conjugate momentum造句

例句与造句

1. Heisenberg's uncertainty principle quantifies the inability to precisely locate the particle given its conjugate momentum.
2. This conjugate momentum is the magnitude " L " of the angular momentum, as shown by the Hamiltonian equation of motion for ?

5. It turns out that \ tilde { E } ^ a _ i is the conjugate momentum of A _ a ^ i, and together these form Ashtekar's new variables.
6. It's difficult to find conjugate momentum in a sentence. 用conjugate momentum造句挺难的
7. Taking the partial time derivative of the definition of the Hamiltonian density above, and using the chain rule for implicit differentiation and the definition of the conjugate momentum field, gives the continuity equation:

9. We define the conjugate momentum of the scalar field with the usual \ tilde { \ pi } = \ delta L / \ delta \ dot { \ varphi }, the Hamiltonian can be rewritten as,
10. It can be shown that six Einstein equations describing time evolution ( really a gauge transformation ) can be obtained by calculating the Poisson brackets of the three-metric and its conjugate momentum with a linear combination of the spatial diffeomorphism and Hamiltonian constraint.
11. As in Hamiltonian mechanics where every generalized coordinate has a corresponding generalized momentum, the field has a "'conjugate momentum field "', defined as the partial derivative of the Lagrangian density with respect to the time derivative of the field,
12. For example, if we use polar coordinates " t, r, ? " to describe the planar motion of a particle, and if " L " does not depend on " ? ", the conjugate momentum is the conserved angular momentum.
13. In Ashtekar formulation the gauge field A _ a ^ i ( x ) is the configuration variable ( the configuration variable being analogous to q in ordinary mechanics ) and its conjugate momentum is the ( densitized ) triad ( electrical field ) \ tilde { E } ^ a _ i ( x ).
14. In the ADM formulation of general relativity one splits spacetime into spatial slices and time, the basic variables are taken to be the induced metric, q _ { ab } ( x ), on the spatial slice ( the metric induced on the spatial slice by the spacetime metric ), and its conjugate momentum variable related to the extrinsic curvature, K ^ { ab } ( x ), ( this tells us how the spatial slice curves with respect to spacetime and is a measure of how the induced metric evolves in time ).
