摘　　要：随机序列在现代科学实践中有着重要的作用,但由于其不便于利用,所以引入了伪随机序列的概念.m序列是最早被广泛应用于实践中的伪随机序列,具有良好的随机性和平衡性,但在数量上有着很大的劣势,于是便产生了利用m序列构造的Gold序列.深入研究了伪随机序列的共有性质及m序列和Gold序列的特性,并讨论了伪随机序列在科学实践中的具体应用情况.Random sequence is very important in the practice of modem science,but because of the discommodity in use ,the concept of pseudo-random sequence is introduced. M-sequence is the first pseudo-random sequence that is used in practice, it has favorable randomness and balance, but it has great weakness in quantity, then the Gold-sequence which is based on the m- sequence is engendered. In this paper, the common attributes of the pseudo-random sequences and the respective properties of m-sequence and Gold-sequence are thoroughly researched. The concrete application of the pseudo-random sequence in the practice of modem science is discussed.
