In order to open up a new observational/experimental window to the ultimate theory, we have studied axions from both the cosmophysics phenomenology aspect and the superstring/supergravity aspect and have published more than 200 papers. The main achievements are demonstarations of the axion bose nova phenemenon caused by a rotating black hole by numerical simulations and the discovery of its observability by gravitational wave experiments, derivation of a parameter range for axion to resolve the conflict between the high energy gamma-ray observations and the infrared background observation, evaluations of the influences of axions produced by the decay of heavy moduli on cosmic microwave background and derivation of constraints on the compactification of extra-dimensions on the basis of this estimation, derivation of constraints on elementary particle models from cosmological influences of axionic isocurvature perturbations and topological defects.

为了打开终极理论新的观测/实验窗口，我们从宇宙物理现象学方面和超弦/超引力方面对轴子进行了研究，并发表了200多篇论文。主要成果是通过数值模拟演示了旋转黑洞引起的轴子玻色新星现象，并通过引力波实验发现了轴子的可观测性，推导了轴子参数范围，解决了高能伽马射线观测之间的冲突和红外背景观测，评估重模衰变产生的轴子对宇宙微波背景的影响以及推导对宇宙微波背景的致密化约束在此估计的基础上，从轴子等曲率扰动和拓扑缺陷的宇宙学影响中推导基本粒子模型的约束。
