“重核的裂变与轻核的聚变”是高二物理“原子和原子核”一章的内容 .由于课本在此前一节“核能”中已经介绍了爱因斯坦的质能方程 ,并进行了相关的练习 ,所以“重核的裂变与轻核的聚变”实际上是在学生掌握了原子核组成和质能方程的基础上 ,进一步探讨原子核的能量问题 .课本 “Heavy nuclear fission and fusion of light cores” is the content of the chapter “Physics atomic and atomic nucleus” in the second year of Physics. As the textbook has already introduced the energy equation of Einstein in the previous section “Nuclear energy”, and related Practice, so “heavy nuclear fission and fusion of light core” is actually based on the students’ understanding of the composition of the atomic nucleus and the energy equation, and further explore the energy of the nucleus.
