Furthermore, the formulae of transmitted power, loss power, attenuation constant and equivalent impedance for TM and te modes are deduced.

此外，推导出波导tm、TE模的传输功率、损耗功率、衰减常数、等效阻抗等特征参数的边界元公式。

Therefore, there is a perfect compromise between attenuation in stopband and group delay or loss variation in passband.

因此，它在带外衰减与带内幅度特性和带内群时延特性之间有了一个较好的折中。

The lesioninvolves the lateral wall of the sphenoid sinus extending into the rightorbital apex, as demonstrated by loss of normal fat attenuation in thislocation.

此病变累及蝶窦外侧壁，侵入右侧眶尖，表现为此处正常脂肪消失。
