The right humanity immerses in the heaven of heavens which oneself creates, forgets oneself, just like the astronomy expected many times such as well as the Earth history once performed the dissimilarity, came from the nameless interspace because the instantaneous interspace erupted the volume giant planetoid which formed, was raiding by the extremely high speed to our sky-blue Earth, moreover the track probably passed through the precise trajectory computation to resemble, 100% collisions to the Earth, launched in the entire human history the only globalization uniformization integration to save Earth's great campaign from this, but after all turned danger into safety, the humanity more and more discovered, each other was such is familiar with such need each other, therefore humanityAfter separates mutually repelled mutually has conquered mutually for several million years, finally under the rational impel has realized the final return unification, from this time on also did not have the language, the custom, the belief difference again, again also did not have the region, the skin color, consciousness barrier, the humanity finally to construct belonged to each earthman's Earth to unify the extremely happy heaven!

正当人类沉浸在自己一手缔造的极乐世界中，忘乎所以的时候，正如多次天文预料的那样以及地球历史曾经上演的一样，一颗来自无名星际间由于瞬间的星际爆发所形成的体积巨大的小行星，正以极高的时速袭向我们蔚蓝色的地球，而且轨道好像经过精确弹道计算似的，百分之百的撞向地球，由此展开了整个人类历史上唯一一次全球化一致化整体化拯救地球的伟大战役，而当一切都化险为夷之后，人类越来越发现，彼此是这样的熟悉这样的需要彼此，于是人类在互相分离互相排斥互相征服了几百万年之后，终于在理性的感召下实现了最终的回归统一，从此再也没有了语言、风俗、信仰的差别，再也没有了地域、肤色、意识的障碍，人类终于构建成了属于每一个地球人的地球统一极乐天堂！

The picosatellite is characterized by small volume, light weight and low power consumption. Based on these characteristics, a designed micro sun sensor is used to measure the sun vector which is then compared with the sun vector calculated from the orbit propagator. In such a way the picosatellite attitude angle can be obtained.

Based on the ISC earthquake catalogue data, according to the orbit equations of two-body-problem and the perturbation theory of celestial mechanics, we could determine the projection pole of the sun, and thus calculate the zenith distance from the sun to the epicenter. After calculating all the earthquakes on their zenith distances, we could get the distribution of the solar zenith distance versus the occurring probability of earthquakes.
