路透调查显示，受累于国内需求不振和中美贸易摩擦的不确定因素，八月份中国制造业连续第三个月减速。请看本报周五的报道：

Activity in China’s vast factory sector likely slowed for the third straight month in August as domestic demand remained weak and exporters faced rising uncertainties from the escalating trade dispute with the United States, a Reuters poll showed.

While the August manufacturing slowdown is expected to be modest, it will reinforce views that the world’s second-largest economy is continuing to lose steam even as the United States readies even tougher tariffs on Chinese goods.

That is likely to prompt China to roll out more growth boosting measures, adding to a spate of recent spending announcements, tax cuts and steps to lower companies’ financing costs.

报道中的lose steam就是“减速”的意思，例如：
