查询词典 perform functions

This article is focused on the use of Mathematica graphics functions to perform some abstract concept of mathematical analysis, the conclusion of the understanding; auxiliary function for the extreme value; and its application in the series.

With internationally latest studies, the paper also proposes some biquadrate filters which are capable to perform the functions of second-order low pass、 high pass、 band pass、 band stop、 all pass filtering by selecting one of the three inputs or their proper combinations from the same configuration, furthermore whose natural frequency and the quality factor can be tuned independently. Then a continuous-time biquadratic filter using CCCII is proposed, which can be used in hearing aids and in other analog signal processing applications. Lastly a current mode and a voltage mode novel n-order filters of multifunction are presented. Not all both of the n-order filters are electronic tunable,but also they are integrated conveniently and compatible with VLSI technology.

尽量的全面归纳以电流控制传送器为有源器件的有源网络模拟电路、模拟信号处理电路，借鉴国内外最新研究成果，提出两种基于CCCⅡ的双二阶滤波器，这些电路在不需要改变电路结构的情况下，能同时实现低通、高通、带通、带阻或全通多种滤波功能，并且滤波器的特征频率ω_0和品质因数Q可实现独立调节；其中一种基于CCCⅡ的双二阶滤波器，首次提出将CCCⅡ应用于可编程助听器领域；最后设计了两种高阶滤波器，电压模式和电流模式各一种，这两种滤波电路均能实现多种滤波功能，能实现滤波器参数的电调谐，具有易于集成等优点。

The effective distribution of the public land bears the realization of government responsibility, and there is such logicality between them. To realize the responsibility of government needs to perform the governmental functions. Public service is the main part of the transformation of governmental functions. Providing public service should also be based on public land.

有效配置公共用地承载了政府责任的实现，两者之间蕴含着这样的逻辑关系：实现政府责任需要履行政府职能，公共服务是政府职能转型的主要方面，提供公共服务又必须以公共用地为基础。
