针对未建立CPⅡ、CPⅢ精测网的既有铁路,为了能快速、有效进行轨道不平顺性消缺,以提高轨道平顺性和线路运营水平,需寻找一种新的解决方法。本文通过深入研究惯导系统在航偏角与俯仰角方向的偏差误差,发现高精度惯导系统在缺乏CPⅡ、CPⅢ控制网约束情况下也能满足有砟铁路轨道不平顺性消缺;同时,采用双里程计设计,提高了里程测量精度,为大机捣固提供准确的里程基准。研究结论:(1)提出的既有线有砟铁路轨道不平顺性的消缺方法,无需依赖CPⅡ、CPⅢ控制网,为既有线有砟铁路轨道不平顺性的消缺提供基准数据,仍可快速测量

对青少年开展气候变化教育是应对气候变化挑战的重要举措之一。了解哪些因素会影响青少年的气候变化减缓意愿及行为则是开展有效气候变化教育的前提。文中基于影响青少年气候变化行为因素的理论框架,针对厦门、深圳、宁波9所中学1539名学生,开展问卷调查。结果表明,我国沿海地区12~14岁青少年整体上对气候变化关注程度和气候变化减缓行动表现一般,且其气候变化科学知识水平相对较低;回归分析显示影响他们减缓行为意愿的主要因素是过去参与过的气候变化减缓行为、自我效能和气候变化卷入度,而影响他们减缓行为的主要因素为气候变化卷入
