在高中《物理》(必修本 )第二册“核能”一节中 ,教科书中叙述了质量亏损和质能方程后指出 :“物体的能量增大了质量也增大 ,能量减少了质量也减少 .核子在结合成原子核时出现的质量亏损 Δm,正表明它们互相结合过程中放出了能量ΔΕ=Δm· c2 ”.对这段内容 ,相当一部分学生在 In the “Nuclear Energy” section of the second volume of “Science in Physics” (required edition) in high school, textbooks describe quality loss and energy equations and point out: “The energy of an object increases and the quality also increases, and the energy reduces the quality. The mass loss Δm that occurs when the nucleus is incorporated into the nucleus indicates that they released energy ΔΕ=Δm·c2 during the process of combining with each other. For this content, a considerable portion of students
