我国西部地区大气环境腐蚀性及材料腐蚀特征

萧以德; 王光雍; 李晓刚; 林安; 张三平; 秦晓洲; 王振尧; 梁彩凤; 郑弃非; 毛海荣

我国西部地区地形、地貌复杂、气候多变,按气候因素及环境条件,大致可分为酸雨、沙漠、高原和热带雨林4大类典型大气环境.各类环境的大气腐蚀严酷性是不同的.不同环境类型对材料的腐蚀(老化)破坏特点也不一样.酸雨大气明显加剧了金属、金属保护性涂(镀)层、建筑材料等的腐蚀破坏、沙漠大气环境虽然干燥、少雨,但对处于塔里木盆地的塔克拉玛干沙漠地区,由于空气尘降物中的盐类物质较高,Cu、Zn、Al、不锈钢及金属涂层的腐蚀破坏比中、东部的湿热、亚湿热城市大气反而严重.在高原环境下,高分子材料的迅速老化破坏是其显著特征、热带雨林大气环境的特点主要表现在光学仪器、皮革、织物、木材等的严重霉变.

兰州地区居民室内氡浓度水平调查

吴敏; 陈军军; 刘向荣; 冯晓妍; 陈雄

氡普遍存在于我们的生活环境中,氡的辐射剂量约占天然辐射剂量的一半。ICRP50号出版物估计公众肺癌的10%归因于氡及其子体照射。为了解兰州地区各类房屋中氡的水平,笔者于2001至2003年对兰州市普通居民住宅室内氡浓度进行了调查。兰州市位于甘肃省的中部,地处东经103°30’-104°30’,北纬35°35’~37°10’面积为14000km^2。北靠武威地区,西界青海省,西南接临宁夏回族自治州,东部邻定西地区。大部分地区被黄土所覆盖,是黄土高原的西北部。海拔一般为1500-2000m。全市主要为山地、半山地、河川等类型,其中山地占全市面积65%。
