Wuhan National High Magnetic Field Center (WHMFC) at Huazhong University of Science and Technology is one of the top-class research centers in the world, which can offer pulsed fields up to 90.6 T with different field waveforms for scientific research and has passed the final evaluation of the Chinese government in 2014. This paper will give a brief introduction of the facility and the development status of pulsed magnetic fields research at WHMFC. In addition, it will describe the application development of pulsed magnetic fields in both scientific and industrial research.

为了提高在线喇曼光谱仪在芳烃装置的组分检测中的实时性和精度, 采用偏最小二乘法(PLS)结合粒子群算法(PSO)建立了预测模型。对一定的芳烃样品进行试验。先通过光谱仪获得芳烃成分的喇曼光谱, 再运用PLS算法对喇曼数据进行主因子提取, 从而降低数据间的冗余性, 然后应用PSO算法对芳烃组分含量进行快速搜索, 找到最优解, 最后将样品的真实值与预测值进行相关性分析。结果表明, 与传统方法相比, 喇曼光谱结合PSO算法和PLS算法的模型具有精确度高、分析速度快的特点。该研究为芳烃装置中组分的检测提供了新方法。
