地球上的万物无不沐浴着太阳的光辉,生生息息,不断发展、进化。随着科学技术的进步,太阳奥秘不断被揭示,太阳辐射能的利用提上了日程。 太阳这个星体是如何向外辐射能量的呢? 首先,太阳是一个高温星体。现代物理研究的一种假说认为,在星体形成之前,宇宙物质处于弥散状态,由于引力作用逐渐集中到某凝集中心周围,从而形成了星体。 设在凝聚过程中太阳物质总势能由0→—V_0,由于能量守恒,总动能相应升高,体系的温度由原来的0(K)→T(K)。太阳球体最外 All things on Earth bathed in the sunshine of the sun, live and work, continuous development and evolution. With the progress of science and technology, the mystery of the sun has been constantly revealed, the use of solar radiation put on the agenda. How does the sun radiate energy from this body? First, the sun is a hot body. A hypothesis of modern physics holds that before the formation of the stars, the matter in the universe was in a diffuse state, and due to gravitation, it gradually concentrated around a condensation center, forming a star. The total potential energy of the solar material set in the process of coalescence increases from 0 → -V 0 due to the conservation of energy and the total kinetic energy increases correspondingly. The temperature of the system changes from 0 (K) → T (K). The sun’s outermost sphere
