low ridge meaning in English
低垄
Examples
- Long low ridges which rise above the marsh form the only inhabitable areas on the plain .
隆起在沼泽上的一系列又长又矮的山脊，是平原上唯一可以栖住的地方。 - Research on peculiarity of wave in the downstream of diffluent piers with low ridge
低坎分流墩消能工下游水流波动特性研究 - Along with several other ancient monuments , it stands on a low ridge over - looking the boyne valley , a place famed in myth and legend
它与其它几座古代墓碑一样，矗立在一座低矮的山脊之上，俯瞰着一个以神话传说而闻名的地区? ?波恩河谷。 - What ' s more , we put forward some experienced formulas on the basis of the cortical analysis . the result of the research show that by installing diffluent piers with low ridge , we can eliminate the root of oscillatiny water jump , perfect the energy dissipation effect of water jump , also , we can improve the flow condition of down - stream . the fact that the main flow of down - stream is in the middle , not only effectively lower the speed of the bottom flow in the ridge rear , alleviate the erosion to the river bed , but also avoid the heavy wave resulted from the main flow in the surface , thus improve the surface wave of down - stream obviously . we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas , and then reckon the down - stream surface wave condition for the protected building of the down - stream bank
研究结果表明：设置低坎分流墩后，消除了摆动水跃水舌摆动的根源，提高了水跃的消能效果，改善了下游水流流态。下游水体的主流在中部，既有效的降低了坎后水流底流速，减轻水流对河床的冲刷，又避免了主流位于表面导致波浪过大的结果，下游的水面波浪明显得到削减。依据经验公式，可根据工程水流条件设计出低坎分流墩的体型参数，进而估算出下游沿程的水面波浪，为下游岸边的砌护提供依据。 - Current . in order to make diffluent piers with low ridge to be popularized and applied , the surface wave of low fr . current is chosen as the research object . we measure the surface wave elements and the velocity distribution of various diffluent piers scheme by the experiment of physical model . we also analyze the average wave height , the the average value of the square of wave , unit width of the wave ' s energy , the probability density distribution of wave height , and the power chart character , so as to reveal the weakening wave mechanism of the diffluent piers
低fr水流的核心是波浪问题，为了低坎分流墩的推广应用，本研究以低fr水流的表面波浪作为研究对象，通过物理模型试验，对各种分流墩方案消能工的下游水面波浪要素、流速分布进行测试，分析低坎分流墩下游波浪的平均波高、均方根、单宽波能、波高概率密度分布及功率谱特性变化规律，从而揭示了低坎分流墩的削波机理。
