摘　　要：为解决疫情环境下本科生近代物理实验的操作安全性问题,设计了远程操作系统Ultralab和虚拟核实验相结合的远程虚拟核实验。学生通过Ultralab的管理功能预约好实验时间后,可在家、教室或宿舍远程完成虚拟核实验。通过对不同虚拟放射源241Am和239Pu的能量标定,确定alpha粒子的能量峰值和道址的线性关系,从而测出alpha粒子穿过薄膜时薄膜的厚度。Ultralab远程虚拟核实验,使实验教学的灵活度增强,老师和学生可不受疫情和场地的限制自如开展实验。更可使学生的自主性和创新性增强,通过灵活重构虚拟核实验的各种参量,可实现gamma粒子测量、beta粒子测量等多个虚拟核实验以及相关实验,以达到熟悉和掌握放射性粒子与物质相互作用规律的目的。In order to solve the safety problem for undergraduate students operating modern physics experiments in the epidemic environment,a virtual nuclear experiment combining the remote operating system Ultralab was designed.Students can complete virtual nuclear experiments remotely in the classroom or dormitory or anywhere after booking the experiment time through the management function of Ultralab.By setting two different virtual radioactive sources 241 Am and 239 Pu,the linear relationship between the energy peak value of the alpha particle and the track address is determined.In that way the thickness of the film could be determined by the energy loss of alpha particle passing through the film.Ultralab remote virtual nuclear experiment enhances the flexibility of experimental teaching.Teachers and students can carry out experiments freely without being restricted by the epidemic situation and site.It can also enhance students'autonomy and innovation.Through flexible reconstruction of various parameters of virtual nuclear experiments,multiple virtual nuclear experiments and related experiments such as gamma particle and beta particle measurement can be realized.The purpose of being familiar with and master the laws of radioactive particle interacting with matter is achieved.
