有理函数域 meaning in Chinese

field of rational functions
rational function field

And we know by study , so long as system is controllable and observable at the structure ( over the field f ( z ) of the rational functions in multi - parameters ) , it is always controllable and observable over the field r of real numbers
通过研究我们知道，一个系统只要在结构上(多元有理函数域( f ( z ) )上)是能控能观的，则意味着实数域上该系统实际上总是能控能观的。
