| 1. | For altitudes in excess of 350, 000 feet the air density is less than 10 -7 of that at sealevel .
在高度高于350000英尺时，空气密度仅为海平面高度的107。 |
| 2. | Environmental-temperature variations contribute to uneven air pressures due to density variations of the air in the bellows .
环境温度的变化将引起波纹管内空气密度的变化，造成气体压力不稳定。 |
| 3. | Burst point air density
爆炸点空气密度 |
| 4. | For altitudes in excess of 350 , 000 feet the air density is less than 10 - 7 of that at sealevel
在高度高于350000英尺时，空气密度仅为海平面高度的10 7 。 |
| 5. | Looking at the lift formula , you can see thatlift and drag vary directly with the density of air
你只要看一看升力公式就可以了解升力和阻力与空气密度成正比。 |
| 6. | The same period , the ocean thermal slow , relatively high temperature , air density changes smaller solipsism relative area of low pressure
同一时期，海洋散热较慢，温度相对地较高，空气密度变化较小，遂形成相对的低压区。 |
| 7. | 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。 |
| 8. | This is because of unequal heating , temperatures at different places are not the same . as the warmer air expands , the density and pressure of air decrease . the surrounding cooler air flows in to fill the void and wind develops
由于不同地方受热情况不一样使空气温度有分别，较热的空气膨胀，空气密度及气压减低，周围的较凉空气就会流过去填补空缺，而形成风。 |
| 9. | This is because of unequal heating , temperatures at different places are not the same . as the warmer air expands , the density and pressure of air decrease . the surrounding cooler air flows in to fill the void and wind develops
由于不同地方受热情况不一样使空气温度有分别，较热的空气膨胀，空气密度及气压减低，周围的较凉空气就会流过去填补空缺，而形成风。 |
| 10. | 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。 |
