试用假绝热过程说明焚风形成原理?

答案

参考答案:

气流越过山脉时,在迎风坡上升冷却,按干绝热直减率降温。当空气湿度达到饱和状态时,水汽凝结,气温就按湿绝热直减率降低,大部分水分在山前落下,过山顶后,空气沿坡下降,并按干绝热增温,这样过山后,当气流到达地表时,温度高,湿度小,形成一股干热的焚风。

     In the United States, headmasters and teachers discipline (惩罚) students in several ways. The teacher often

writes to or calls the students' parents. Sometimes students have to stay at school for one hour. If a student

behaves very badly, the headmaster can stop the student having classes. The student can't come to school for

one, two or three days. Mr. Lazarus, the headmaster of a middle school in Ohio, did not like to do so. When he

didn't let the students come to school, they were happy."A three-day holiday!" they thought.

     One day, a boy was in Mr. Lazarus' office. The boy was not behaving well in class. Mr. Lazarus telephoned

the boy's parents. "If you come to school with your son, I won't stop him having classes," he said. The boy's

father came to school and went with his son to every class. Other students looked at the boy and his father. The

boy was embarrassed. After that he behaved better. And, of course, other students behaved better, too. 

     Now headmasters all over the USA are trying Mr. Lazarus's idea. They too, think that students behave better

when parents come to school.
