The higher the precipitation, the greater the root depth, total root length and root diameter, the more lateral roots and the lower ratio of root to shoot.
降雨量越大,根系越深、总根长越大、根系直径越大、侧根越多、根冠比越低。
2
It does not require irrotational conditions and the limitation of the ratio of wave length to water depth.
它没有无旋条件,没有波高对水深比值的限制。
3
Some influence of the ratio of length to diameter of SCESHL on the velocities of jetting penetrator were observed but appeared mildly on the penetration depth into water.
