coordinates condition造句
例句與造句
- The synchronous coordinate condition is neither generally covariant nor Lorentz covariant.
- These constraints are known as coordinate conditions.
- Although the harmonic coordinate condition is not generally covariant, it " is"
- It must be combined with a coordinate condition, which is analogous to gauge fixing in other field theories.
- Harmonic coordinates in higher dimensions were developed initially in the context of general relativity by ( see harmonic coordinate condition ).
- It's difficult to find coordinates condition in a sentence. 用coordinates condition造句挺難的
- When choosing coordinate conditions, it is important to beware of illusions or artifacts that can be created by that choice.
- But coordinate conditions must not be generally invariant because they are supposed to pick out ( only work for ) certain coordinate systems and not others.
- The determinant of the metric tensor in a Kerr-Schild metric is negative one, which by itself is an under-determinative coordinate condition.
- This coordinate condition resolves the ambiguity of the metric tensor g _ { \ mu \ nu } \ ! by providing four algebraic equations that the metric tensor must satisfy.
- This coordinate condition resolves the ambiguity of the metric tensor g _ { \ mu \ nu } \ ! by providing four additional differential equations that the metric tensor must satisfy.
- And thus, dropping the minus sign, we get the "'harmonic coordinate condition "'( also known as the de Donder gauge after Th閛phile de Donder ):
- Naively, one might think that coordinate conditions would take the form of equations for the evolution of the four coordinates, and indeed in some cases ( e . g . the harmonic coordinate condition ) they can be put in that form.
- Naively, one might think that coordinate conditions would take the form of equations for the evolution of the four coordinates, and indeed in some cases ( e . g . the harmonic coordinate condition ) they can be put in that form.
- For example, the Schwarzschild metric may include an apparent singularity at a surface that is separate from the point-source, but that singularity is merely an artifact of the choice of coordinate conditions, rather than arising from actual physical reality.
- If one is going to solve the Einstein field equations using approximate methods such as the post-Newtonian expansion, then one should try to choose a coordinate condition which will make the expansion converge as quickly as possible ( or at least prevent it from diverging ).
