有的老师指出人民教育出版社初中物理教材第一册p．163习题5,其配套教参的提示解法存在问题,认为在计算过程中没有考虑大气压强的影响。我认为这一看法还有待商榷,关键是要能正确地理解锅炉内蒸气压强的含义。
Some teachers pointed out that the People’s Education Press junior middle school physics textbooks first volume p. 163 Problem 5, there is a problem with the solution to the suggested teachings, and it is considered that the effect of atmospheric pressure is not considered in the calculation process. I think this view is yet to be discussed. The key is to understand the meaning of the steam pressure inside the boiler correctly.
