中文名称：带阻滤波器（BEF)英文名称：Band elimination filter。定义1：抑制某一阻带的频率分量，并允许阻带外频率分量通过的滤波器。所属学科：电力（一级学科）；通论（二级学科）定义2：让限定的频带之外的信号分量通过，而对该频带之内的信号分量大大抑制的谐振电路。所属学科：通信科技（一级学科）；通信原理与基本技术（二级学科） 　　BEF在财务上叫盈亏平衡点（Break Even Point,简称BEP）又称零利润点、保本点、盈亏临界点、损益分歧点、收益转折点。通常是指全部销售收入 等于全部成本时（销售收入线与总成本线的交点）的产量。以盈亏平衡点的界限，当销售收入高于盈亏平衡点时企业盈利，反之，企业就亏损。盈亏平衡点可以用销售量来表示，即亏平衡点的销售量；也可以用销售额来表示，即盈亏平衡点的销售额。
