极限

The fundamental compute region B is determined and self-similarly mapped into the upper half plane by using the homeomorphic affine transformationθ, so the fractal images of the upper half plane, square limit, and circle limit can be constructed.

周期化动力平面或参数平面，确定基本计算区域，应用同胚仿射变换将基本计算区域自相似地映射到上半平面，进而构造方极限和圆极限分形图。

Let be continuous on ,and .If the limit exists and have finite value , the value is the improper integral of on ,which is denoted by,that is

定义1 设函数在区间上连续，取，如果极限存在且为有限值，则此极限为函数在无穷区间上的反常积分，记作，即

If the limits of and are both or infinity as approaches, then exists or does not exist ,which is called the indeterminate form and represented by or .

如果当时，两个函数都趋于零或部趋于无穷大，那么极限可能存在，也可能不存在。通常把这种极限叫作未定式，并分别简记为，或。

The conclusion is that the present economic level of China is approximately equal to that of the developed countries in 1970s, and the present Chinese FDI outflow is approximately equal to that of the developed countries between 1960s and 1970s, and that the Chinese FDI outflow lags behind its economic development. In its demonstration of the industrial transfer limit theory, the paper puts forward its main viewpoint, namely, FDI is a means of transferring behindhand industry and heightening industrial structure adopted by developed countries, but this type of industrial transfer will not move in a cycle and the limit of the transfer will occur inevitably. In other words, FDI is not a means of improving industrial structure for such big developing countries as China and India. The paper, too, advances the theory of institution advantage, holding that the development of Chinese TNCs will not be explained reasonably unless institution advantage is entered into the OIL paradigm. This theory enriches and complements the theory of TNC.

这种研究在笔者所查阅的资料文献中尚属少见，其基本结论是，中国的经济发展相当于发达国家1970年代的水平，但中国对外的FDI相当于其1960 ~1970年代的水平，相显滞后；本文论证了产业转移极限论，主要观点是，对外进行FDI是发达国家转移落后产业，提升自己产业结构的手段，但这种产业转移不能顺次循环下去，必然会出现转移的极限，即对外直接投资不会是中国、印度等较大的发展中国家提升产业结构的手段；本文还提出了制度优势论的观点，即在OIL范式中，还须增加制度优势，方能对中国的跨国公司成长做出合理的解释，这是对跨国公司理论的一个完善和补充。

The second part, the inexistence of limit cycle around o(0,0) about the singularity of the system is perfectly studied with limit cycle theory.

第二部分，运用极限环理论，对系统的奇点o(0，0)外围的极限环的不存在性进行了较完整的分析。

We obtain that:the system has no limit cycle around o(0,0) with the time when o(0,0) is two order of fine focus.we also get some conclusions of inexistence.

得到o(0，0)为二阶细焦点时系统不存在极限环；并且得到了系统不存在极限环的一些条件。

Experimental results show that the equivalence ratio f has a significant effect on the intensity of thermoacoustic instability. In order to sustain the combustion in the Rijke combustor, the inferior and superior limit of the equivalent ratio was 0.63 and 1.75 separately.

试验发现，化学当量比f 对Rijke预混燃烧器内热声不稳定的强度有重要的影响，维持Rijke预混燃烧器持续燃烧的下限极限化学当量比和上限极限化学当量比分别为0.63和1.75。

The calcalus learns is a mathematic branch connected closely with scientific application.Infinitesimal is an important componant in the theoretical system and has an outstanding effect on the forming of the basis and conception of the theory. infinitesimal ; calculus ; the calculus learns ; differential calculus ; integral calculus

引 言微积分学是建立在实数、函数和极限理论基础上，研究函数微分、积分以及有关概念与应用的数学分支。17世纪精密科学的飞速发展，天文学、力学、光学、工业技术要求数学彻底革新，导致了无穷小概念的问世，促使费马增量理论开创微分学的先河，同时奠定了柯西的极限理论。
