If the law of parity conservation were suspended, this restriction would be removed. 如果宇称守恒定律受到破坏,就会取消这个限制。
Combining the previous data, the conservation and variation of mtDNA restriction sites of mammals among far ranged species were also discussed. 结合以往积累的资料,我们对哺乳动物mtDNA限制性位点在远缘物种间的保守性和变异性进行了初步讨论。
According to different geomorphic units of the basin, the different patterns of groundwater exploitation and utilization and the conservation areas are established by dividing the basin into restriction area, storing area, controlling area and the prohibition area. 根据流域的不同地貌单元,制定出不同的地下水开发利用模式与保护区,按照限制开采、调蓄开采、调控开采和禁止开采等四个区域确定地下水利用模式。
