从近期的角度回顾了中微子物理学的现状。在回顾了具有非零质量和味道混合的现代中微子物理学的诞生之后，我总结了MNS矩阵的2-3、1-2和1-3扇区中混合参数的测量现状。然后，我描述了揭示混合角测量值中的规律性（如果有的话）的尝试；主要是复习。然而，θ_{23} 与第二个八分圆的可能较大偏差可能会引发人们对轻子混合角的三角形关系的兴趣。在我演讲的后半部分，描述了确定质量等级和测量轻子小林-益川相 $\delta$ 的一些观点。最后，我讨论了快速发展的高能中微子天体物理学新领域的前景，以及正在兴起的宇宙学和粒子物理学的新精密时代。我以乐观的推测作为结束语。
The current status of neutrino physics is reviewed with some near future perspective. After recollecting the birth of modern neutrino physics with nonzero masses and flavor mixing, I summarize the present status of measurement of the mixing parameters in 2-3, 1-2, and 1-3 sectors of the MNS matrix. Then, I describe the attempts to uncover the regularities, if any, in the measured values of the mixing angles; mostly reviewing. Yet, a possible large deviation of \theta_{23} to the second octant may trigger interests in the triangle relation of the lepton mixing angles. In the latter part of my lecture some perspective of determination of the mass hierarchy and measurement of lepton Kobayashi-Maskawa phase $\delta$ are described. Finally, I discuss the prospects of the new, fast developing field of high-energy neutrino astrophysics, and the emerging new precision era of cosmology and particle physics. I conclude with optimistic speculations.
