| 工业生产过程中排放的温室气体会造成全球变暖现象,但全球变暖与工业排放在时间上具有一定的滞后效应.通过分析地球、大气、太阳三者热平衡体系的辐射换热,建立了地球及其大气的动态数学模型;利用此模型考察了造成地球温度变化的主要原因和变暖滞后的现象.结果表明:工业温室气体的过度排放会造成大气对地球辐射的吸收系数提高,导致地球温度升高;同时,太阳辐射能量增加,地球和大气对太阳辐射吸收增加,导致地球温度升高.结合近年来人为因素造成的地球温度升高现象进行了定量热分析,预测了温室气体CO2体积分数线性增加条件下的地球温度走势. |

| The greenhouse gases generated by industrial production processes can result in the global warming.However, compared with the discharge of industrial waste gases, the global warming has a certain lag on time.Through an analysis of radiative heat transfer in the heat balance system of the earth, the atmosphere and the sun, a dynamic, mathematical model was established in this paper.The main reasons of changes in the earth’s temperature and the hysteresis of global warming were analyzed by this model.The results showed that an excessive discharge of industrial greenhouse gases can increase the atmospheric absorption of earth’s radiation and lead to an increase in the earth’s temperature.At the same time, the increase of solar radiation energy can raise the absorption of the earth and the atmosphere to the solar radiation and makes the earth temperature to rise.A quantitative analysis of the earth’s temperature rising phenomenon caused by human factors in recent years was carried out and the earth temperature change trend was predicted under the condition of a linear increase in the volume fraction of greenhouse gase CO2 |
