"This wall of air is a non-aggressive solution, which should work," Antonio Paolucci, a senior museum official in the central city of Florence told a news conference. a news conference前是不是省略了介詞，什么介詞，可以省嗎

沒有。a news conference 是新聞發(fā)布會(huì)。這是習(xí)慣用法。你可以將新聞發(fā)布會(huì)看作是"somebody"。這句話的句式便是told somebody something。Something便是前面那些話了。

我覺得少了個(gè)介詞at

這里的conference是指商協(xié)會(huì)吧？

不是的這就是用名詞修飾名詞，名詞也可以做定語(yǔ)
