【摘要】 观察了大豆10个没种处理结英株数的差异，将其作为协变量对各处理籽粒干重的数据进行了分析，首创用字母加名次的双重标记法表述多重比较结果，以便更精确地反映统计控制的效果。就不同的试验指标阐明了实施统计控制必须具备的先决条件，更多还原

【Abstract】 Ohservations were made on quantitative differences of pods bome by soybeans whose seeds had been soaked in 10 different treatments. these data being concomitant varialbes, the yieldof each plot are analysed in the paper, The mode of double markings with alphabet and place-order for the result of multiple comparisons reflects exactly the effects of statistical control.
