relative air density
解釋
相對空氣密度-
The same period, the ocean thermal slow, relatively high temperature, air density changes smaller solipsism relative area of low pressure
同一時期，海洋散熱較慢，溫度相對地較高，空氣密度變化較小，遂形成相對的低壓區。 -
The relative air density decreases with the increasing of altitude. therefore, the discharge performance of air - gap and insulator string at high altitude regions is different from that of the referring standard conditions
高海拔地區相對空氣密度較低，絕緣子和空氣間隙的放電特性與低海拔地區有很大的差異。 -
Only when it takes humidity ratio h / ? as independent variable instead of absolute humidity h in researching and calculating the influence degree of the humidity on the discharge voltage, the emendation coefficients of relative air density and humidity can be independence, and can reflect the influence degree of atmospheric parameters on outer insulation discharge voltage actually
當以比濕h代替絕對濕度h為自變量研究和計算濕度對放電電壓的影響程度時，相對空氣密度校正系數和濕度校正系數才能相互獨立，才能真實地反映大氣參數對電氣設備外絕緣放電電壓的影響程度。 -
In the course of the computation, the basic parameters of the atmosphere status of the examples, such as air density profile, temperature profile, relative humidity profile, were compared and further analyzed. the results were showed by means of data forms and curves, which reflect the basic status of the actual atmosphere clearly and detailedly
在計算過程中，對各樣點的大氣狀況的基本參數，如空氣密度廓線、溫度廓線、比濕廓線進行了比較和分析，並將計算結果以數據表格和曲線的形式列出，較為清楚、詳細的反映了實時大氣的基本狀況。 -
The experimental results of air heat transfer show that the relative fin height, relative fin width, relative fin pitch and density of 3 - d ift with staggered arrangement fins all have an effect on heat transfer and flow friction. especially, the effect of fin density is bigger
空氣換熱實驗的結果表明：肋叉排三維內肋管的相對肋高、相對肋寬、相對肋間距以及肋密度均對其對流換熱特性有影響，其中肋密度的影響較大。 -
Researching and analyzing on the test results of the influence of atmospheric parameters on outer insulation discharge voltage and its various emendation methods, it can be concluded that : with the change of relative air density, its humidity ratio h / ? will also change even though the absolute vapor mass ( absolute humidity h ) of the air is constant. consequently, the influence degree of the humidity on the discharge voltage should change, too
本文通過對以往的大氣參數對外絕緣放電電壓影響的試驗成果及各種校正方法的研究分析認為：隨著相對空氣密度的變化，即使空氣中所含水氣的絕對質量（絕對濕度h ）保持恆定，其比濕h也會變化，必然地，濕度對放電電壓的影響程度也會變化。 -
In order to accurately measure the relative density of pitch mix biggest theory, to set the factors of affecting volume of air voids ( vv ) in comparatively small range, the paper analyzed the disadvantages of several standard biggest theories relative density messurement methods for pitch mix materials on their value, and put forward the operation of applying pitch dippimg method to measure biggest theory relative density for pitch mix
摘要為了準確測定瀝青混合料最大理論相對密度大小，將影響空隙率值的因素控制在較小范圍內，分析了規范中幾種不同的瀝青混合料最大理論相對密度測定方法不足對其值的影響，提出了用瀝青浸漬法測定瀝青混合料最大理論相對密度的操作方法。 -
The change of atmospheric pressure reflect the change of the altitude and the change of the temperature 、 humidity and relative air density in the different altitude region, so the atmospheric pressure is able to be use for the characteristic parameter of token the effect of the altitude on external
氣壓可作為表徵海拔高度對外絕緣放電電壓影響的特徵參數；高海拔地區空氣間隙和絕緣子串的放電電壓u均可表示為相應海拔下氣壓的冪函數，即u = u0 （ p / p0 ） n ，其中氣壓對放電電壓影響的特徵指數n與電壓類型和放電間隙的結構類型以及絕緣子類型等有關。
