The research deals with the correlations between the parameter of repetitive degrees and each factor of different subjects, distances and seasons in repetitive training for sprinting.
通过实验研究、数理统计、比较分析等方法，对重复训练法在短距离跑训练中不同专项、距离、季节与重复次数指标相关性进行实验研究。
The results show that the correlations between the trial errors are depended on different soil layers and time periods. The correlations are increased with narrow spatial and temporal distances.
结果表明，该类试验的误差在不同深度土层间和时段间存在相关性和异质性，其相关性随着土层间距和时段间距减小而增大。
