由此肉桂油β-环糊精包合物成功解决了肉桂油易挥发，遇光和热不稳定，难用于工业生产这一难题，提高了其稳定性，制成固体剂型，为肉桂油的开发利用奠定基础。

The volatile solvent crystallization of 3-nitro-1, 2, 4-triazol-5-one on glass substrate was studied. The observed phenomena verify that the crystal morphologies change from fractal to cube-shaped structure due to the initial concentration increasing, and it can be explained with diffusion limited aggregation theory.

用扫描电镜研究了3-硝基－1，2，4-三唑－5-酮溶液在玻璃基片上挥发结晶行为，观察到随着NTO溶液的初始浓度升高，其晶体形貌从分形结构转变为立方状结构，并用扩散受限模型解释这一现象。

We used a Mode l PS-1 PUF Sampler (Graseby GMW, Village of Cleves, OH, USA) to collect samples of total suspended particulate and n-alkanes in the gas phase. Particles were collected on quartz fiber filters. Gaseous n-alkanes were adsorbed by PUF and XAD-2 in a cartridge placed downstream of the filter holder in the sampler.
