利用自动型尘埃颗粒激光计数器和Anderson采样器,对成都市城东区两次浓雾天前后颗粒物的总数密度和质量分别进行了分析,得到颗粒物的物理变化特征,结果表明,浓雾的存在可以改变颗粒物的物理特征:颗粒物总数密度保持在270 000~310 000/100 cm3之间,粒径0。
In addition, the characteristics of burst reinforcement are analyzed on the three dense fog processes (time: December 12~(th)、14~(th) and 24~(th)-27~(th)), and some reasons ab.
辐射雾和平流辐射雾都是在晴空微风的夜晚辐射降温条件下形成的，锋面雾在锋面天气下形成和维持，并伴有小雨；辐射雾出现双层雾结构，具有明显的日变化特征，常在日出后随着太阳辐射加强而消散；12月24-27日的浓雾呈现出一些罕见的特征：雾顶高、雾层厚、维持时间长，主要是由于其逆温层深厚、大气层结稳定、风向风速适宜，暖湿气流的不断补充等作用的结果，北方冷空气南下造成的大风降温天气是这场大雾消散的直接原因；锋面雾产生于锋面天气下冷暖空气交界处，上空暖而湿的雨滴降落到下空冷而干的空气中，蒸发使得下层空气达到过饱和而凝结成雾滴，随着冷空气加强和上下湍流的增强锋面雾逐渐减。

南岭山地的浓雾伴随的降水,其雨水中的诸离子浓度远低于雾水中的值,因而,雾不但造成视程障碍,而且是高浓度污染的微粒,对人体健康十分有害。
In order to determine whether the leakage current during the flashover process has chaotic characteristics, the experiments simulating the insulator flashover in heavy fog were carried out and the chaotic analysis method of time series was selected to analyze the non-linear properties of leakage current in accordance with the flashover process.
首先针对绝缘子在灾害性浓雾天气下容易发生的闪络事故,通过观察闪络现象与过程,对闪络发展各个阶段的泄漏电流进行时间序列的混沌特征判别,计算和分析了Lyapunov指数、分形维数、功率谱密度、吸引子相图以及Poincare截面,论证了泄漏电流具有混沌特征,阐明了泄漏电流递归分析方法应用于绝缘子泄漏电流非线性特征分析的可行性。
