Hi shamen
welcome to idns, I am not a native chinese speaker but did run your domains to check baidu results.

your domain // Baidu # of searches
國際化.com international global) 0
电汇.cn telegraph) 0
貴金屬.com precious metals) 0
计算机科学.com computer science) 4,080
斯诺克.com snooker) 31,200
分享.tv file share) 16,020
撲滿.com piggy bank!!) 0

given the results I like snooker and files share. The only issue with file share is that is it a .tv. I have a handful of those in Chinese, I tried only get keywords that fit .tv extension. here are the baidu search results for some I thought might fit the extension better to give you an idea of the numbers.

might want to check a couple translations, or a native speaker might be able to help. Here is one translator I use.
