Particularly, the dynamics of soliton periodic distributed amplification system is discussed in detail.

Notes on period distribution for two classes hamming codes;

The calculation formulae for period distribution of q-ary BCH codes with designed distance 7 were obtained based on the discussion of cyclotomic cosets and property of cyclotomic polynomials: the period distribution is q s power.

The period distribution of q-ary BCH codes is studied by some important theory functions and cyclotomic coset,and the number of non-periodic equivalence classes of q-ary BCH codes with design 5 is given.

Antiplane problem of doubly periodic arrays of annular crosssection inclusions;

It is thought that the loose slope itself evolves towards the critical state,and the evolution features present two kinds of different kinetics actions:for uniform-granule loose slope,its large scale avalanches obeying quasi-cycle distribution,for non-uniform-granule loose slope,its avalanches obeying power-law distribution,and arising self-organization criticality .

In this pa-per,we define theλ-period distribution and the generalλ-period dis-tribution of error-correcting codes over finite field Fq on the basis ofprevious work,and show that they have some properties which are anal-ogous in some respects to properties of the period distribution and thegeneral period distribution of error-correcting codes over Fq.
