标题： Intrinsic time in Wheeler-DeWitt conformal superspace

摘要： 在几何动力学中，通过使用缩放的狄拉克映射获得了一种固有时。 通过添加一个背景度规，可以构造一个标量场。 它适合扮演固有时的角色。 由于共形变量是物理变量，所以柯西问题成功地得到了解决。 首先，作为空间度规行列式的对数的固有时，由米斯纳应用于宇宙学问题。 在时空的常平均曲率切片条件下，存在全局时间。 超曲面的体积和所谓的平均耶克斯时间是共轭的正则对。 因此，从意义上说，体积就是固有的全局时间。 宇宙学中实验观测到的红移是其存在的证据。 显示英文摘要

摘要： An intrinsic time in Geometrodynamics is obtained with using a scaled Dirac's mapping. By addition of a background metric, one can construct a scalar field. It is suitable to play a role of intrinsic time. Cauchy problem was successfully solved in conformal variables because they are physical ones. First, the intrinsic time as a logarithm of determinant of spatial metric, was applied to a cosmological problem by Misner. A global time is exist under condition of constant mean curvature slicing of spacetime. The volume of hypersurface and so-called mean York's time are canonical conjugated pair. So, the volume is the intrinsic global time by its sense. The experimentally observed redshift in cosmology is the evidence of its existence.
