BZ：零带

“Band Zero”在学术和科学领域（尤其是物理学中）常被缩写为“BZ”，以便于快速书写和日常使用。该术语的中文译名为“零带”，通常用于描述能带结构中的特定能量区域。

The wavelet coefficients in high frequency sub band distribute near the zero values symmetrically;
高频段小波系数都对称分布在零值附近；
The amplitude of negative frequency components of multiple analytical band pass filter is zero, which can greatly reduce the demand for character of digital filter, increase the maximum multiple of Zoom analysis and improve the accuracy of Zoom spectrum analysis.
复解析滤波器的负频率部分幅值为零，能够大大降低对数字滤波器特性的要求，提高细化分析的最大倍数和细化谱分析的精度。
Most optical oscillator strengths for the transitions between valence band and conduction band are nearly equal to zero.
价带顶和导带底附近的带间跃迁振子强度大部分都近乎为零；
As long as the reject band is not equal to zero in transmitting or receiving terminals, signals will produce adjacent frequency leakage.
在通信发射和接收端的滤波器阻带因子非零的情形下，信号会产生邻频泄漏。
