- wind sand flow 风沙运动
- Can sand flow upward in the hourglass? 时光会倒流吗
- The airflow and the sand flow were taken as continuous flow bod y for study object in mathematical pattern. 在数学模型中，把气体和砂粒作为研究对象，并且将它们都看作连续的流体。
- Sap flow flux was influenced by sapwood area size, and decreased progressively from the base along the trunk to the top of tree. 不同树干高度液流通量的变化受边材面积大小的影响，自基部沿树干高度递减；
- Looking up from under the Shapotou, who took the sand flow, "Fei Liu thousand feet down," such as from heaven. 从沙坡头下仰望，人乘沙流“飞流直下三千尺”，如从天降。
- Only the whir of the wind sand and gravel up the side of the road, the temperature drop dramatically, to fight in the face when it will realize that winter came. 只有风在呼呼的刮着，卷起路边的沙石，温度下降的厉害，打在脸上生疼，这时就会意识到，冬来了。
- The axial dispersion in chromatography models was discussed with vector method and the effect of diffusion on the bulk flow flux with its partial quantity form was pointed too. 用矢量方法讨论了色谱模型中的轴向扩散项，指出轴向扩散项是扩散通量以分量的形式在主体流动通量上的页献。
- To overcome it, a developed technology was to inject artificial gravels into oil formation to make the gravel screen to prevent sand flow. 为此研制出地层深部充填防砂技术,该技术是向油层中注入人工砾石,由其所形成的砾石屏蔽来阻挡地层出砂。
- Several mud and sand flow accidents occurred from the goaf to mining face,which had seriously affect to the mine safety production. 梅河四井为急倾斜特厚煤层,采用水平分层综合机械化放顶煤开采,曾经多次发生采空区泥砂流溃入工作面事故,严重影响了安全生产。
- Sand flow of water and sand as the proportion of different trajectories and the flow of sand from the line, could accelerate the occurrence of cavitation. 含砂水流由于水与砂的比重不同，砂粒运动轨迹与流线脱离，可能会加速汽蚀的发生。
- Yongding River sand land is the largest area of wind-sand land sand and is one of the most severe wind sand damage region in Beijing,Which has important influence to eco-entironment in Beijng. 永定河沙地是北京市面积最大的风沙化土地和风沙危害最严重的地区之一，对北京市的生态环境有重要影响。
- The model is used to study the effects of system pressure,flow flux,inlet subcolling,inlet/outlet(restriction),gap size and the ratio of do/di and the ratio of qi/qo on system behavior. 此模型被用于系统压力、质量流速、进口过冷度、进、出口节流和间隙、不同内、外径之比和内、外管的加热比对不稳定性影响的研究。
- Then the equations for velocity distribution along vertical direction of the dry sand flow and that for velocity of sand mass sliding along the subface and top surface are derived. 将干砂流视为连续介质的流动,对干砂流的运动动力和阻力进行了深入研究,建立了干砂流垂线流速分布方程和干砂流体底面、表面滑动速度方程。
- The Problem of Wind Sand Storm and Its Treatment 沙尘暴及其治理
- air-condensator model and air flow flux model，etc. 空气冷却器模型以及空气流量模型等。
- The wind was whispering in the trees. 一阵风穿过树林沙沙作响。
- The wind whirled the dead leaves about. 风吹得枯叶在四处回旋。
- The boat heeled over in a strong wind. 船在强风吹袭下倾侧了。
- The shutters thumped the wall in the wind. 在风中百叶窗砰砰地碰在墙上。
- Oh, give me a land where the bright diamond sand Flows leisurely down the stream; Where the graceful white swan goes gliding along Like a maid in a heavenly dream. 哦,给我一片地,钻石金沙顺流走;雪白天鹅水中嬉,可是仙女下凡舞?
