在化工热力学实验教学中，通过设置进阶训练思考题，激励学生进行探索与实践。以第二维里系数的测定实验为例，倡导学生独立思考与构建高阶维里系数的方法，引导其分析比较国内外学者处理问题的策略与方法，而后辅导其通过双向检验证明所做实验数据的准确性、验证所构建方法的合理性、分析所得结果的有效性，最后指导学生理清数据处理方法的发展脉络，对其所构建的方法进行准确定位与评价。本教学实践通过强化实验教学项目的设计性与综合性，探索提升实验类课程高阶性的途径，践行“两性一度”的要求。

A unique 3D luminescent metal-organic framework, namely [Cd(L)(H₂O)_0.5]·DMF·2.5H₂O (1), where H₂L=3-(tetrazol-5-yl)triazole, has been successfully prepared and characterized. The framework has demonstrated excellent luminescence properties and structural stability in the water system. Notably, the luminescence intensity of 1 was significantly quenched by Cr(Ⅵ) (1 mL of Cr₂O₇^2- or 150 μL of CrO₄^2-, 1 mmol·L^-1), leading to the formation of an "on-off" luminescence silencing system (Cr₂O₇^2-@1), which was capable of accurately detecting Cr(Ⅵ) in the water system. The primary mechanism responsible for luminescence quenching was the Forster resonance energy transfer (FRET) process. Additionally, by removing the involvement of the FRET process, the luminescence intensity of the Cr₂O₇^2-@1 system could be restored, allowing for the highly selective and sensitive detection of ascorbic acid (AA) in water systems. Moreover, it has been demonstrated that 1 can successfully detect AA in vitamin C tablets, yielding recovery rates ranging from 98.20% to 103.33% and relative standard deviations (RSDs) ranging from 1.78% to 3.42%. Based on the findings of this experiment, a luminescent "IMPLICATION" molecular logic gate has been constructed utilizing AA and Cr(Ⅵ) as the chemical inputs, respectively.
