问题：哪位大哥，大姐，世外高人帮忙翻译一下这个句子呀！谢谢了！拜托了！ 
原文:“此外值得一提的是,传统理论认为只有当扑翼飞行或当猛禽格斗时,才会应用到非定常涡流:翼梢处的羽毛会一根根向不同方向张开,使翅膀外侧产生许多空隙,起到提高升力的作用。而当鸟类翱翔时,仅应用定常附着流:翼梢处的羽毛会并拢,形成一个完整的翼面并向上弯曲,最终形成一个与翅膀垂直的完整翼面。外形酷似翼梢小翼,起到减小诱导阻力的作用(传统翼梢小翼也正是基于这种观念而发明的)。然而这种理论显然是错误的,是不符合事实的。”译为:“Inaddition,itisworthmentioningthatthetraditionaltheorybelievestha原文:“此外值得一提的是,传统理论认为只有当扑翼飞行或当猛禽格斗时,才会应用到非定常涡流:翼梢处的羽毛会一根根向不同方向张开,使翅膀外侧产生许多空隙,起到提高升力的作用。而当鸟类翱翔时,仅应用定常附着流:翼梢处的羽毛会并拢,形成一个完整的翼面并向上弯曲,最终形成一个与翅膀垂直的完整翼面。外形酷似翼梢小翼,起到减小诱导阻力的作用(传统翼梢小翼也正是基于这种观念而发明的)。然而这种理论显然是错误的,是不符合事实的。”译为:“Inaddition,itisworthmentioningthatthetraditionaltheorybelievesthatunsteadyvortexcanbeappliedonlyduringbirdflapping–wingflight,orduringfightin ,andtherebymanygapscanbegeneratedoutsidethewing,therebyplayingtheroleofimprovingtheliftingforce.Whenbirdsfly,onlysteadyattachedflowcan ,finally,acompletewingsurfaceverticaltothewingcanbeformed.Theappearanceissimilartothewinglets,anditplaysaroleofreducingtheinduceddrag(traditionalwingletsarealsodevelopedbasedonthisconcept).However,thistheoryisobviouslywrongandisnotconsistentwiththefacts.”原文:“当鸟类翱翔时在翼梢处产生非定常涡流,以便提高升阻比。”译为:“Unsteadyvortexwillbegeneratedatthewingtipswhenbirdsfly,therebyimprovingthelift-dragratio.”原文:“非定常翼梢小翼模仿了鸟类翼梢的特殊结构,使飞机可以借助翼尖涡产生升力,大大提高了飞行效率。”译为:“Unsteadywingletimitatesthespecialstructureofbird'swingtip,andtheaircraftcangenerateliftingforcebytheaidofwingtipvortices,therebygreatlyimprovingtheefficiencyoftheflight.”请问如何压缩为:“传统理论认为只有当鸟类扑翼飞行或当猛禽格斗时,才会应用到非定常涡流,而当鸟类翱翔时,仅应用定常附着流(传统翼梢小翼也正是基于这种观念而发明的)。然而这种理论显然是错误的,是不符合事实的。当鸟类翱翔时翼梢处会产生非定常涡流,以便提高升阻比。非定常翼梢小翼模仿了鸟类翼梢的特殊结构,使飞机可以借助翼尖涡产生升力,在传统翼梢小翼的基础上进一步提高了飞行效率。”谢谢了!拜托了!
回答：The tradional theory believes that unsteady vortex can be applied only during bird flapping –wing flight, or during fighting of raptor. When birds fly, only steady attached flow can be applied(traditional winglets are also developed based on this concept).However, this theory is obviously wrong and is not consistent with the facts.Unsteady vortex will be generated at the wingtips when birds fly, thereby improving the lift-drag ratio.Unsteady winglet imitates the special structure of bird's wingtip, and the aircraft can generate lifting force by the aid of wingtip vortices, thereby greatly improving the efficiency of the flight.
