The dynamical model included the effects of the earth non-spherical shape, atmospheric drag, solar radiation pressure as well as lunar and solar perturbations.
在建立动力学模型中，计及了地球扁球形的摄动、大气阻力、太阳辐射压的效应以及日月引力摄动。
This radiation pressure is thought to shape the tails of comets and is useful for pushing solar sails in space.
这种辐射压力被认为是彗尾形成的原因。 另外，它也是太阳帆在太空中前进的动力来源。
Once the sun and planets took shape, heat became readily available in the form of solar radiation, asteroid impacts, and gravitational pressure.
太阳和行星成形后，太阳辐射、小行星撞击以及重力压力继续提供着热量。
The sun was high temperature, high pressure, bears tremendous amounts of energy by light to the cosmic radiation; solar energy is an important human new non-polluting energy.
太阳高温、高压，蕴藏着巨大的能量，不断地通过光线向宇宙放射，太阳能是人类重要的无污染新型能源。
