小麦自发生物光子辐射特性的功率谱分析
Power Spectrum Analysis of Wheat Kernels' Spontaneous Biophoton Emission
摘要
Abstract
Power spectrum analysis method was employed in the field of biophoton analytical technology. The power spectrum of the spontaneous biophoton emission signal, belonged to four classes of wheat, was calculated with autocorrelation function method. Three parameters, 3 dB bandwidth, spectral gravity frequency and power spectral entropy, were adopted to explain the features of the kernels' spontaneous biophoton emission signal. The results showed that the main components of the kernels' biophoton signal were focused on the low-frequency band below 0. 05 Hz. For different classes, the three parameters in wheat kernels were near while the amplitudes corresponding to the first two parameters were relatively different. The data analysis method, may be a novel idea in the application field of BPAT.关键词
