摘 要:
据实验检测和理论计算，论证了现时中微子的超对称伴子“中性微子”U↑-e^0（q2，g↑-）是宇宙暗物质的最佳候选粒子．认为超新星爆炸释放的暗能量，迫使宇宙背景光子热平衡态的温度T、压强p上升．将压强类比为“反引力”，当“反引力”（压强）大于引力，则宇宙将加速膨胀；当“反引力”小于引力，则宇宙将收缩．[著者文摘]

Abstract:
On the bases of experimental measurement and tests and theoretical calculation, the supersym- metry companions of present neutrinos, neutralinos U↑-e^0B（q2, g↑-）, are proved to be the best candidate particles of dark matter in the universe, and the energy released by supernova explosion is thought to make the tempera- ture T and the pressure p of the thermal equilibrium state of universe background photons go up. If pressure is compared to “anti-gravitation”, when“anti-gravitation” （pressure） is bigger than gravitation, the universe will expand, and when “anti-gravitation” is smaller than gravitation, the universe will contract.[著者文摘]
Key words:
dark matter; neutralino; dark energy; thermal equilibrium state of photons; anti-gravitation; u-niverse fate
