Our aim is to design a filter having high selectivity and constant group-delay within the pass-band and according with the demand of equal pass-band attenuation ripple, to meet the requirements of distortionless transmission of television, facsimile and data signals.
目的在于设计一种具有高选择性,并满足通带衰减等波动要求、通带群时延恒定的滤波器,以适应电视、传真及数字信号等的无畸变传输要求。
the linear relationship of the transport selectivity of the amino acid through the liquid membrane and the lipophilicity constant of amino acid side-chain has been obtained.
获得了氨基酸的迁移效率与其亲脂常数的线性相关性,并藉此测算出了茶氨酸侧链的亲脂常数。
