| 摘 要： | 本文针对测量得到六个不同品种小麦籽粒的延迟发光信号进行分析、处理，得到延迟发光初始强度和衰减系数等时域特征参数以及峰值点频率和频谱重心频率等频域特征参数。对比不同品种小麦籽粒的这些特征参数，发现品种不同，其各项参数取值也有较为明显的差异。本研究为小麦籽粒品种的快速、无损判定提供了一个新的思路。

| Abstract: | In this paper, the delayed luminescence characteristics of different varieties of wheat grain are researched. The delayed luminescence signals of six different varieties of wheat grain are measured firstly. Then they are analyzed and processed respectively, and then their time domain characteristic parameters such as initial intensity and attenuation coefficient, and frequency domain characteristic parameters such as peak frequency and spectrum center frequency are gotten. Through comparing the characteristic parameters of different varieties of wheat grain, we find that different varieties have its evident different parameters values. This paper provides a new idea to determine varieties of wheat grain in rapid and nondestructive way. |
