Ten arguments for the essence of special relativity

In searching for the essence of special relativity, we have been gradually accumulating ten arguments focusing on one fundamental postulate based on quantum mechanics.A particle is always not pure. It always contain two contradictory fields, $\phi(\vec{x},t)$ and $\chi(\vec{x},t)$,which are coupled together with the symmetry $\phi(-\vec{x},-t)\longrightarrow\chi(\vec{x},t)$ and $\chi(-\vec{x},-t)\longrightarrow\phi(\vec{x},t)$.
