We calculate, in a relatively explicit way, the Hamiltoniansystems that arise from the Evens–Lu construction of homogeneousPoisson structures on both compact- and noncompact-type symmetricspaces. A corollary is that the Hamiltonian system arising inthe noncompact case is isomorphic to the generic Hamiltoniansystem arising in the compact case. In the group case, thesesystems are also isomorphic to those arising from the Bruhat–Poissonstructure on the flag space, and hence, by results of Lu, canbe completely factored. 相似文献

We present the experimentally determined optical bend loss for random hole optical fibers in the spectral range 1520 to 1570 nm induced by wrapping the optical fiber around a fixed diameter mandrel. The optical losses are compared to those obtained for a single-mode fiber and a multimode fiber using the same bending procedures. The bending induced optical losses in the random hole optical fibers were several orders of magnitude lower than for the single-mode fiber and were about 1 order of magnitude lower than for the multimode fiber. 相似文献

Lifetime of levels up to 22+, have been measured in 78Kr and an oblate shape is assigned to the ground state using the CSM and the configuration dependent shell correction calculations.
Calculations further show that 78Kr is highly γ-soft nucleus. The experimental Q
t values coupled with theoretical calculations indicate an oblate shape for 78Kr at low spins and triaxial shape at higher spins 相似文献
