負定向角
英文
negatively oriented angel-
Second, this paper analyzes the relation of reactive support service with voltage, power limit curve, transaction amounts. according to the power limit curve, this paper analyzes the source of the reactive cost to get an interzone cost function. using marginal cost theory, it concludes that the reactive spot price is the derivative of the cost function in generator buses
另外，本文還從發電機角度上分析了無功服務與電壓、功率限制曲線、發電機向負荷傳輸電能大小的關系；根據功率限制曲線對發電機無功成本的來源進行詳盡剖析，從理論上確定一個分區間的成本函數；並依據短期邊際成本理論可推出，計算發電機節點的電價可採用無功成本函數的偏導數的方法。Maintaining a forward ground - sole contact point improves directional control and ball flight by reducing the potential of the club to bounce or skip into the ball - especially from closely mown fairways, for players who play the ball forward in their stance or for players who sweep the ball from the turf with a shallow attack angle
藉由降低擊球路徑的潛在負面因素，維持穩定的觸地點能改善方向控制與飛行路徑-尤其是在短草球道上想擊出漂亮直球的球友，或是得利用較淺的擊球角度自長草區擊出的情況下。The power angle characteristics are acquired and compared with the unsaturated curves. it is concluded that the stability limit of the power angle is less than 90 degree. reactive power regulating curves are calculated and compared with those curves when saturation effect is not considered, the result is that u type curves are deviated to the right
通過對同步發電機各種運行曲線的計算，在已有文獻的基礎上更進一步分析了鐵磁材料飽和以及磁場畸變對同步發電機運行特性和參數的影響；求出了空載特性曲線和零功率負載特性曲線，在不同的電樞電流下計算得到的波梯電抗不同；求出了功角特性曲線，與不計飽和時的功角特性曲線相比較，功角穩定極限小於90 ；求出無功調節曲線，與不計飽和時相比較， u型曲線向右偏移。Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum
研究結果表明：傾斜角度一定，當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時，流體速度和熱質傳遞速度從高逐漸變低並出現最小值，此後隨著向下浮力的增大，流體向下流動且隨| b |的增大而加速，熱質傳遞速率隨| b |的增大而重新增大。A new special panel, comprising members of the economic and trade commission of the guangdong province ; the environment, transport and works bureau of the hksarg and relevant departments of the two governments, will be set up under the jwg. the new panel will be responsible for promoting public education and technology of the energy saving measures and clean production amongst the commercial and industrial sector in the prd region
在會議上，雙方決定在合作小組轄下成立一個新的專題小組，由廣東省經濟貿易委員會和香港的環境運輸及工務局以及兩地的相關部門組成，負責向珠江三角洲地區工商業推動節能和清潔生產的教育和技術。In view of the importance of such partnerships, the hong kong health sector will take a leading role in facilitating the government, non - governmental organizations and business sectors in addressing the determinants of health through an integrated policy approach
有鑒于這種伴關系的重要性，本港衛生界將擔綱領導地位，在政府、非政府及私營界別之間負起協作角色，以一套綜合性的政策方向來處理各種影響健康的決定因素。分享友人
