I'm not familiar with a specific reference to 辽阳伦敦金、However, I can try to break it down:

* 辽阳 (Liaoyang) is a city in Liaoning province, China.
* 伦敦金 (Londongin) seems to be a transliteration of London gold.

Could you please provide more context or information about what you are referring to? Are you looking for information on gold trading or a specific gold product related to Liaoyang or London? I'll do my best to help.
