river round meaning in English
河牌圈
Examples
- The lateral erosion velocity of bahe river round lantian accelerates , this may be resulted from the accelerating uplift velocity of lishan mountain
蓝田段灞河的侧蚀速率逐渐增大，这可能与骊山掀斜式隆升速率增大有密切联系。 - Their downcuting velocity accelerates except luohe river round luochuan . the erosion velocity of weihe river round tianshui and jinghe river round binxian reduced , and the lateral erosion velocity of luohe river round luochuan reduced . this may be due to the reduced flow
天水渭南镇段渭河、彬县段泾河的侵蚀速率呈脉动式减小，秦家河段洛河侧蚀速率逐渐减小，这可能与河水流量随时间推移逐渐减小有关。 - This theme selected weihe river round tianshui , jinhe river round binxian , bahe river round lantian and luohe river round luochuan to study the evolutionary model of river terraces in the mid - tail of weihe river . we have built the cross - section of each river , and analyzed the evolution of each river terrace in the mid - tail of weihe river according to the velocity of downcuting and lateral erosion
本论文以天水渭南镇段渭河、彬县段泾河、蓝田段灞河和秦家河段洛河为例建立渭河中下游河流阶地演化模式，以阶地形成年代为标尺，根据下切速度和侧蚀速度对渭河中下游各河谷阶地的演化过程进行了分析。
