A Medium Term Note is a debt note that usually matures in 5-10 years, but the term may be as short as one year or as long as 50 years. They're normally issued on a floating basis such as Euribor +/- basis points. When they are issued in a Euro-currency, they are called "Euro Medium Term Notes".The notes are usually connected to a Medium Term Note Program, which is a funding program used by issuers to receive bond debt funding on a regular and continuous basis.

中期票据实际上常常与中期票据项目联系在一起，中期票据项目是一种发行人可以在某一核准额度内自主持续发行债券的融资项目，这种项目的优点是赋予发行人更大的灵活性，一旦监管部门核准该发行人某一发行额度，该发行人可以在相当长的时间内(1-2年)自主选择发行时间和期限在债券市场上融资，尽管该债券称为"中期债券"。

The basis function of the coinjection of Nitrogen and steam is increasing the displacement volume and supply the displacement energy on the basis of Nitrogen, the result of the numerical simulation showed that, after the coinjection of Nitrogen and steam (the optional aqueous Nitrogen ratio was 1: 20～1: 50), the theamal readius increased from 30m to 55m more or less, the recovery ratio increased by 5～10％. The production effect of the high cycles steam stimulation will be improved and the pattern infill will be avoided and the economic results will be improved. 4. The poor result of steamflood is another problem. On the basis of the analysis of the foamer mechanism in the propayation, movement and stabilization, this paper showed that the main meachanism of the increasing recovery of the Nitrogen foam and steamflood was the increasing displacement factor and oil displacement efficiency.

三针对蒸汽吞吐加热半径有限（一般30m左右）而蒸汽吞吐轮次已高达5轮以上的具体情况，将氮气与蒸汽混合（套管环空中注氮气，油管中注蒸汽）进行吞吐可增加加热半径1～2倍以上；在对原油流变性研究基础上，对氮气蒸汽原油体系状态进行了分析，指出了氮气在油藏中基本上是以气相方式存在；热氮混合吞吐的基本作用为扩大波及体积和提供驱油能量；在此基础上所进行的热氮混注数值模拟研究表明：蒸汽中加入氮气后（最佳汽氮比为1：20～1：50），加热半径从30m增至55m左右，采收率可提高5～10％以上，大大改善了高轮次蒸汽吞吐的生产效果，可避免大规模井网加密，提高了经济效益。

Agriculture is the basis of the national economy and food supply is the "basis of basis".

农业是我国国民经济的基础，粮食是基础的基础。

If the initiator handles basis finance assets make over as going bail for a financing, basis finance assets make over can only report as funded debt on balance sheet , but great majority condition puts in assets the asset-banked securities structuring original intention is by structuring the purpose "going bankrupt putting the form outside financing and risk isolation under isolated reach " but , sell only problem that can involve in combining range to if SPV bring into to the initiator handling time only when the assignor acts as the basis finance assets column.

笔者认为，国外在长期实践中形成的研究成果值得我们借鉴，但这些研究成果在理论和实践中仍存在一些问题需要进一步探索和研究，在制定我国资产证券化的相关会计规范时应予以充分考虑。

By finding a set of basis, we use matrices of transformation under a set of basis to describe the structure of the Galois group. If a normal extension has a normal basis, then it is simpler to describe the structure of Galois group in this method.

因此寻找一组基，我们利用线性变换在基下的矩阵来描述Galois群的结构，特别地，当正规扩张存在一组正规基时，用这种方式表示Galois群的更加简单。

In the paper, on the basis of aggregation of previous studies, the development of optical technology and development trends at home and abroad are introduced, the principle of Fresnel lens is summarized. In accordance with its principle, circle equidistant steps Fresnel lens design is described. And on this basis, based on Fresnel design, also based on a continuous upward spiral of the plane curve concept, incidence surface and the backlight is set up to greet Archimedes - Fresnel lens design formula and the Second parabolic type Fresnel lens design formula, and on this basis, the advantages and disadvantages of the three designs is discussed.
