controlled wind speed 中文意思是什麼
controlled wind speed
解釋
控制風速-
It shows that the injection quantity and the difference of temperature distribute as a parabola which is at the same load, and the minimum of the parabola corresponds to the optimum quantity of injection ( g ). under the condition that the quantity of injected mass, the air speed and the heat quantity is respectively g, v and q, the research demonstrates that the pentium iv chip ' s temperature variation can be controlled under 40c and work normally when the wind speed overpass 1. 5m / s and the power dissipation of the chip is 60w. otherwise this paper calculates the flooding limit of thermosiphon with several different methods
對其充灌量、散熱量、電子元件（ cpu模擬晶元）表面與環境溫度之差及通風、流速的影響進行了系統的測試，發現充液量與溫差的關系在負荷不變時呈拋物線分佈，其極小值點對應的充液量是最佳充液量g 。在充液量為g時，對風速v 、散熱量q進行的研究表明，當風速超過1 . 5m / s后，奔騰晶元在60w發熱條件下晶元溫度小於40 ，能滿足長期正常工作。 -
The results indicate that the evaporation of naphtha is notably influenced by wind speed and evaporation area when the wind speed is low and evaporation area is small, influence becomes weak with the increase of wind speed and evaporation area, which shows the evaporation process for naphtha is controlled by boundary layer evaporation at some degree
實驗結果表明，石腦油在低風速和液面面積較小的情況下，石腦油的蒸發受風速和液面面積的影響明顯，增加風速或增大液面面積后，影響減弱。 -
Based on research of wind turbine aerodynamic characteristics, this paper analyzed various control methods for a pitch - controlled system of variable - speed and constant - frequency wind turbine at a wind velocity range higher or lower its speed rating respectively
摘要在風力機空氣動力學特性分析的基礎上，討論了變速恆頻風力機組變槳距機構在低於額定風速階段和高於額定風速階段的不同控制策略。 -
They will short down the working life of air compressor because they are always started or stopped when we want to make the railway carriage stay in a fixed temperature. now, automatic and intelligent control systems are being applying in bus air - conditions control. in this way, computers control the work of air compressor, the turnaround speed of fan, the open degrees of wind controlled doors and so on
我國大多數客車空調仍然採用簡單的壓縮機開關控制及循環離合控制系統，如：離合器?熱力膨脹閥系統（ cctxv ）和離合器?節流管系統（ ccot ） ，這些控制方式的精度低，當進行恆溫控制時壓縮機處于頻繁的開、停狀態，縮短了壓縮機的工作壽命。 -
Thought the pan evaporation, it has been found that the evaporation of shengli crude oil is controlled by the first step and the effect of wind velocity is small. the prediction equation is dw / dt ^ k d ? 2 a ju, y hct / t, which is related with the liquid characters and states ( e. g. thickness, area, viscosity ) and is independent of wind speed
2 、實驗結果表明，勝利原油蒸發由第一步即蒸發由液體內部易揮發組分向液體表面的遷移來控制，因此風速影響很小，建立速率方程時不必考慮風速，只需考慮液體本身的性質和狀態（如厚度、表面積、粘度等） ，速率方程可寫為： dw dt = kd4 ? 』 a嚴t 。 -
