另一方面，全局变量是一种可在同一组件内的任一代码片段中使用的变量。

A global variable, on the other hand, is available to be used in any snippet within the same component.

高斯·马尔科夫序列实验表明，该算法较好地实现了全局最优，并有助于克服对初始码书较为敏感的缺点。

The experiments of Gauss Markov sequences show that the algorithm has better achieved the global optimal point and helps overcome the shortcoming of the sensitivity to initial codebook.
