摘要: 通过探测地球整体的辐射温度变化,即在空间把地球作为一个辐射点源对待,同时又将地球分成几百个局部,视为一个面源,进行实时的比较;又分别对太阳和宇宙背景的辐射温度变化进行测量,来了解地球表面和地气的热温度状况和太阳对地球、对宇宙背景能量传输的情况。从而研究地球上大规模灾害性事件(包括火山的爆发、地震、大气环流、气候变异等…)在整个地球上所能反映的热温度效应。探测地球在宇宙空间非平衡热状况下(太阳温度6000K;地球温度300K;空间背景3K)的耗散结构,研究在这种状况下物理力学的一些自会聚和自组织现象(即地球上灾害性事件形成过程),形成一门非平衡宇宙热力学,并使之成为一门实验科学。文章着重介绍为此目的实施的探测方法和其应用前景。

Abstract: The purpose of this paper is to compare practically the dif-ferences of radiation temperatures between two methods,one is by recordingthe thermal status of the Earth and its atmosphere as a whole by a radia-tive spot source,and the other is by considering the Earth as a surfacesource by dividing it into several hundreds belts.We measure the tempe-rature changes of the sun and the cosmic environment respectively to get the knowledge of the thermal status of the Earth surface and its atmos-phere and also get the information about energy transpotation from the sunto the Earth or the cosmic space,thus we could study the thermal effectsreflected on the Earth by large scale terrestrial catastrophic events,such asvolcanic eruptions,earthquake calamities,climatic changes etc.,We detectthe dissipative structure of the Earth in space under the non-balancingthermal conditions(in the solar system,the solar temperature is 6000K;on the Earth the temperature is 300K and the temperature of the spacebackground is 3K)and study the auto-collected and auto-organizedphenomena under this status of physical mechanics events(the generationprocess of catastrophic events on the Earth),therefore we can establisha new branch of learning which is called non-balanced space thermody-namics and make it as an experiment science.The emphasis of this paperis to introduce the detecting methods used for above purposes and thefuture prospect of application.
