The results show that according to the changing characteristics of the four seasons in Zhejiang Province,autumn and winter began later,while spring and summer started earlier than before; the duration of summer lengthened,while the duration of winter shortened,and there were great changes in summer and winter but small changes in spring and autumn. Seen from the spatial distribution of beginning date and duration of the four seasons,the correlation in middle and northern Zhejiang was better than that in southern Zhejiang.展开更多

However, we still don’t have definitive answers. In this paper, we substantiate the idea of the existence of a Primary Parent Particle, constituents of the medium of primary matter before the Big Bang and describe its structure, consisting of three Beginnings united in the form of Borromeo rings. We derived a generalization of the Bohr-Sommerfeld quantization rules on the multidimensional case and considered problems of the embedding spaces into the each other based on the Nash theorems. Assuming that at the distances occupied by the triad we can consider the space Euclidean flat, we introduce quantum mechanical equations describing them. The problems of constructing the theory of quantum gravity and Dark matter radiation are considered separately. As part of our approach, we describe the acceleration of the Universe created by Dark Energy during expansion. We criticize principle of dualism, which can be used only for linear theories, but is not applicable to nonlinear theories. We investigated various distributions of dark matter densities and the gravitational potentials induced by them in galaxies and velocities for rotation curves. The main goal in the article was to show self-deployment of the Universe and its origin before Big Bang.展开更多
