目前视觉搜索的相关研究对细节关注甚少。安检是一项特殊的视觉搜索过程，了解其工作过程对改善其工作质量意义重大，因此，有必要对其细节进行研究。选取两组被试进行安检模拟实验，以研究现行安检原则“先难后易，先复杂后简单”的可行性以及两组被试视觉特征的差异。结合两组被试的特点，对数据进行了筛选、统计，运用非参数检验综合分析了两组被试实验数据的差异，并应用专家打分法分析两组被试视觉搜索过程的差异。结果表明，两组被试在注视时间百分比、眼跳距离、判断正确率上存在显著差异，安检员组的正确率比学生组高28．7％；安检员组的注视持续时间较短，有超过75％的注视点持续时间小于200ms，而学生组处于该时间段的注视点只占17％左右；安检员组在模拟实验中倾向于遵循安检原则进行系统搜索，而学生组倾向于随机搜索。

Currently, little attention is paid on the details of the research on visual search. Security screening is a special visual search process, and understanding this process is the premise of improvement. It is necessary to learn the visual search details in security screening. To test the rationality of the current security principle （from difficult to easy, from complex to simple） and the difference between the two groups, two groups （screener＇s group and student＇s group） are selected to conduct a screening simulation experiment. Based on statistical analysis, by combining with the characteristics of the two groups, a non- parametric test is applied to analyze the differences on some parameters. Expert grading method is used to analyze the searching process. Results reveal that there are significant differences on fixation time percent, saccade distance, and judgment accuracy between the two groups. The screener＇s correct rate is 28.7% higher than student＇s, while screener＇s fixation duration is shorter. There are more than 75% of the fixation points lasting for less than 200 ms, while student＇s is about 17%. The screener＇s group tends to do system- ic searching under the principle of screening, while the student＇s group prefers random searching.
