摘要： 如何测量结晶成核速率、理解晶体结晶动力学过程是晶体化学的学习难点。大气气溶胶颗粒，在高湿度条件下以液态存在，当环境相对湿度(Relative humidity, RH)降低至某个范围内时，颗粒物发生从液态到固态转变，这个过程被称作气溶胶的风化(Efflorescence),发生液-固相变时的RH被称 ...

摘要： 酸碱平衡是化学教学中十分重要的内容，而在目前的教学中仅仅描述了均相溶液中的酸碱解离与pH缓冲问题，并未描述多相体系中气相成分对体系酸碱解离与pH缓冲的影响。针对该问题，本文以典型的气溶胶多相体系为例，通过对多相缓冲理论和有效解离常数p K_a^*的分析，讨论了 ...

摘要： 硫酸盐是大气雾霾颗粒中一种重要的二次无机组分，但是有关大气硫酸盐生成机制的认识，目前还存在很多不足。同时，现有的空气质量模型也往往存在对硫酸盐生成量的低估问题，无法有效复现外场观测结果。因此，深入研究大气硫酸盐的生成机制，对理解雾霾成因、实现大气污染的精准防控具有重要意义。本研究利用光镊-受激拉曼光 ...
