第一个合成染料——苯胺紫是在1856年由威廉·H·珀金(W·H·Perkin)发现的。差不多在100年之后,即1953年,帕里瑟(Pariser)和帕尔(Parr)以及波普尔(Pople)独立地创立了一种新的、革命性的分子轨道理论方法,即现在所谓的PPP-MO法。化学上这两块看似乎风马牛不相及的里程碑,都在表明理论化学是怎样为化学工业技术做出重大贡献的。在现代化学工业中,染料化学一直起着举足轻重的作用。在我们的生活中染料和颜料可以说是最为广泛的合成有机物质。继珀金的这一首次发现之后,染

This article reports the thermal ageing of ester fluid-impregnated pressboard material along with its performance evaluation using optical emission spectroscopy(OES)and classifi-cation using machine-learning algorithms adopting laser-induced breakdown spectroscopy(LIBS).The surface discharge analysis on ester-impregnated pressboard(EIP)is studied using OES and the plasma temperature was evaluated based on the Cu I emission lines which were higher under the negative DC compared with the positive DC and AC *** LIBS analysis was performed on the EIP material operated at different energy levels in order to acquire the optimal energy required to be used for its classification *** intensity ratio and electron density evaluated from LIBS studies correlated well with the plasma *** lower limit of detection(LOD)calculated based on linear regression analysis for copper peak was around 3.5 times higher than the identification of carbon *** machine-learning techniques like principal component analysis and neural network algorithm have been performed on the LIBS spectral dataset in order to classify the ageing of EIP *** neural network adopting LIBS provided a better classi-fication accuracy on all the aged samples compared with principal component analysis which classified only for the samples aged at higher temperatures.
