During the entire Road Campus Program, not only the students left the classroom for sultriness, but also more and more people stood in the aisle.在整个校园路举行期间，不仅没有同学因为教室的闷热而离开，反而越来越多人，站满了过道。

Based on the work of Robert Steadman, who published several seminal studies on the assessment of sultriness, the National Weather Service (NWS) then made operational what became the heat index.基于罗伯特·斯泰德曼(Robert Steadman)的工作——他发表过一些对以后发展有重大影响的有关闷热的研究，国家气象局(National Weather Service, NWS)接着使什么成为炎热指数变得可操作。
