| 中文摘要: |
| 水的相变过程会出现异常辐射现象，在短波范围内其辐射强度比普朗克辐射强度强4倍左右，这与常规的热辐射不同，称为相变辐射。针对水在凝结过程中所释放的异常辐射现象做了机理性研究，并将热力学、分子理论与所发现的实验数据相结合，提出一个新的机理来解释这一现象。研究结果表明，相变辐射的产生可能与水分子氢键的形成过程相关，辐射的波长段所具有的能量值与氢键形成时所释放的能量值较为接近，且水分子密度越高相变辐射强度越强；水分子内振动能级的跃迁与相变辐射能存在很大的联系，振动能级的跃迁伴随着光子的释放，并与在其他已发表文献中所发现的相变辐射能有着较为匹配的能量值。研究结果为进一步探讨相变辐射提供了理论基础。 |

| The phase transition process of water will cause abnormal radiation phenomenon, whose radiation intensity is about four times stronger than Planck radiation in the scope of shortwave. This process is called phase transition radiation. In this paper, the mechanism of the abnormal radiation released by the water condensation has been studied. Based on thermodynamics, molecular theory, and experimental data, a new mechanism to explain this strange phenomenon was proposed. The results showed that the generation of phase transition radiation was related to the formation of hydrogen bonds in the water molecules. Meanwhile, the energy of the radiation wavelength was close to that released when the hydrogen bonds were formed. Furthermore, the higher the density of water molecules was, the stronger the intensity of phase transition radiation was. The transition of the vibrational energy level in the water molecules was closely related to the energy of phase transition radiation and was accompanied by the release of photons, which was almost identical with the values reported in the literatures. These results can provide a theoretical basis for further study of the new phenomenon of phase transition radiation. |
