求翻译：把最优资本结构定为一个“点”是不尽合理的，在很大程度上削弱了理论研究本身的实际指导价值。最优资本结构在理论上是可能存在的，但现实中却难以确定。从可操作性来说，企业最佳资本结构应该是某一个区间范围，这样会更富有现实和指导意义。试图在理论上研究出一个最佳资本结构点只能是理论上的假设，不能说这种研究是徒劳的，但可以说无实际意义。理论研究的主要目的不仅是给实践一个具体结论，更应该是指明具体的思维方式和途径。是什么意思？

Optimal capital structure as a "point" is unreasonable, which greatly reduced the theoretical study of the actual guidance value. Optimal capital structure is possible in theory, but in reality it is hard to determine. Operability of an optimal capital structure should be the scope of a certain inte
