本文第四章研制设计了一包含海洋表面边界层和大气辐合反馈过程的热带太平洋海气耦合异常模式,进而利用该模式对ENSO循环进行了较为真实的模拟,通过对模式ENSO循环的演变特征及其形成机制的细致分析,建立了-ENSO循环的非线性分析模式,并提出了ENSO循环形成的一种更为客观的理论,指出:1)和观测事实类似,模式ENSO循环确实涉及了三种主要时间尺度过程即LF、QB和AC,其中LF为3-4年主周期振荡,QB占总方差10~20%;2)ENSO循环的正反馈机制是不稳定海气相互作用过程,且这一不稳定过程的发展在暖态中明显强于冷态;3)ENSO循环的负反馈机制在冷暖态中表现不同,在冷态消亡过程中,这种负反馈过程主要表现为西边界反射产生的时滞效应,但在暖态消亡过程中不存在类似的时滞效应,其负反馈过程主要表现为在海气耦合不稳定充分发展时伴随的赤道两侧冷水上翻过程的加强以及非线性过程的衰减作用抑制了不稳定的发展并最终使得系统回复至冷态;4)ENSO循环的3-4年主周期振荡是一非线性系统的自激振荡现象,其形成是线性系统的本征模即准两年振荡通过非线性机制产生的周期加倍所致,其中&单向性&大气辐合反馈加热过程对其形成至关重要;5)虽然年循环过程对ENSO循环形成没有本质影响,但它可明显影响ENSO循环的具体振幅和位相,使得ENSO对季节循环有明显的&锁相&特征,并且也使得ENSO循环在振幅大小和时间长短方面呈现出明显的不规则性。

So the technique of uncooled microbolometer infrared imaging has become one of the main points from now on. In the paper uncooled microbolometer infrared imaging system is studied from focal plane character, image dealing and application. The details are in the following: On uncooled microbolometer infrared focal plane aspect: first, the work principle of microbolometer, manufacturing technology of microbolometer infrared focal plane, temperature balance equation of microbolometer detector are analyzed. The performance of microbolometer detector is predicted by model. Second, the infrared focal plane is the core of infrared system, whose quality can determine the performance of the system. It is the precondition that the high quality of every detective unit maintains the qualification of the focal plane. The even degree of detective units has great influence on imaging characters if the other characters of detective units are normal.
本文以非致冷微测辐射热计红外成像系统为对象,从焦平面特性、图像处理和红外系统应用方面展开分析、研究,具体内容如下;在微测辐射热计红外焦平面方面,首先分析了微测辐射热计的工作原理、微测辐射热计红外焦平面的工艺制作、微测辐射热计探测单元的温度平衡方程,根据有关参数对其特性进行建模预测;其次,红外焦平面是红外系统的核心,它的质量的好坏直接决定系统性能,因此保证其各探测单元的高性能是维护焦平面品质的前提,在探测单元其它特性正常的情况下,各探测单元之间特性的均匀程度对系统成像性能有极大影响,为此本文提出自适应滤波多项式焦平面非均匀性校正算法从软件角度解决焦平面的固有的噪声问题。
