色谱分析是常用的现代仪器分析手段。高等院校仪器分析实验课程多将色谱分析列为主要教学内容之一。色谱分析包括气相色谱分析法和液相色谱分析法。气相色谱和液相色谱分析法具有相同点和不同点。基于比较教学法，在仪器分析实验课程中，分别使用气相色谱仪和液相色谱仪完成“苯、甲苯、间二甲苯的色谱分离”实验项目。在教学中，对比气相色谱分析方法和液相色谱分析方法的原理、实验条件、操作方法、实验结果等，从而加深学生对理论课中色谱章节内容的理解和学习，同时也对学生以后的科研训练提供一定的帮助。

采用2种密度泛函方法对C₆S₆Li₆储氢性能进行了理论研究。C₆S₆Li₆动力学稳定，最多可吸附38个H₂分子，储氢密度可达20.213%。C₆S₆Li₆(H₂)₃₈的平均吸附能接近温和条件下可逆吸附氢气的标准(0.1~0.8 eV)。各种波函数分析表明，C₆S₆Li₆中Li的2s→2p电子跃迁和各带电原子的电场极化共同主导了C₆S₆Li₆对H₂的范德瓦耳斯作用。热化学计算表明，在77 K下，压力为0.1、2.5、5.0 MPa时，C₆S₆Li₆分别自发吸附6、32、38个H₂分子，并且在298.15 K能够完全释放，可逆储氢密度分别为3.846%、17.582%和20.213%。原子密度矩阵传播动力学模拟表明，C₆S₆Li₆(H₂)₃₈中被吸附的H₂分子大多可以在室温下脱附，并且母体结构保持稳定，不会坍塌。二聚体(C₆S₆Li₆)₂能够吸附53个H₂分子，储氢密度为15.014%，也适合在温和条件下可逆储氢。

Two density functional theory methods were employed to evaluate the H₂ storage capabilities of metallo-borospherenes TM₈B₆ (TM=Ni, Pd). Consequently, the superatoms Ni₈B₆ and Pd₈B₆, which accommodate 40 and 32 H₂ molecules, respectively, exhibit gravimetric H₂ uptake capacities of 13.134% and 6.562%, respectively. The average binding energies of Ni₈B₆(H₂)₄₀ and Pd₈B₆(H₂)₃₂ fall within the optimal range for reversible H₂ storage applications. The interactions between H₂ molecules and the parent structures were characterized using various wave function analysis methods. Polarization effects, alongside the Kubas mechanism, are pivotal to the adsorption of H₂ on TM₈B₆. Moreover, the investigations examine the effect of temperature on the H₂ storage capacity of TM₈B₆ at atmospheric pressure. Atom-centered density-matrix propagation molecular dynamics simulations confirm the reversibility of H₂ adsorption and desorption cycles. The thermodynamic analyses of the desorption behavior of H₂ molecules were conducted via a three-dimensional graph, plotted based on the relationship between the number of adsorbed H₂ molecules and temperature as well as pressure, revealing that the majority of adsorbed H₂ molecules can be released at 0.5 MPa and 358 K. Compared to the respective monomeric counterparts, the H₂ storage densities of (TM₈B₆)₂ dimers exhibit a slight reduction.
