大众传媒对青少年价值取向的负面效应及其对策

大众传媒对青少年价值取向的导向功能，既有积极的正面导向，也有消极的负面导向。大众传媒所宣扬的实用主义、享乐主义、拜金主义、爱情至上等负面价值导向因素，对当代青少年的价值取向产生一定的消极影响。限制和消除大众传媒对青少年价值取向的负面效应，必须纠正人们思想认识上的误区，强化政府的调控手段，发挥家庭教育、学校教育的作用以及重建新的道德价值观念体系。     

Too Much,Too Young? An Analysis of the Key Stage 3 National Literacy Strategy in Practice

This article was first drafted after I worked for 14 weeks last year in a school that was piloting the National Literacy Strategy at Key Stage 3. I now work in another school delivering the full published Strategy to Year 7. In this article, I explore the contradictions inherent in the Strategy in attempting to develop the English and literacy skills of Key Stage 3 pupils. Ultimately, my argument is that the educational benefits of this teaching to objectives is at odds with some of the deeper aims of the Strategy and of English teaching, and that the constant assessment involved puts too much pressure on our youngsters at an age when they should be concentrating on social development as people.     

通过串音预测对PCB布线的3W规则进行验证

在传输线理论的基础上，利用有限元(FEM)法计算分层介质中微带线上场的分布，并通过SPICE仿真对其等效电路在不同频率电源激励下产生的串音进行预测．预测结果验证了印制电路板布线遵从“3W”规则的重要性．由此得出结论：3W规则的使用有功于PCB设计满足EMC系统设计标准，并最大限度地减小印制线之间的耦合．     

Pattern design on 3D triangular garment surfaces

This paper focuses on a pattern design method for a 3D triangular garment surface. Firstly, some definitions of 3D style lines are proposed for designing the boundaries of patterns as drawing straight lines or splines on the triangular surface. Additionally some commonly used style lines are automatically generated to enhance design efficiency. Secondly, after style lines are preprocessed, a searching method is presented for quickly obtaining the boundaries and patches of a pattern on the 3D trian- gular surface. Finally a new pattern design reuse method is introduced by encoding/decoding the style line information. After style lines are encoded, the pattern design information can be saved in a pattern template and when decoding this template on a new garment surface, it automates the pattern generation for made-to-measure apparel products.     

Numerical Calculation of Concrete Slab Response to Blast Loading

In the present paper, a dynamic plastic damage model for concrete has been employed to estimate responses of a reinforced concrete slab subjected to blast loading. The interaction between the blast wave and the concrete slab is considered in 3D simulation. In the first stage, the initial detonation and blast wave propagation is modelled in 2D simulation before the blast wave reaches the concrete slab, then the results obtained from 2D calculation are remapped to a 3D model. The calculated blast load is compared with that obtained from TM5-1300. Numerical results of the concrete slab response are compared with the explosive test carried out-in the Weapons System Division, Defence Science and Technology Organisation, Department of Defence, Australia.

SrTiO_3微晶玻璃的低温制备及性能

采用低温法制备出SrTiO_8微晶玻璃.对样品进行了X-射线和DTA及ε-T曲线的测定。结果表明,在样品用料中加入一定量的碱金属氧化物,可以在较低温度下(～1350℃)制得SrTIO_8微晶玻璃。碱金属加入量的多少直接影响到微晶玻璃的制成温度.在较低温度下制得的微晶玻璃的介电常数随SrTiO_3含量的增加而增加,随温度的升高而略有升高。     

论如何提高高校排球专选课的教学效果

排球运动在我国高校中开展的非常广泛,然而传统的教学方式存在种种弊端,制约了排球专选课的教学效果,因此有必要对增强排球专选课的教学效果做出探讨.     

上海居民教育消费增长因素与效应的实证分析

上海居民教育消费自20世纪90年代以来快速增长,目前已达到相当高的水平。其影响因素除经济发展和居民收入水平提高以外,还有高校扩招、民办学校的发展、教育收费制度的改革以及居民教育消费的价值取向等等。教育消费的迅速增长在宏观上具有显著的积极意义,但也会对居民的其他消费产生挤出效应,而且过度教育消费可能导致结构性过度教育、影响教育机会公平等社会问题,应该注重教育消费资源的管理,规范教育市场,引导居民进行理性教育消费,使教育消费尽快进入可持续发展的良性循环。     

钢琴四、五度与三、六度调律法

钢琴调律，精确度是不容忽视的问题。目前，调律师普遍采用的是四、五度调律法。但这种调律法的整个过程彼此依赖，形成一个闭合环，二旦某个步骤出现误差，将会带入下一环节，而三、六度调律法可减少人为误差，有助于提高调律的速度及精确度。
