摘要
本文对现行工科普通物理教材某些版本中提到的运动叠加原理,转动定律的矢量式,电位移的定义,o光与e光共面的条件,布喇格公式推导过程中的物理图象等问题进行了讨论,并提出了一些新见解。
This paper discusses the five problems, such as the movement super-position principle,etc, and puts forward in some present teach materials ofengineering general physics. The main work done by the author is follow-ing: demonstrating mathematically that the movement superposition prin-ciple is not general, pointing out that it is not scientific that the rota-tional law of the rigid body rotating around a fixed axis is described asM=,clarifying that it is not appropriate that the electricdispricement vector in any medium is defined as D=εE, proving that thecondition of common surface of o-light and e-light in single crystal isonly that the light axis is contained in the incident surface, and, clear-ing up the ambiguous narration given in the derivation of the physicalimage of Bragg's formula for the some engineering teach materials.
