向高考看齐？

我国高考对平时测试有着巨大的影响力。本文从测试内容、测试题型和对测试的分析解释三个方面来看高考的影响。由于高考和平时测验的目的不同,因此它们在测试内容上应有所不同,平时测试应针对某一阶段教学而设计,不宜加重能力题的比重,但应在试卷中加大主观题的份量,以便全面反映学生的能力。最后,平时测试的结果分析也不宜采用常模参照,过分看重学生的成绩排名。总之,高考与平时测试的目的性质不相同,测试不应向高考看齐。

从美国大学科研经费的间接成本管理看政府与大学的关系

联邦资助的科学研究是今日美国研究型大学的突出特点。一般而言,联邦政府支付科研活动的全部费用,包括大学因承担科研项目而发生的间接成本。起源于二战时期政府资助大学的科研合同,间接成本制度自20世纪50年代以来逐渐发展完善,成为美国联邦政府资助大学科研活动的政策工具。透过间接成本制度可以揭示政府-大学关系在过去60年中的巨大变迁。

Shaking table test of pile-water-pier superstructure

The model test of seismic simulation shaking table is an important method to study the seismic design of bridge structure. In order to evaluate the seismic response and dynamic characteristics of pile-water-pier system for developing more reliable design procedures, shaking table model tests of a submerged bridge pier system, including pile groups-cap-pier and inertia mass, were conducted. Since different similitude laws corresponding to different test objectives affected the validity of test results, the similitude law with the aim to consider the effect of hydrodynamic pressure was proposed and confirmed through an actual example. Based on the test results, the effect of water around model on seismic response under seismic excitation input was analyzed and the failure level was judged by observing the variation of basic frequency. The test results indicate that the transfer function of analytical model with water is different from that without water, the natural frequency without water is always higher than that with water, and the first modal shapes are various. It is also concluded that the similitude law is suitable for practical application and the dynamic characteristics and seismic response of the structure system can be changed because of the existence of the surrounding water, which should be paid much attention in the further investigation.     

Numerical analysis of tensile bifurcation phenomenon of a film bonded to a substrate

To study the mechanical properties of the film/substrate structure, the finite element code ABAQUS v6.9-1 is adopted to simulate the tensile mechanical behavior of the nanoscale thin film bonded to a substrate. The bifurcation phenomenon of the structure under uniaxial tension is found: the single-neck deformation, the multiple-neck deformation and the uniform deformation. The substrate and the film are regarded as power-hardening materials obeying the J 2 deformation theory. Firstly, the influence of material hardening match on tensile bifurcation mode is analyzed under perfectly well-bonded interface condition. Then, the effects of interfacial stiffness and other superficial defects surrounding the imperfection on bifurcation mode are investigated. It is concluded that under the well-bonded interface condition, if the stress of the substrate is larger than the film, the film will uniformly deform with the substrate; if the stress of the substrate is smaller than the film, the film will form a single neck, except the case that a weakly-hardening film is bonded to a steeply-hardening substrate when multiple necks can be formed. With the decrease of interfacial stiffness, the uniform deformation mode can transform into the multiple-neck deformation mode, and further transform into the single-neck deformation mode. And other defects surrounding the imperfection can influence the wavelength of deformation and neck number.
