点变异 meaning in English

point variogram

( 5 ) ga ' s operators are improved to reach better evolution effects , such as choosing proper fitness function , using 2d equal - block crossover and multi - bit mutation , expending the population size to reach better evolution effects . the structural results are effectively made better
( 5 )本文提出了二维均匀分块交叉、 “扩大种群”的进化机制，引入多点变异，保证了ga种群适应度平均值的有效进化和群体的多样性，实现了拓扑结构的遗传进化。
Abstract : the polymorphism of angiotensinogen gene at position 174 was studied in 90 cases of essential hypertension patients and 109 controls by pcr , restriction enzyme analysis and electrophoresis methods . the results showed the distribution of genetypes in hypertension group was significantly different from that of controls group . this suggested there is a correlation between the variant of agt174 and hypertension
摘要本文采用pcr 、限制性酶切和电泳分型等方法,分别对90例原发性高血压患者和109例正常人血管紧张素原基因多态位点agt174进行了检测,结果表明,高血压组中三种基因型的分布与对照组显著不同,提高该位点变异与原发性高血压的发生相关。
