| 通过2018年1月的污染天和非污染天在上海人民广场地铁站对装有屏蔽门系统的1号线站台和装有安全门系统的2号线站台上的颗粒物数量浓度进行监测并作对比研究，结果表明：污染天和非污染天，安装屏蔽门系统的站台颗粒物数量浓度相对于安全门系统分别降低208%～3544%和569%～5131%。〖JP3〗屏蔽门站台的颗粒物浓度表现为后站台＞〖JP〗前站台＞中站台；安全门系统颗粒物浓度无规律。屏蔽门系统站台的颗粒物在人体内的沉积量要低于安全门系统，站台两端的颗粒物在人体内的沉积量高于站台中间。 |
| 英文摘要: |
| The quantity concentration of particulate matter on the platform of subway line 1 with screen door system and line 2 with safety door system were monitored during polluted and non polluted days in January 2018 at Shanghai Peoples Square subway station. The results showed that the quantity concentration of particulate on the platform with screen door system reduced by 2.08%～35.44% and 5.69%～51.31% than that with safety door system in polluted and non polluted days， respectively. The concentration of particulate on the platform with screen door from high to low in order was： at the rear， in the front and in the middle of the platform. The particulate concentration with safety door system was irregular. The amount of particulate matter deposited in human body on the platform with screen door system was lower than that with safety door system. The amount of particulate matter deposited in human body at the ends of the platform were higher than that in the middle. |
