例句與造句

1. The Bianchi identity associated with this partial gauge invariance is wrong.
2. Of particular relevance to general relativity are the algebraic and differential Bianchi identities.
3. However, in order to define the Hodge star, the Laplacian, the first Bianchi identity and the Yang-Mills functional, one needs the bundle metric.
4. This means that 2-brane and 5-brane charge are the violations of the Bianchi identities for the dual C-field and original C-field respectively.
5. The last identity was discovered by Ricci, but is often called the " first Bianchi identity ", just because it looks similar to the Bianchi identity below.
6. It's difficult to find bianchi identities in a sentence. 用bianchi identities造句挺難的
7. The last identity was discovered by Ricci, but is often called the " first Bianchi identity ", just because it looks similar to the Bianchi identity below.
8. As is the case with magnetic monopoles in electromagnetism, this source also invaliditates the dual Bianchi identity as it is a point at which the dual field is not defined.
9. They will obey the usual symmetry properties; for example, the curvature of the connection will be anti-symmetric in the last two indexes, and will satisfy the second Bianchi identity.
10. The Bianchi identities of the Ramond-Ramond gauge potentials C _ { 2k-1 } can be violated by adding sources \ rho, which are called D ( 8 & minus; 2 " k " )-branes
11. The above Bianchi identity is interpreted to mean that the Dp-brane is, in analogy with magnetic monopoles in electromagnetism, magnetically charged under the RR " p "-form " C " 7 & minus; " p ".
12. From the above Bianchi identity we see that a D8-brane is a domain wall between zones of differing " G " 0, thus in the presence of a D8-brane at least part of the spacetime will be described by the Romans theory.
13. Conversely, except in dimension 2, if the curvature of a Riemannian manifold has this form for some function " K ", then the Bianchi identities imply that " K " is constant and thus that the manifold is ( locally ) a space form.
