1·Remarkable yield difference was found between the two experimental plots with row spacing of 30 versus 60 cm, the former giving 30% higher crop.
这两块行距为30公分和60公分的实验地中产量有显著差异，前者高出30%。
2·A comparison of yield and its components between hybrid rice and conventional rice varieties was made with different seedling quantity and row spacing at transplanting.
比较了在不同插秧量和行距配置方式下杂交稻和常规稻的产量及其构成因素。
3·The parallel milling is adopted to curved surface NC machining. The row spacing has an effect on surface roughness of workpiece.
采用平行铣削对曲面进行数控加工时，行距对工件的表面粗糙度有一定的影响。
