物理世界的正与负

POSITIVE AND NEGATIVE QUESTIONS IN PHYSICS

分析研究了物理学科中有关正负的几个比较突出的问题,论述了负温度、负熵、负能量与负质量以及“第五种力”中势能的正与负,提出了物理量取值的“正负时偶性”原理。

Several fairly prominent concepts about positive and negative questions of subjects involving in physics are discussed,including negtive temperature,negentropy,negative energy and negative mass as well as posi-tive-negtive potential energy in 'the Fifth Force'.In addition,this paper suggests' the principle of positive-negative unity of opposite' for the measurement of paramters of physics.
