞后，就必然会严重地阻碍当前中国社会的变革，从而最终会导致这一变革的失败。据此，作者探讨了当代中国制度变革滞后的原因以及进行全面制度改革的出路问题，阐述了观念变革在当代中国社会变革中的重要性。     

初中生物教学要渗透人文精神

初中生物课程在人文精神的培养方面具有独特的价值.与物理、化学等其他自然科学相比,更具人文性.以往的生物教学,往往只注重生物知识的传授,就结构讲结构,就标本讲标本,却忽视了其人文教育功能.在初中生物教学中渗透人文精神有哪些突出作用呢?如何将人文精神渗透到教学中呢?本文拟就这两个问题作点探讨.     

论萨特的自由观及其对当前学校道德教育的启示

萨特的自由观以自由、选择与责任为核心,其自由观中对个体生命存在创造性、超越性的积极肯定,对个体自由能动的选择和勇于承担责任的强调对当前我国学校道德教育有以下启示:关注生命存在,提升生命意义;树立选择意识,增强选择能力;加强责任教育,培养责任意识,使道德教育实现由"教会顺从"向"学会选择"的转变。     

论高校可持续发展与战略管理

高校制定战略规划、推进战略管理,是应对内外部环境的变化,使其融入全球教育市场和参与国际竞争,提高可持续发展能力的必然性选择。高校在推行战略管理的过程中,应根据自身的特点,将战略规划、战略实施和战略评价等环节有机地结合起来,特别要重视战略实施。     

试论农村和谐社会的构建——农村民主政治建设面临的问题及对策

农村民主政治建设，是构建和谐农村社会的关键因素之一。当前。我国农村的民主政治建设进程中出现了村党支部与村委会、乡政与村治、村治机关与村民等一系列的矛盾。村民自治的家族化倾向也开始出现。这些不和谐因素的出现，有其深刻的体制原因、历史原因。也有村治机关自身的原因。从法律上界定村委会与村党支部、乡政与村治的权力界限，大力发展市场经济，健全村民自治制度等是消除这些矛盾，实现农村民主政治和经济社会和谐发展的重要措施。     

高校思想政治教育成本及其控制

高校思想政治教育和其他工作一样也是有成本问题的。本文提出了高校思想政治教育成本的概念，初步探讨了高校思想政治教育成本及其控制理论，以期高校思想政治教育工作者在实际工作中能努力降低“成本”。提高高校思想政治教育的效益。从而更好地实现高校思想政治教育的价值和目标；     

A 155 Mbps laser diode driver with automatic power and extinction ratio control

An integrated laser diode driver(LDD) driving an edge-emitting laser diode was designed and fabricated by 0.35 μm BiCMOS technology. This paper proposes a scheme which combines the automatic power control loop and temperature com-pensation for modulation current in order to maintain constant extinction ratio and average optical power. To implement tem-perature compensation for modulation current,a novel circuit which generates a PTAT current by using the injecting base current of a bipolar transistor in saturation region,and alternates the amplifier feedback loop(closed or not) to control the state of the current path is presented. Simulation results showed that programmed by choice of external resistors,the IC can provide modu-lation current from 5 mA to 85 mA with temperature compensation adjustments and independent bias current from 4 mA to 100 mA. Optical test results showed that clear eye-diagrams can be obtained at 155 Mbps,with the output optical power being nearly constant,and the variation of extinction ratio being lower than 0.7 dB.     

Study on hydrodynamic vibration in fluidic flowmeter

The characteristics of the fluidic flowmeter,which is a combination of impinged concave wall and bistable fluid amplifier,is investigated by experimental studies and numerical simulations. The numerical approaches are utilized to examine the time dependent flow field and pressure field inside the proposed flowmeter. The effect of varying structural parameters on flow characteristics of the proposed fluidic flowmeter is investigated by computational simulations for the optimization. Both the simulation and experimental results disclose that the hydrodynamic vibration,with the same intensity,frequency and 180° phase shift,occurs at axisymmetric points in the feedback channel of the fluidic flowmeter. Using the structural combination of impinged concave wall and bistable fluid amplifier and differential signal processing technique,a novel fluidic flowmeter with excellent immunity and improved sensibility is developed.     

The limit analysis in soil and rock： a mature discipline of geomechanics

The solution of a slope stability problem can be approached by its least upper-bound and maximum lower-bound with high accuracy. The limit equilibrium methods that employ vertical slices imply a lower bound of the factor of safety. It has been successfully extended to the area of active earth pressure analysis that accounts for different input of locations of earth pressure applications. Those methods that employ slices with inclined interfaces give an upper-bound approach to the stability analysis. It enjoys a sound mechanical background and is able to provide accurate solutions of soil plasticity. It has been successfully extended to the area of bearing capacity analysis in which various empirical coefficients are no longer necessary. The 3D upper- and lower-bound methods under this framework have been made possible and show great potential for solving various engineering problems.
