人教版高中《物理》(选修3-3)第80面第1题有关组合问题的分析及其《教师教学用书》给出的参考解答是错误的.下面笔者针对该题给出正确的分析与解答.原题一锅开水投入5个糖馅的甜汤圆,随后又投入5个肉馅的咸汤圆,甜、咸汤圆在沸水中翻滚,象征着封闭系统一个自发的过程.随后,两只碗各盛了5个汤圆,每碗汤圆中共有六种可能:①全是甜的.②全是咸的,③1甜4咸,④4甜1咸,这是四种不平衡的宏观态;⑤2甜3咸,⑥3甜2咸,这是两种相对平衡的宏观态.两只碗各盛5个汤圆共有32种组合方式,我们称为32个微观态.试问:(1)以上六种宏观态所对应的微观态个数各是多少?请设计一个柱状图表示.(2)以上相对平衡的宏观态出现的概率是多少?解法一(教师教学用书中的参考解答) (1)如下表:(柱
The PEP (High School Physics) (Elective 3-3), Section 80, Problem 1 The analysis of the combination problems and the reference solutions given by the “Teaching Book for Teachers” are incorrect. The following gives a correct analysis of the problem And the solution. The original question a pot of boiling water into the five sugar filling sweet dumpling, and then put five meat salty dumpling, sweet, salty dumpling roll in boiling water, a symbol of the closed system a spontaneous process.Subsequently, two There are six bowls of rice balls in each bowl, and there are six possible bowls in each bowl: ① all sweet, ② all salty, ③ 1 sweet and 4 salty, ④ 4 sweet and 1 salty, and these are four unbalanced macroscopic states; Sweet and salty, sweet and salty, sweet and salty, sweet and salty, sweet and salty, sweet and salty, sweet and salty, sweet and salty, sweet and salty, (2) The above is the relative balance of the macro-state is the probability of what is the number? Solution a (reference for teachers in teaching books) (1) The following table :(column
