row spacing

It is believed that there is an optimal row spacing and column spacing in the plane charge layout which is beneficial to thrown pilling.

平面布药结构存在一个有利于抛掷堆积的最佳间、排距。

tests carried out from 2001-2003 clarified that the factors needed for the cultivation method of rice direct sowing before flooding, such as suitable varieties, row spacing, density, sowing depth, and amount of calcium peroxide.

经过2001～2003年三年的试验研究，明确了寒地水稻折衷直播栽培的适宜品种、种植行距、密度、播深及供氧剂包衣对出苗的影响。

Effect of plant and row spacing on biomass and Brix of stem juice of sweet sorghum

不同行株距种植对甜高粱生物量和茎秆汁液锤度的影响

Through a lot of small scale simulated tests in construction field, this paper systemically analyzed the dependence of the open area and visible depth of blasting craters, the thrown distance and the accumulation state of rock on the row spacing and the column spacing of plane charge.

本文通过在施工现场进行的大量小型模拟实验，对平面药包间、排距与爆破漏斗的开口面积、可见深度、爆岩的抛掷距离和堆积形态等关系进行了系统分析与研究。
