  3. 对称能是核力的同位旋依赖性的体现，对称能的存在与大小必然受到核环境的影响。对称能是核力的同位旋依赖性的体现，对称能的存在与大小必然受到核环境的影响。 对称能具有较强的密度依赖性，较弱的温度依赖性。 在对对称能的密度依赖的理论研究中，人们发现，不同理论，甚至相同理论的不同参数组给出极大的不确定度。 这种不确定度在高密区更为明显，研究的难度更大。 Why? ---Basic statement Semi-empirical mass formula : +  Liu B. et al., PHYSICAL REVIEW C 2002, VOLUME 65, 045201 QF 4 "Topical Workshop on NSEA"
