The reaction process in methanol solvent can be deduced from the computational results with CPCM solvent model and the supermolecular handling, namely the reaction involves four steps in the methanol solvent. The nucleophilic addition of trimethylamine to acraldehyde generates an enolate. Nucleophilic attack of the enolate on the aldehyde forms the carbon-carbon bond, followed by the proton-transfer process and the further elimination generating the product and liberating the trimethylamine catalyst.

对于CH3OH对反应体系的影响，可以综合考虑CPCM溶剂模型及超分子模型下的研究结果，即CH3OH溶剂中反应按四步进行，催化剂三甲胺首先与丙烯醛发生亲核加成，生成的两性离子中间体与甲醛发生类似于Aldol的醛醇缩合，形成碳-碳键，之后发生分子内质子转移，最后经E1cb消除得到产物，并释放催化剂三甲胺。

空间环境通过各种效应(如磁暴、太阳质子事件等)对在轨航天器的安全运行及航天员的健康构成了严重的威胁，对依赖于天基手段的通信、导航定位、军事侦察、目标识别、气象观测、资源勘探等等均有重要影响。

The charge-remote fragmentation of protonated alkylamines and the fragmentation of alkylamine ions can be explaned by using the radical mechanism and hydrogen abstraction of intramolecule, respectively.

自由基机理可以解释质子化脂肪胺分子的远电荷反应。分子内氢抽取可以解释脂肪胺分子离子的碎裂反应。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
