Abstract: A forecast operation method for lowering the reservoir flood limited water level considering forecast uncertainty is disclosed. The flood forecast feasibility of a reservoir controlled basin is analyzed, and the principle of maximum entropy is adopted to identify forecast error distribution; A framework of operation rules for lowering the flood limited water level at the flood rising stage is formulated by using an idea of pre-release, and the forecast operation framework is optimized to obtain forecast operation solution optimization point sets; All optimization point sets that achieve the upstream and downstream flood control safety in case of maximum forecast errors are screened out from the forecast operation solution optimization point sets; and finally, in comprehensive consideration of forecast errors and different preferences of decision makers, the optimal forecast operation solution points are evaluated by using a binary comparison method and a fuzzy optimization model.

Abstract: The present disclosure discloses a polarization-maintaining hollow-core antiresonant fiber. An inner layer of the polarization-maintaining hollow-core antiresonant fiber includes first thin walls, second thin walls, and third thin walls. The present disclosure introduces high birefringence through the wall thickness difference between the first thin wall and the second thin wall, and effectively amplifies a birefringence effect achieved by the wall thickness difference through quasi multi-symmetric structures of the first thin walls and the second thin walls. In addition, the present disclosure reduces the transmission loss and suppresses the leakage of light through the inner layer, particularly, the third thin walls of the inner layer, so that the fiber of the present disclosure realizes polarization maintaining, and meanwhile, reduce the loss as far as possible.
