And based on the similar symmetry reduction,it proves that similar symmetry structure may make half of its structure as research subject for calculation just as axis symmetry structure.
提出了相似对称性和相似对称结构等概念,通过相似对称性在相似对称结构上的应用,揭示了相似对称结构的内力和变形的相似对称性规律,由相似对称性规律进一步发现相似对称结构和轴对称结构一样也可以取半边结构,使计算简化。
Absolute rights and absolute legal relationships are generally accepted by jurists,but as of no literature on the absolute legal act or relative legal act appears.
法学界普遍承认绝对权和绝对法律关系存在的客观性,但目前还没有见到任何关于绝对法律行为和相对法律行为的论述。
