| Abstract: | The paper have detueed the theory formula of mercuty element determination of cold atomic fluorescent.The research work certre on the effection accury degree of detetined result by ten project element such as:a king of carrier gas; voltage of work;water vapour;acid degree of medium; redution expendition etc,determined optimum of experement condition,put forword the method of trace mercaty in the suface water and the soil.At the same time,it not only anilysed the systems error or reduce the system error of me mercary element determination method of cold atomic fluorescent,but so far as to be eliminated. |

| Keywords: | cold atomic fluorescent trace told mercary experiment condition of optimum determinational method anilysis of systems error |
