负曲率 meaning in Chinese
negative cruvature
negative curvature
Examples
- Some bundles over nonnegatively curved manifolds
非负曲率流形上的丛 - The complete open nonnegatively curved riemannian manifolds with souls of codimension one
核心的余维数为1的具非负曲率完备非紧黎曼流形 - Conformal deformations for prescribing scalarcurvature on riemannian manifolds with negative curvature
负曲率流形上给定数量曲率的共形形变 - 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 manufacture system of filament winding ( fw ) and fiber placement ( fp ) is the one of advanced equipment for frp products . it can be used to produce the products of the positive curvature gyration bodies , such as container cylinder , oil tank , tube , orb , cone , assembled body and so on . furthermore , it is more suited to machining some products of the complex bodies such as the surfaces of the negative curvature gyration bodies , the shell components which have slots and reinforced tendons
纤维缠绕/铺放联合制造系统是纤维增强塑料( frp )制品生产的先进制造装备之一，可用于制造如圆筒容器、储罐、管、球、锥形体或组合形体等正曲率回转体的制品，更适用于制造含有负曲率的回转体表面、具有深槽、加强筋的壳体构件等外形相对复杂的纤维增强塑料制品。
