| 1. | Pressure differences are indicated on weather maps by isobars .
在气象图上气压差用等压线表示。 |
| 2. | A region of low pressure with roughly concentric isobars is known technically as a cyclone .
具有大致同心的等压线的低压区在技术上称为气旋。 |
| 3. | Isobars can also be used to deduce wind conditions
等压线也可用来推断风的情况。 |
| 4. | Isobars can also be used to deduce wind conditions
等压线也可用来推断风的情况。 |
| 5. | Isobars are usually drawn at 2 or 4 hpa intervals
等压线一般以2或4百帕斯卡分隔。 |
| 6. | Isobars are useful in revealing the surface pressure pattern
等压线能有效地显示地面气压的分布状况。 |
| 7. | What is an isobar
什么是等压线？ |
| 8. | Measurement of these nuclei are often limited by interferences of isotopes and isobars
在测量这些核素时，通常存在同位素和同量异位素的干扰。 |
| 9. | The atmosphere pressure gradient is an inverse measure of the spacing of the isobars on a weather map
气压梯度与天气图上等压线的间隔大小成反比。 |
| 10. | Near the earth s surface , however , friction tends to cause the air to move slightly inward across the isobars
接近地球表面，摩擦力使空气稍微向内越过等压线。 |
