The result of the research on children's learning profile was found that the observation record that derived from teaching process and interview analysis that got from two text-based tests. The students who are high and intermediate achievers can make first-order and second-order conditions on four-type regular problems by means of discussion and presentation in class. In addition, they can solve problems utilizing "perceptibility" when doing two text-based tests.

To begin with, theory of FCSR and its sequence is summarized and investigated. Furthermore, emphasis is placed on the vaule of 2-adic complexity. A conclusion is drawn that the vaule lies in the relation between 2-adic complexity and lineai complexity of a same seqence. Fact that there exists sequence with high linear complexity but low 2-adic complexity is given and analyzed. The value of 2-adic complexity in cryptanalysis can be directly drawn from the very fact. A series of problems are opened based on the value and discussions are done in various depth. Some good results are obtained in these problems such as the 2-adic complexity distribution of periodic sequences and the stability of 2-adic complexity. The value of FCSR in stream cipher design is discussed at the same time.

首先对FCSR及其序列理论进行了系统的总结和研究，然后重点探讨了2-adic复杂度的流密码意义，通过论证表明，存在线性复杂度较大而2-adic复杂度较小的序列类，从而明确了2-adic复杂度的流密码分析意义，进而提出了一系列相关的研究问题并进行了不同深度的探讨，对其中周期序列的2-adic复杂度分布和2-adic复杂度的稳定性等问题得到了较好的结果；同时对FCSR的流密码设计意义进行了探讨，对其中的问题给出了一些思路或简单结论。

On the basis of the generalized phase integral approximation and the beam displacement ray mode theory, which are both developed by Chinese acousticians, a fast method for normal modes analyzing including the leaky modes is presented. The application of this method in the coupled mode parabolic equation theory gives an efficient algorithm for both the range dependent problems (CMPE2D) and the three dimensional problems (CMPE3D).

To obtain quadratical convergence, however, strict complementarity condition at the Danskin point was used. The condition is too strict to be satisfied in many practical problems such as discrete semi-infinite minimax problem. Another kind of Newton method for finite minimax problems was presented by E. Polak and, without strict complementarity at the Danskin point, superlinear convergence (of order 3/2) was proven.

Polak等人提出了一种直接求解极大极小问题的二阶收敛的牛顿法，但是为获得二阶收敛速度要求在Danskin点处满足严格互补条件，这个条件太强，很多实际问题尤其是半无限极大极小问题的离散化不满足该条件；他们又给出另外一种牛顿法，在不假设严格互补条件成立的情况下，证明了它的超线性（3/2阶）收敛性。
