| 摘要: |
| 依据水面红外发射和红外遥感测温原理,采用HDG-高灵敏度红外测温仪和常规测量仪器相结合的方法,在实验室空气稳定条件下,模拟测得了水面皮层破坏-复原(重建)的热力过程和气-水温差对水面皮层复原过程的影响,获得了大量的测量数据。数据分析表明,当气-水温差从3.0℃变为11.5℃时,水面皮层破坏可导致皮温增量从气-水温差3.0℃时的0.15℃变到11.5℃时的0.45℃,并发现恢复时间与气-水温差呈负线性关系。 |

| Abstract: |
| Based on the air-water temperature difference between air temperature and water temperature under the water surface skin layer, affecting temperature variations of the Water Surface Skin Layer(WSSL) from breaking to recovering, the thermodynamic process of WSSL from breaking to recovering and effect of the air-water temperature difference on its recovering process under the air stable condition were simulated and measured in the laboratory by the HDG-highly sensitive (IR) thermometer and other routine instruments. The measured data showed that breaking of WSSL could increase water skin temperature from 0.15°C when the air-water temperature difference was at 3.0°C (air temperature is higher than water temperature) to 0.45°C at 11.5°C (air temperature is also higher than water temperature). At the same time, the negatively linear relationship between the recovering time of the water skin temperature and the air-water temperature difference is identified. |
