摘　　要：以"光谱测量实验"为基础,结合目前核脉冲处理领域的科研热点,设计一个综合型实验,在FPGA的脉冲处理单元中实施一种脉冲甄别技术,对不同时刻突变的脉冲及其成形结果进行甄别分析,从而筛选出需要剔除的脉冲。将脉冲剔除技术引入到光谱测量中。通过实验可以锻炼学生文献阅读的能力,使用MATLAB仿真软件模拟实际问题的能力以及通过实验装置验证仿真结果的能力。实践表明,在高校实验教学中引入行业最新的科研热点,不仅有利于激发学生的创新思维,也对学生的科研能力和综合运用能力具有良好的效果。Based on the"spectrum measurement experiment"and the current scientific research hot spots in the field of nuclear pulse processing,a comprehensive experiment was designed,In the pulse processing unit of FPGA,apulse screening technology is implemented to screen and analyze the distorted pulses and its forming results at different times,so as to screen out the pulse to be eliminated.The comprehensive experiment introduced the pulse rejection technology into the spectrum measurement.Through experiments,students′ability to read literature,and the ability to simulate practical problems by using MATLAB simulation software,as well as the ability to verify the simulation results through experimental devices can be exercised.Practice shows that the introduction of the latest research hot spots into undergraduate experimental teaching is not only conducive to stimulating students′innovative thinking,but also has a good effect on students′scientific research ability and comprehensive application ability.
