The Golden Fleece king athamus of northern greece had two children, phrixus and helle.after he left his first wife and mar ried ino ,a wicked woman ,the two children received all the cruel treatment that a stepmother could devise,at one timethe kingdom was ruined by a famine.ino persuaded her credulous husband into believing that his son ,phrixus ,was the actual cause of the disaster,and should be sacrificed to zeus to endit.the poor boy was then placed on the altar and was about tobe knifed when a ram with golden fleece was sent down by thegods and carried off the two children on its back.as they flew over the strait that divides asia from europe,helle ,faint at the vast expanse of water below,fell into the sea and was drowned.thus the sea of helle ,hellespont,became the ancient name of the strip of water.her brother kept on and arrived in colchis on the eastern shore of the black sea.there he sacrificed the ram to zeus and gave its golden fleece to king aeetes ,who nailed it on a sacred tree and put a sleepless dragon in charge .

金色的羊毛希腊北部国王阿塔玛斯有两个孩子，法瑞克斯和赫勒。当国王离开第一个妻子和一个名叫伊诺的坏女人结婚后，两个孩子受到后母残忍虐待，整个王国也受到毁灭性瘟疫的侵袭。伊诺在爱轻信的丈夫耳边进谗言，终于使国王相信：他的儿子法瑞克斯是这次灾害的罪魁祸首，并要将他献给宙斯以结束瘟疫。可怜的孩子被推上了祭坛，将要被处死。正在此时，上帝派了一只浑身上下长着金色羊毛的公羊来将两个孩子驮在背上带走了。当他们飞过隔开欧洲和亚洲的海峡时，赫勒由于看到浩瀚的海洋而头晕目眩，最终掉进大海淹死了。这片海洋古时候的名称叫赫勒之海，赫勒拉旁海峡便由此而来。金色公羊驮着法瑞克斯继续向前飞去，来到了黑海东岸的科尔契斯。在那里，法瑞克斯将公羊献给了宙斯；而将金羊毛送给了埃厄忒斯国王。国王将羊毛钉在一棵圣树上，并派了一条不睡觉的龙负责看护。

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明：1、强层化季节的陆架海水体一般呈现显著的三层热盐结构，在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层；2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制，而在潮流底边界层内，潮混合是水体热量、物质、动量与能量垂直交换的主要机制；3、潮混合影响的深度由潮流大小决定，在黄海，一般可达10-15 m，因此，在水深较深的区域，在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域，这显著抑制水体内物质的垂直通量，为物质垂直交换的瓶颈，而在水深较浅的区域，潮混合影响范围可至跃层底部，因此物质在跃层以下整个水体中混合非常均匀，当跃层内间歇性强混合发生时，可以产生显著的跨跃层物质输运；4、近底潮致强湍流耗散缓慢地向上传播，底上不同深度处垂直湍扩散系数也具有显著的位相差异，且二者均随时间呈现四分之一周日周期的变化；5、在地形较为平坦的中央海盆区，内波活动非常微弱，因此跃层内湍流混合非常弱，垂直扩散系数为分子扩散水平，跨跃层物质通量受到显著抑制，而在地形变化较为显著的局地陆坡区，内波活动非常活跃，除内潮的影响外，高频内波与内孤立波的影响也很显著，因此跃层内存在很强的间歇性强混合，内孤立波存在的区域，水体湍流混合显著增强。

PID control has been successfully used in many fields such as aviation, spaceflight, missile and other industry control system. The study object in the thesis is missile that flies hedgehopping over sea at minimum altitude. Many interference problem must be solved when missile flies at minimum altitude, otherwise the missile would be dangerous of bumping into the sea under the circumstances of bad weather and wave. The different kinds of interference factors are contradictions with requirements of control system, which can not be solved by PID control.
