Conclusion Norm of operator is very important to estimate the spectral radius of operator.
结论算子范数对于估计有界线性算子乘积与和的谱半径是至关重要的。

In this chapter, we give some operator inequalities and norm inequalities by means of spectral decomposition and functional calculus.
在第二章中，作者以谱分解、函数演算等为工具，给出一些重要的算子不等式与范数不等式。

The cavity pyroelectric detector is usually used as the work norm to calibrate relative spectral responsivity of detectors because of its flat spectral responsivity in broad spectra range.
