Research on identification method of bituminous coal based on terahertz time-domain spectroscopy
Published 2025-04-01“…The two types of bituminous coal samples were detected by the transmission terahertz time-domain spectroscopy system, and the spectral data of various bituminous coal samples were obtained, and then the absorption coefficient and refractive index of each sample were obtained after mathematical calculations such as fast Fourier transform (FFT). The results show that the PCA-CA classification model based on terahertz absorption coefficient spectrum can accurately identify different bituminous coals with an accuracy of 100%, while the PCA-CA classification model based on refractive index spectra cannot accurately identify different bituminous coals. …”

Integrated Foliar Spraying Effectively Reduces Wheat Yield Losses Caused by Hot–Dry–Windy Events: Insights from High-Yield and Stable-Yield Winter Wheat Regions in China
Published 2025-05-01“…These HDW events were classified according to daily duration into three categories: short-duration (HDW<sub>sd1</sub>, 1 h d<sup>−1</sup>), moderate-duration (HDW<sub>sd2</sub>, 2–3 h d<sup>−1</sup>), and prolonged-duration (HDW<sub>sd3</sub>, 4–8 h d<sup>−1</sup>). Finally, a difference-in-differences (DiD) approach combined with panel matching methods was employed to quantitatively assess the effectiveness of integrated foliar spraying technology—comprising plant growth regulators, essential nutrients, fungicides, and insecticides—on wheat yield improvements under varying irrigation conditions. …”
