学生学习动机的缺失、培养与激发

现有的教育体制、现行高职教育的培养模式以及高职院校毕业生就业难的现实,直接导致学生学习动机不足乃至缺失。必须通过人才培养模式、课堂教学模式以及实习实践模式的创新,充分发挥高职院校教师的主导作用,培养和激发高职学生的学习动机。     

Upgrading Computational Design

Shajay Bhooshan heads up the computation and design ZHACODE group at Zaha Hadid Architects (ZHA) and is a course master at the Architectural Association Design Research Laboratory (AADRL). Here he argues that Parametricism 2.0 has a vital role to play in the progressing of computational design. Assimilating the exploratory developments of the last 15 years, he asserts how the next phase of Parametricism will enable a further consolidation and evolution of digital practices.     

Architectural Patents and Open-Source Architectures: The Globalisation of Spatial Design Innovations (or Learning from ‘E99’)

Patents are the strongest form of intellectual property rights available internationally, so far unbeaten by open source as a body of innovation and know-how. Mark Garcia , senior lecturer in the Department of Architecture & Landscape at the University of Greenwich, London, here considers the pros and cons of the patent system for architects in the digital age: from issues over patent categorisation by type, to possibilities of micro-royalties through the capacity of design software to track every stage of input from multiple contributors.     

Design for the Future: Educational Institutions in the Gulf

Despite a distinguished heritage of learning in the Middle East, the expansion of provision for higher education is currently at an unprecedented scale. The Gulf States, in particular, are seeking to keep up with accelerated population growth and a demographic ‘youth bulge’. Guest-Editor Kevin Mitchell describes the architectural approaches employed in the design of institutions in the region from the first universities in Saudi Arabia to Foster + Partners's ground-breaking sustainable design for the Masdar Institute in Abu Dhabi and future projects.     

In the Pursuit of Pleasure: The Not so Fleeting Life of the Pavilion and its Ilk

Author and architecture critic for the London Evening Standard, Robert Bevan reflects on the enduring appeal of the temporary structure, speaking ‘to a latent desire for freedom and movement’ as a hangover of our nomadic past in a sedentary ‘civilised’ society. He highlights the type's historical apex in Henry VIII's palatial pop-up on the Field of the Cloth of Gold, questioning the purpose and purposelessness of more recent examples.     

用于电磁干扰分析的共模扼流圈高频模型

共模扼流圈的高频特征极大地影响了电磁干扰（EMI）滤波器抑制传导EMI噪声的性能.为了准确地评估和预测EMI滤波器的性能，提出了一种基于150 kHz～30 MHz阻抗测量的共模扼流圈高频建模方法，建立了可用于EMI性能分析的差模模型和共模模型.采用Foster网络来表示共模模型参数随频率而变化的特征，并且通过一个实例给出了共模扼流圈的高频集总参数模型.通过比较共模扼流圈插入损耗的测量结果和仿真结果，证实了所提出的共模扼流圈高频建模方法的可行性.
