Tóm tắt:Let $\mathbb F_{2}[u]=\mathbb F_{2}+u\mathbb F_{2}$, $u^2=0$. In this seminar, we construct a class of $\mathbb F_{2}[u]\mathbb F_{2}[u] $-additive cyclic codes generated by pairs of polynomials.~We discuss their algebraic structure and show that generator matrices can be obtained for all codes in this class. We study the asymptotic properties of this class of codes by using a Bernoulli random variable. Moreover, let $0 < \delta < 1$ be a real number and $k$ and $l$ be co-prime odd positive integers such that the entropy $h_{2}(\frac{(k+l)\delta}{4})<
