非线性物理模型的线性化

On Linearization of Nonlinear physics Model

自然界中并不存在真正的线性系统,而所谓的线性系统,也只是在一定的条件范围内保证其线性关系。实际上,所有的自然界系统在不同程度上,均具有非线性的性质。非线性数学模型的线性化是物理学研究自然界、描述自然界的重要方法之一,也是物理科学研究和物理教学中的重要内容。

There is no eal linear system in the nature, and so called linear system only has some linear relation under some conditins. In reality, All the natural systems have the property of nonlinearity to a certain extent, the linearization of nature could be studied and described in physics, as well as the important contents of research and teaching in physics.
