一、叠加原理当一个系统受到某种作用时,就会有对应的响应.当几个作用同时作用系统的效果等效于单个作用分别作用于系统的和效果时,我们就说作用满足叠加原理,这个系统也称为线性系统.叠加原理在电磁学、电动力学中应用极其广泛,它是物理学的基本原理之一.如果物理量是标量,我们可以把数值直接相加减;而如果是矢量就要符合平行四边形法则.叠加原理在矢量的运算、合成以及公式推导方面应用显著,例如电场强度、
First, the principle of superposition When a system is subject to a certain role, there will be a corresponding response.When several roles at the same time the effect of the system is equivalent to a single role in the system and the effect, respectively, we say that the role of superposition principle , This system is also called linear system.The superposition principle is widely used in electromagnetism and electrodynamics and it is one of the basic principles of physics.If the physical quantity is a scalar we can add and subtract the values directly.When the vector It is necessary to comply with the law of parallelogram.The principle of superposition in vector computing, synthesis and formula derivation aspects of the application of significant, such as electric field strength,
