The above work gives a quite complete and systematic analysis of the aam balance in a long time , including climatic and anomalous characteristics , and links the aam and its transportation , earth - atmosphere angular momentum exchange ( mountain torque and friction torque ) with lod and sst . the intimate link is confirmed between aam and lod , el nino 以上工作对一个较长时间内的大气角动量平衡各个方面进行了较完整系统的分析，包括多年平均和异常特征分析，并将角动量及其输送、地气系统角动量交换(摩擦和山脉力矩)与日长、尼诺三区海温相联系，证实了大气角动量与地球自转变化、厄尔尼诺事件间的密切联系。
This section begins with the analysis of the cash flow of the two most elementary products - mortgage pass through securities ( mpt ) and collateralized mortgage obligations ( cmo ) , and describes the difference between the function mechanism and the ability of resisting risk . then , based on the above analysis , this article tries to invent an new cmo product which goes by the name of adjustable amortization mortgage ( aam ) and can effectively counteract the extension risk when interest rate goes up . at the same time , this article also indicate some problem which should pay special attention to in practical application and put forward some corresponding market promotion strategy 本章首先通过对两种最基本的抵押证券? ?抵押贷款传递证券（ mpt ）和抵押担保证券（ cmo ）现金流量变化的分析，研究其运行机制和防御风险的功能差异，接着在以上分析的基础上，文章尝试提出了一种能够有效化解利率上升环境中延期风险的新型证券品种? ?可调整分期付款额的抵押担保证券（ adjustableamortizationmortgage ，简称为aam ）的设想，但同时也指出了这种抵押担保证券在实际应用中应该特别注意之处，并提出了相应的市场推广策略。
The main results and conclusions acquired from the dissertation are as follows : ( 1 ) aam templates with nano - pore arrays were fabricated in different anodic oxidative conditions by anodic oxidation of aluminum foils , so the pores in aam templates might have different diameters , different densities , different depths and different aspect ratios 主要研究程果和结论如下： ( 1 )在硫酸、草酸和磷酸电解液中，在不同的阳极氧化条件下制备出具有不同大小、密度、深度和纵横比的纳米孔阵列aam模板。
