In‐Place and In‐Time

This article presents parallel and collaborative research and teaching practices that expand approaches to encountering site through the lenses of observation and performative drawing. These drawing practices record phenomena, whilst in their presence, through a designed temporal framework. This asks the drawer to observe over a duration of time and to record the world in motion. By spending an extended period of time in the presence of the phenomenon of our study, with active receptivity, our capacity to see shifts. Rather than the drawn outcomes of this observation recording a past time, the notion of experiential time – and an expanded present – is embedded in the act of drawing. These processes of observation and performative drawing allude to Edmund Husserl’s expression of a ‘thickened present’. The outcomes of this drawing practice demonstrate that observational techniques are embodied, relational, temporal and generative and so offer an alternative approach to site analysis. How this approach sits within the larger domain of spatial temporal relationships and forms of drawing are also considered.     

大气污染对云冈石窟的风化侵蚀及防护对策

云冈石窟地区大气污染较为严重.大气中的污染物主要是SO2、工业粉尘及粉尘中的金属元素,其含量皆严重超标.在有水份的环境中,通过金属离子的催化作用,SO2容易生成H2SO4或酸性物质,再与石质文物表层中CaCO3作用,生成CaSO4*2H2O, 导致风化侵蚀.

大学英语四、六级统考笔试“新”题型补充

根据社会发展对大学英语教学的要求、根据对大学英语和英语专业英语教学大纲、考试大纲、历年四、六级试题以及现行大学英语和英语专业英语教材的研究,本文提出了大学英语四、六级统考可以补充的六种题型,期望能在更大限度上实现四、六级考试大纲所描述的各项测试目的,提高四、六级考试的效度,并通过测试的反拨作用更好地引导大学英语教学向《大学英语教学大纲》提出的培养目标靠近。尽管有些题型对目前的大学英语学生有些超前,但社会发展对大学英语教学与测试的要求会让它们有用武之地。

ANALYSIS OF MICROWAVE N-PORT NETWORK BY A MODIFIED BOUNDARY ELEMENT METHOD

A new approach based on resonance technique and modified boundary ele-ment method is presented to calculate the impedance parameter matrix of a microwaveN-port network of waveguide structure.A two port network is taken as a numerical ex-ample and the results show that the approach occupys the advantages of high accuracyand less computation effort.
