frequency curve [经] 频率曲线
- The substantial difference lies in that guaranteed rate frequency method determines the rate artificially, but synthetic duration curve method has its intrinsic frequency
其根本差别只在于保证率频率法是人为地确定频率,而综合历时曲线法本身固有一个频率。 - In this paper we idealized the characteristic curve of transistor, introduced brokenline analysis for the nonlinear state of high frequency power amplifier and analysed its main performance index.
将晶体管特性曲线理想化,对高频功率放大器所处的非线性状态,引入折线分析法对其主要的性能指标进行分析研究.给出了高频功放非线性状态下的输出功率、率、散功率等物理量.简化了非线性状态下高频功率放大器的分析. - The optimum frequency for corrosion inspection is found out, the relation between corrosion and lift-off curve is defined, automatic inspection can be done by using microcomputer data collecting sy
通过实验确定了最佳的检测频率,建立了锈蚀程度与提离曲线之间的关系,利用微机数据采集系统实现锈蚀的自动检测。
