  1. To act in matters of world metrology, particularly concerning the demand for measurement standards of ever increasing, range and diversity, and the need to demonstrate equivalence between national measurement standards

  2. 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,一個運算元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。
