摘要
由于第四强度理论还存在不足之处,因此本文从分子物理学关于引力和斥力的理论出发,再结合一些实验依据,对第四强度理论进行修正,使其适应范围更广.计算表明,本修正理论在若干方面和第四强度理论结论相差不大,但是在某些方面,特别在第四强度理论无能为力的地方本理论却可以说明问题.即可将二向等值压缩和三向等值拉抻作为本修正理论的判决性实验,一俟两个判决性实验的结果符合本理论的计算,即可将本修正理论付诸使用.
As to the fourth strength theorem,there is still inadequate on application,so this paper at first starts from the theorem of molecular attraction and repulsion,then combining some experimental facts to revise the fourth strength theorem in order to make it more applicable.The calculating conclusion shows that in several points it is only a little difference from the fourth strength theorem,but in some points especially in that place where the fourth strength theorem is helpless,the revision theorem is useful.We can take tow dimension equivalent compression and three dimension equivelant tension as the criterion experiments for the revision theroem,when the results of tow criterion experiments are incordance with the calculation of the revision theorem,then it can be put to application.
