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.

为了打开一个新的观测/实验窗口，我们从宇宙物理现象学和超弦/超引力两个方面对轴子进行了研究，并发表了200多篇论文。主要成果有：通过数值模拟证明了由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其可观测性；推导了轴子的参数范围，解决了高能伽马射线观测与红外背景观测之间的冲突；评估由重模衰变产生的轴子对宇宙微波背景的影响，并在此基础上推导额外维度紧化的约束，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。
