高中物理甲种本第三册在“平均结合能”的一节中,有这样的叙述:“平均结合能越大,原子核就越难拆,……平均结合能的大小能够反映核的稳定程度。”在其他物理书刊中,也常常有把结合能作为衡量原子核稳定程度的提法,如“结合能愈大,原子核愈稳定”、“平均结合能的大小是原子核稳定性的标志”。但是,这种提法未必妥当。从平均结合能越大原子核越难拆开这个角度去理解,原子核的稳定性确与结合能有关,大体上,中等质量 High school physics A. In the section “Average binding energy” in the third volume of this book, there is a narrative: “The greater the average binding energy, the harder it is to disassemble the nucleus.... The average binding energy size can reflect the stability of the nucleus. “In other physical publications, there is often a reference to the binding energy as a measure of the stability of the atomic nuclei, such as ”the greater the binding energy, the more stable the atomic nuclei“ and ”the average size of the binding energy is a sign of atomic nuclide stability." However, this reference may not be proper. From the point of view that the greater the average binding energy is, the more difficult it is to disassemble the atomic nuclei, the stability of the nuclei is related to the binding energy. In general, the medium quality
