Because the basic probability function could not be gotten analytically , a fuzzy system replaces it and the fuzzy rules ' consequent parameters are gotten by the least squares method based on sampling data 由于基本可信度函数不能解析获得,用一个模糊系统对其予以等价,模糊规则后件参数由样本数据通过最小二乘法获得。
Based on sample data which may be correlated and have certain ergodic property , a finite element estimator with multi - stage adaptive filters is designed to estimate the associated ( stationary ) density function 摘要基于可能相关并具有某种遍厉性的样本数据,该文设计了一个具有多级自适应滤波器的有限元估计器去估计相应的(平稳)密度函数。
In this paper , a ku band frequency source based on sampling phase lock loop technique is introduced . the vco of the loop is designed using dielectric resonator . the theory and design method is discussed and emphasized on 本文介绍了一个应用取样鉴相和锁相原理制作的微波ku波段频率源(频率合成器) ,其中的压控振荡器部分是用介质谐振器( dr )设计的。
3 ) the new types of photonic devices based on sampled grating : multiple wavelength laser , wavelength multiplexer / demultiplexer , reconfigurable optical add / drop multiplexer , optical fiber sensor , and multiple channels dispersion compensator 3 )取样光栅构成的新型光子学器件:多波长激光器、波分复用解复用器、重构型光分插复用器、光纤传感器及多信道色散补偿器在光纤通信中的应用前景。
Illegal newspapers repeated the thought - provoking phenomenon , based on sample survey and database research , colleges and universities against the inflow of illegal newspaper library phenomenon , illegal press on the definition , impact and response for reflection and to explore three 非法报刊屡禁不止的现象发人深思,基于抽样调查和数据库调研,针对非法报刊流入高校图书馆的现象,就非法报刊的界定、影响与对策三方面进行思考与探讨。
