1．引言如今，数学家经常使用计算机代数系统辅助他们的数学研究；他们做思考，然后把冗长的计算留给计算机．每个人都“知道”计算机比人们能更好地执行这些工作．但是，当然，我们必须相信这些强大的计算机代数系统的计算结果．首先，让我们澄清这篇论文不是以任何方式去比较不同的计算机代数系统，而是作为一个例子，看看当数学家使用这类软件时，他们所期望水平的当前状态．尽管我们的例子是一个特定的软件系统，我们确信类似的情况可能在其它的程序也会发生．

星形胶质细胞是脑内神经胶质细胞中数量最多的一种类型,对脑血管系统具有重要的影响。它们参与调控血管周围内稳态、血脑屏障的完整性、与外周免疫系统的交流、血液中代谢物的转移以及与神经元活动相应的血管收缩。这些调控过程发生在由血管周围星形胶质细胞突起组成的几乎完全覆盖了脑血管特殊界面中。科学家直到最近才开始研究这种界面的形成方式及其如何影响脑血管功能。本文综述了有关星形胶质细胞在调节脑血管系统中作用的文献。涵盖了胶质血管界面的解剖结构和发育、已知的胶质血管功能和分子因素、后者在某些病理生理情况下的作用以及最近开发的用于检验星形胶质细胞在血管界面作用的尖端实验工具。最后,本综述重点介绍了该研究领域中的一些尚未解决的问题。
