| 1. | The drag force decreases as the air density decreases .
当空气密度减小时阻力也减小。 |
| 2. | 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。 |
| 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. | 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。 |
| 6. | Everything else being equal , a cold air column , because of its higher air density , is heavier than a warm air column and thus produces a higher air pressure
在一般相同情况下，冷空气柱因其密度较高，会比暖空气柱重，因而产生气压较大 |
| 7. | Everything else being equal , a cold air column , because of its higher air density , is heavier than a warm air column and thus produces a higher air pressure
在一般相同情况下，冷空气柱因其密度较高，会比暖空气柱重，因而产生气压较大 |
| 8. | 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。 |
| 9. | For " upper - air " , weather maps are usually drawn for isobaric ( i . e . equal pressure ) surfaces following the practice of conventional upper - air observations and analysis . air density and atmospheric pressure generally decrease as altitude increases
至于高空方面，由于常规的高空观测与大气分析都是在标准等气压面上进行，所以高空天气图亦习惯在等压面上绘制。 |
| 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。 |
