一个用于催化剂成冰性能检测的新型等温云室

A New 1m^3 Isothermal Cloud Chamber for the Study of Artificial Ice Nuclei

云雾物理实验是我国大气科学研究需要加强的一个方面,文中介绍了中国气象科学研究院新建用于人工冰核催化剂成冰性能研究的1 m3等温云室。阐述了该云室主要结构组成、性能特点、附属设备和实验程序,以及所开展的催化剂成冰效率的初步检测研究。实验结果表明,该云室在原建系列云室基础上,对制冷及保温性能有很大的改进和优化,更适合催化剂成冰性能检测和研究,为今后我国开展云雾、降水微物理实验研究和提高人工影响天气催化技术水平提供了一个有用的综合研究平台。

A new 1 m^3 isothermal cloud chamber mainly for ice nucleation study is described in this paper. Its structure, attached instruments and experimental procedures are also presented. The experiments of determining the artificial ice nuclei effectiveness for the AgⅠ-containing aerosols produces by three kinds of formulations have been conducted and the results have been compared with those of two burning rooms. All experimental results show that the chamber has advantages of stable performance and reproducibility. It would be expected to become a useful experimental facility for ice nucleation investigating in China.
