influx n.
释义：the arrival of large numbers of people or large amounts of money, goods etc, especially suddenly
“influx”是可数名词，意思是“大量涌入”。它后面接的对象比较有限，一般是人、资金、商品等。这个词的特点是它的表达准确，可以突出大量和集中。
虽然 influx 本身就有“大量涌入”的意思，不过也常和形容量级的形容词搭配使用，比如 great/massive/huge。
例① 欧洲国家最近几年都在头疼怎样应对大量涌入的中东难民，我们就可以说：
European countries have been troubled in recent years as to how to handle a great influx of refugees from the Middle East.
例② 现在印度互联网市场发展迅猛，很多中国投资人开始投资印度，因此印度有大量资本涌入。
