relative air density meaning in English
相对空气密度
Examples
- 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
高海拔地区相对空气密度较低，绝缘子和空气间隙的放电特性与低海拔地区有很大的差异。 - 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
当以比湿h代替绝对湿度h为自变量研究和计算湿度对放电电压的影响程度时，相对空气密度校正系数和湿度校正系数才能相互独立，才能真实地反映大气参数对电气设备外绝缘放电电压的影响程度。 - 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
本文通过对以往的大气参数对外绝缘放电电压影响的试验成果及各种校正方法的研究分析认为：随着相对空气密度的变化，即使空气中所含水气的绝对质量(绝对湿度h )保持恒定，其比湿h也会变化，必然地，湿度对放电电压的影响程度也会变化。 - 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
气压可作为表征海拔高度对外绝缘放电电压影响的特征参数；高海拔地区空气间隙和绝缘子串的放电电压u均可表示为相应海拔下气压的幂函数，即u = u0 ( p / p0 ) n ，其中气压对放电电压影响的特征指数n与电压类型和放电间隙的结构类型以及绝缘子类型等有关。
