铁路空调客车车厢内循环空气的紫外线消毒方案

在空调车厢的回风道内或空调装置内安装紫外线杀菌灯，是消毒载客车厢循环空气，防止SARS等呼吸道传染病车厢内空气飞沫传播的可行方案。空调装置的送风量、消毒效果和紫外线灯的数量、布置之间的关系及安全保障措施还应通过试验进行优化。

Lessons learned from a personalized travel planning (PTP) research program to reduce car dependence

Voluntary travel behavior change programs have been implemented worldwide since the late 1990s at a personal and community level. Most of the now completed programs were commissioned by local authorities to commercial firms, in an attempt to reduce private car use. In this context, the evaluation and review of the reliability of these policy measures have been at the core of most of the debates and studies in this field. In this paper, we describe the lessons learned from a research program funded by the Sardinian Government (Italy), aimed at testing a soft transport policy measure for reducing car dependence. In particular, the work reviews in detail the methodological approach and participants’ feedback on a personalized travel plan (PTP). After implementation of the soft measure, the PTP participants were divided into two groups depending on whether they had reduced car use or not, and separate analyses were conducted to highlight the factors underlying different behavior change decisions. General conclusions regarding the effectiveness of the PTP are beyond the scope of the present study.     

水泥砼路面沥青加罩层间接触条件不同时的力学响应分析

旧水泥混凝土路面进行沥青加罩时，加铺层与旧板的连续性对加铺后路面各结构层的力学特性，以及出现反射裂缝的可能性会有较大的影响。由于传统的多层弹性体系理论不能计算带接(裂)缝的路面结构。因此本文利用三维有限元的计算工具，分析了在车辆荷载作用下，水泥混凝土不同的沥青加罩结构，在层间接触条件不同时的力学响应，并得出一些有意义的结论。
