| 摘 要： | 对不同时空条件下的金华市二环以内的街道灰尘样品的磁化率进行了研究.结果表明,金华市街道灰尘磁化率均值349.67×10-8 m3/kg,冬、春、夏各个季节的平均值:322.55×10-8 m3/kg、358.16×10-8 m3/kg和368.31×10-8 m3/kg,指示了其均具有磁性增强效应,且其值相近;春、夏两个季节街道灰尘磁化率的高值区分布结构相似,模型参数分析表明,区域因素为影响其值的主因;街道灰尘磁化率高值区与城区工业区大体吻合分布,工业区是主要的区域因素。

| Abstract: | Magnetic susceptibility of street dust samples of different time and space within jinhua second ring road were studied. Results show that average magnetic susceptibility of street dust in Jinhua City is 349.67×10-8 m3/kg, and those in Winter, Spring, and Summer are 322.55×10-8 m3/kg, 358.16×10-8 m3/kg, 368.31×10-8 m3/kg, respectively, not different much, but indicating magnetic enhancement effect. In the three seasons, distribution structures of magnetic susceptibilities of street dust of high value areas are similar. Model parameter analysis shows that regional difference is the main factor to magnetic susceptibility. Areas of high magnetic susceptibility of street dust are general industrial areas of the city. |
