1. We found a new mechanism for dynamical Supersymmetry breaking. And we constructed particle-physics models based on such a new mechanism.2. We constructed various inflation models in supergravity and discussed the primordial black-hole formation in early universe.3. We investigated cosmological consequence of dilation presents in some string theories and pointed out a possibility that thee dilation is the dark matter in our universe.4. We found a particle-physics model which naturally explains the large neatrino mixing observed by super kamicbande experiments.5z We constructed a particle-physics model for the superheavy particle introduced to explain the ultra-high energy cosmic rays.

1.我们发现了动力学超对称破缺的新机制。并在此基础上构建了粒子物理模型.建立了超引力下的各种暴胀模型，讨论了早期宇宙中原初黑洞的形成.我们研究了一些弦理论中膨胀的宇宙学后果，并指出了这种膨胀是我们宇宙中暗物质的可能性.我们发现了一个粒子物理模型，它自然地解释了超级kamicbande实验观察到的大neatrino混合。5z我们为超重粒子构建了一个粒子物理模型，用于解释超高能宇宙线。
