draft coefficient 解釋
吃水系數
  • draft : n 1 選拔隊，別動隊，分遣隊；（分遣隊的）選拔；〈美國〉徵兵；（不經某人同意而要他出來競選的）敦請...
  • coefficient : adj. 共同作用的。n. 1. 共同作用；協同因素。2. 【數，物】系數，率；程度。
  1. Thirdly, the correlative coefficient is computed between the pressure fluctuation signal of draft tube and the displacement signal of upper guide bearing, the thrust bearing and the head cover, with this the conclusions on the shafts response due to pressure surge in

    並與模型尾水管壓力脈動試驗結果進行對比?結合流動模擬試驗以及動力特性計算結果，全面分析?評定機組的實際運行狀況，劃定運行區域，為電站合理調度
  2. The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull

    本文的研究分為二個部分：首先利用frank源匯法計算水動力系數，計算包括不同吃水時的附加質量和阻尼系數，吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水；然後建立和求解船舶大幅度運動方程，在實際計算時一方面考慮了運動模態之間的耦合，另一方面在計算水動力時，考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動力系數隨吃水瞬時變化，靜浮力的計算精確到船體瞬時濕表面積，最後用四階龍格?庫塔方法在時域內求解船舶運動方程，並進行了載荷計算。
  3. Based on the analysis and calculation of ship resistance, according to the main factors influencing the resistance, such as sailing speed, water depth and ship draft ratio, and coefficient of sectional form, the deepwater, shallow water and restricted channel are defined by the coefficient factor

    摘要通過對船舶阻力的分析和計算，根據影響阻力的主要因素，航速、水深與船吃水比、斷面系數，由換算系數來界定深水、淺水與限制性航道。
  4. ( 5 ) the synthetic draft curve was conducted by crop coefficient and relative soil moisture. the correlation in crop coefficient and relative water content takes on uniform trend comparing to the soil water deficient degree. in the whole growth season of cotton, the high correlation coefficient occurred in the period of seeding, which was declined in the period of blooming and flowering, whereas it was raised in the late period of cotton

    （ 5 ）綜合作物系數與相對含水率擬合關系表明，作物系數與含水率的相關性與土壤受旱的情況呈現相同的趨勢，苗期的相關系數高，而到了蕾期偏低，花鈴期更低，到了吐絮期有所升高，整體上表現為水分狀況良好，相關性就越高。
