- Riemann space curvature 黎曼空间曲率
- Also, General Relativity defines non-inertia space-time as a space of Riemann. For Riemann space has positive curvature, we have to doubt about where the minus curvature space is. 广义相对论把非惯性时空定义为黎曼空间,但由于黎曼几何是正曲率空间,既然广义时空是对称的,我们必然要问,负曲率空间到哪去了?
- The article proves in detail the space curvature of the gravitational. field of central symmetry in vacuum. 本文给出在真空中中心对称引力场的空间曲率的详尽证明.
- On the basis of applying second-order tangential space and Riemann space in 3N dimension Euclid space [4], the writers have derived the integral variati- onal principles in Riemann form for first-order and second-order non- holonomic dynamical systems. 本文在引进3N维Euclid基本空间的二阶切空间及Riemann空间中,提出一、二阶非完整力学系统的积分变分原理的Riemann形式。
