摘要
为解决在工业,农业试验中,很多实验常常需要一定时间才能完成,这时的试验结果易受时间趋势干扰的问题,借助趋势无关设计的若干等价条件,利用平方幻方的特有性质,给出了一类2阶趋势无关设计的简单构造方法。
Lots of experiments have taken for a period of time.Based on the equivalent conditions and special properties of bimagic squares,this paper discussed the bimagic squares in experiment of design,which shows that the two factors are 2-trend free.
