| 1. | The air pressure is determined by the height of mercury column 利用水银柱的高度来量度气压 |
| 2. | He found that the mercury column measured the predicted height 他发现水银柱达到了预期的高度。 |
| 3. | Vertical mercury column nanometer 立式汞柱血压计 |
| 4. | The height of the mercury column ab will vary according to the air pressure 水银柱ab之间的高度会随气压而改变。 |
| 5. | The height of the mercury column ab will vary according to the air pressure 水银柱ab之间的高度会随气压而改变。 |
| 6. | The higher the air pressure , the greater will be the height of the mercury column 气压愈大,水银柱的高度亦会愈高。 |
| 7. | The higher the air pressure , the greater will be the height of the mercury column 气压愈大,水银柱的高度亦会愈高。 |
| 8. | The vapor pressure above the mercury column and the specific weight of the mercury change 48为什麽气压计的压力读数,与温度有关 |
