场是物质存在形态之一。物理学中除电场、磁场外,还有其他场,深刻认识场的本质,对学好物理具有十分重要的意义。曾有人认为物质的相互作用是超距作用,作用传播是不需要时间的,场仅仅是辅助概念。随着科学的发展,大量事实已证实场和实物的结构及性质有许多相似的地方,也各有其特殊性。场和实物还可以互相转化,并有密切的联系。本文将对场和实物一比较性阐述,供教学时参考。 (一) (1)场和实物都是物质,它们不依赖于人们的意识而存在着。我们虽不能直接感
The field is one of the physical forms of existence. In addition to electric fields and magnetic fields, there are other fields in physics. It is of great importance to study physics in order to understand the nature of the field profoundly. It has been argued that the interaction of matter is a superposition effect, and the propagation of the effect does not require time, and the field is merely an auxiliary concept. With the development of science, a large number of facts have confirmed that there are many similarities in the structure and nature of field and physical objects, and they also have their own particularities. Fields and physical objects can also be transformed into each other and are closely linked. This article will explain the field and the physical comparison for reference in teaching. (1) (1) Fields and objects are substances, and they do not depend on people’s consciousness. Although we cannot directly feel
