销量的持续增长带动比亚迪业绩进一步爆发，该公司预计三季度净利润同比增长至少67%。请看本报周四的报道：

BYD Co. expects third-quarter profit to rise at least 67% on the back of record electric vehicle sales.

Third-quarter net income will come in as high as 11.5 billion yuan (US$1.6 billion), compared with 5.7 billion yuan a year earlier, the Warren Buffett-backed maker of electric vehicles and batteries said in an exchange filing late Tuesday.

报道中的on the back of就是“由于（之前某项成就）”。例如：

The advertising agency secured the contract on the back of its previous successful campaigns.

由于前期的宣传工作富有成效，这家广告公司最终获得了合同。
