“两部分气体”试题在高考试卷中常常出现在计算题内。该类型试题涉及的物理量多,其间关系复杂;题中隐含条件难觉查,易遗漏;需要列出的方程数量多,解题难。对这种题型生疏,解答就会出现“卡壳”现象。因此,分析解这类题所遵循的共同规律,整理出它们一致的特点是必需的。现以两道高考题加以评析。 The “two-part gas” test questions often appear in the calculation questions in the high test papers. There are many physical quantities involved in this type of questions, and the relationship between them is complex. Implicit conditions in the questions are difficult to detect and easy to omit. There are many equations that need to be listed and it is difficult to solve problems. If you are familiar with this type of question, the answer will appear to be a “clamshell” phenomenon. Therefore, it is necessary to analyze the common rules for solving such problems and sort out their consistent characteristics. Two college entrance examination questions are now to be assessed.
