美联储副主席Richard Clarida周五表示，美联储已经接近“中性利率”，未来加息将取决于经济数据。请看本报昨日的报道：

U.S. Federal Reserve policymakers Friday signaled further interest rate increases ahead, even as they raised relatively muted concerns over a potential global slowdown that has markets betting heavily that the rate-hike cycle will soon peter out.

报道中的peter out就是“逐渐减少到消失”的意思。例如：

The influx of Asian students to American universities may peter out.

亚洲学生的申请美国大学的人数可能会逐渐减少。
