The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

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.

In the paper only the range of normal value and the description of frequency distribution are discussed. In theory the widely-used percentile method to determine the range of normal value is imperfected. Curve fitting method show some advantage in determining the range of normal value, but is difficult to calculate.
从理论上说明了现在常用的确定正常值范围的方法存在一定的问题,尤其证明了大家使用得比较多的百分位数法存在的缺陷,说明了曲线拟合法的优点,而在频数分布拟合完成之后,就已经找到了频数分布资料的理论分布曲线,有了理论分布函数,我们利用分布函数计算正常值范围就比较容易,也比较准确。
