At first we get an equivalence characteristic of the numerical range : w ( a ) = jpn ? pn w ( pna en ) . from the definition of the quadratic numerical range , we can see that the quadratic numerical range depend on the space decomposition . from contrast , we can see that the quadratic numerical range gives a better information about the localization of the spectrum than the numerical range , perhaps just because of this , the quadratic numerical range of an operator need not to be convex , and even that the quadratic numerical range of an operator need not connected , then we give a condition under which the quadratic numerical range of an operator is not connected 為了對數值域的本質有更進一步地了解，首先根據toeplitz - hausdorff定理的證明方法，得到了數值域的一個等價刻畫： w ( a ) ： u _ ( p _ n p _ n ) w ( p _ na \| e _ n ) ，接著引入了二次數值域的定義，從二次數值域的定義我們可以看出，一般說來，在不同的空間分解下，一個算子的二次數值域也會截然不同，但是當所給的兩種空間分解有某種關系時，它在這兩種空間分解下的二次數值域是相等的。
