销量用英语翻译为"sales volume"。这个词来源于英语中的"sale"和"volume"，"sale"表示销售，"volume"表示容积、数量。所以销量就是指销售数量。

例句：

Our sales volume increased by 20% this quarter. (这个季度我们的销量增加了20%)

The company's sales volume has been declining for the past few years. (这家公司的销量在过去几年一直在下降)

The new product has been a huge success, with sales volumes reaching record levels. (新产品销量大增，创下历史纪录)
