The main contributions of the second part of this dissertation are focused on the cryptographic properties of logical functions over finite field, with the help of the properties of trace functions, and that of p-polynomials, as well as the permutation theory over finite field: The new definition of Chrestenson linear spectrum is given and the relation between the new Chrestenson linear spectrum and the Chrestenson cyclic spectrum is presented, followed by the inverse formula of logical function over finite field; The distribution for linear structures of the logical functions over finite field is discussed and the complete construction of logical functions taking on all vectors as linear structures is suggested, which leads to the conception of the extended affine functions over finite field, whose cryptographic properties is similar to that of the affine functions over field GF (2) and prime field F〓; The relationship between the degeneration of logical functions and the linear structures, the degeneration of logical functions and the support of Chrestenson spectrum, as well as the relation between the nonlinearity and the linear structures are discussed; Using the relation of the logical functions over finite field and the vector logical functions over its prime field, we reveal the relationship between the perfect nonlinear functions over finite field and the vector generalized Bent functions over its prime field; The existence or not of the perfect nonlinear functions with any variables over any finite fields is offered, and some methods are proposed to construct the perfect nonlinear functions by using the balanced p-polynomials over finite field.

本发明涉及一种时频资源的分配方法，所述方法包括：把一个长度为L的序列{x，i＝0，1，2，…L-1}中的每一点作为一个k次多项式的自变量，改变多项式的系数生成多个长度为L的序列{f}，其中k是非负整数，多项式中的运算在伽罗华域GF中进行，其中Q＝p m ，p是一个素数，m是非负整数；把生成的序列分配给多个小区，生成各小区的偏置序列集合，其中分配给同一个小区的序列所对应的生成多项式的常数项不同，其他项的系数都相同；由所述小区的偏置序列生成对应的时频图案单元，将时频图案单元经过频域等间隔重复，得到完整的时频图案。

The SDB eclogites, on the other hand, were strongly overprinted by a high-pressure granulite-facies metamorphism under conditions of p=1.9~2.0 GPa and T=873~948℃, followed by temperature and pressure decrease to the amphibolite-facies. The process of temperature increase with decreasing pressure from UHP eclogite to high-pressure granulite suggests that the SDB eclogites exhumed at low speed and underwent strong thermal relaxation at a level of crust-mantle transition or thickened lower crust.

It read:'Woody Allen says he ate at a restaurant that had O.P.S. prices—over people's salaries.' Dreadful by any standards, and thus ideal for the likes of Winchell, Ed Sullivan and Earl Wilson, whose columns ate up more material than the gypsy moth caterpillar.

上面写着：'伍迪艾伦说他曾在O.P.S价位的酒店吃饭。O.P.S-- over people's salaries' 他的专栏博采众家之长，揉进各种由于摒弃种种写作框架，思维方式与Winchell译注1， Ed Sullivan译注2 Earl Wilson译注3相似。
