编辑《影响》这样的主题性杂志的主要吸引力之一是,它为在专家帮助下考察科学技术起主要作用的各种问题提供了机会。同时,从我们只能在企图说明一个典型问题的9篇或10篇文章中作肤浅探讨的意义上来说,它可能带给我们一定程度的挫折感。要举例说明这两种形成对照的感觉,没有比本期关于交通问题的讨论更好的了。原因很简单,这里包含的材料太吸引人了。 One of the main attractions of editing thematic magazines such as Impact is that it offers an opportunity to examine various issues that play a major role in science and technology with the help of experts. At the same time, it may give us a degree of frustration in the sense that we can only make a superficial discussion of nine or ten articles that attempt to illustrate a typical problem. To illustrate the two contrasting feelings, there is no better discussion than this issue on traffic. The reason is very simple, the material contained here is too attractive.
