Southerly gales brought severe windshear and turbulence to the airport . as southerly gales blew across the northeast - southwest oriented hilly ranges over lantau , streaks of low wind flow emanated from the hills while streaks of high wind flow appeared downwind of the gaps 当晚主要吹南风,强度达烈风程度,为机场带来强烈风切变和湍流。当这些烈风程度的南风吹越大屿山上东北走向西南的山脉时,在山脉及山谷的下游分别形成条纹状的弱气流及强气流。
Besides this , a bypass multi - mode waveguide were used to improve attenuation efficiency and reduce power consumption . based on buried channel structure , the simulation software beamprop ? produced by rsoft corp shows some better results than the original device : attenuation range over 20 higher , insertion loss merely 1db higher and the calculated power consumption is only 25mw 加入的旁路吸收波导和多模区间距为零时最大衰减对应的温度为60 ,衰减增加了20db以上,功耗也增加了1倍,插入损耗比间距为1 , 2 m时增加约0 . 4db ,比没有旁路波导时插入损耗增加了约ldb 。
This paper exhausts fully adjustable factor which could amend the dynamic function in fuzzy control system , and that traditional algorithms select factors with intercession is easy to get a partial solution , so this paper presents a new method to select factors based on genetic algorithm . this method has a large range over covered the solutions which could benefit to search the best solutions . it has great character and advantage 本文充分阐述了可调整因子在模糊控制中能够改善了系统的动态性能,并根据传统的优化算法在选取控制因子时是从单个初始值迭代求取最优解的、很容易陷入局部最优解这一问题,提出了一种基于遗传算法的可调整因子的选取方法,这种方法覆盖面比较大,有利于全局择优。
