【摘要】 本文讨论了物理模型的建立和使用中的几个值得注意的问题。指出:物理模型的建立必须有一定客观基础与实际可能;对于同一客体可根据研究内容不同而选用不同的模型;由某种物理模型得出的物理定律的适用条件不可超出相应物理模型的使用范围。更多还原

【Abstract】 This article analyzes the foundation and application of physics models. A physics model must have its objective basis and its real possibility. To one subject,we can choose different models according to different research aspects. The fitting condi- tons of the physics laws that come from physics models should not be beyond the physics models’using range更多还原
