角粒沙 的英文怎麼說
中文拼音 [jiǎolìshā]
角粒沙
英文
angular sand-
Whether sand can saltate from sand bed surface and quality of sand incipience are very important to the sand transport and the form of wind - blown - sand
沙粒能否起動以及起動質量如何，如起動初速度、起動角度等參數都直接關繫到沙粒的輸運和風沙兩相流形成。The quality of sand incipience involved with many kinds of parameters, such as incipient velocity, incipient angle etc. our research depends on the advantage of cross - knowledge and makes a research on this subject by gas - solid hydromechanics theory and ptv measure technology
本論文發揮交叉學科的優勢，採用氣固兩相流體力學理論和ptv測量技術研究這一現象，從新的角度認識沙粒起動和風沙流結構，為風沙流動的研究打開了新的思路。The shape of model sand particle play an important role in submarine rest angle, starting speed, bulk specific weight and some other physical characters
摘要顆粒形貌對模型沙的水下休止角，起動流速、堆積密度等性能有顯著影響。4. the non - linear interaction mechanism derived from the scale of system was discussed. the paper deemed that, falling sliding face is not a rectilinear type, the non - linear coupling of falling factors sharply enhanced in large sand - pile ; the stabilization of surface layer sands are different in the time and space, especially the stating probability is higher than halting, and probability of fault in slope foot is higher than top as well ; the faulting forms will be affected by bounder situation strongly
大尺度散粒體坡面的崩塌滑動面，一般並非直線形，在崩塌過程中的耦合作用將增大落沙規模；理想化的沿直線坡面滑動情況，坡面表層砂粒的穩定性也並不是在時間、空間上都均衡的，可以造成起動容易止動難，或坡角失穩概率大從而牽連整個坡面的情況；長大高陡坡面的失穩形式，可以受坡腳（邊界）的巨大影響。分享友人
