【摘要】 采样点的布设在应急监测过程中起着至关重要的作用,科学、合理地布置采样点是应急监测的关键技术之一,采样点必须分布在整个事故影响区域。引入气体扩散模式预测事故影响范围,根据毒负荷标准在事故影响区内划分危险区。阐述了应急监测采样点布设原则及事故初期、中期、后期的特点,并对三个时期采样点布设方法进行研究。更多还原

【Abstract】 The setup of sampling spots plays an important part in the process of emergency monitoring.Scientific and logical setup of sampling spots is one of the pivotal skills of emergent monitoring.Sampling spots must be distributed among all accident influencing areas.The text imports gas pervasion mode to forecast the accident influencing areas,then compartmentalize danger zone on the base of poison load standards.The text expatiates principles of sampling spots setup in emergency monitoring,and characteristics of accident initial stages,metaphase and anaphase,also researches the methods of sampling spots setup in the three periods.更多还原
