The various functions inside the virtual spectrum analyzer introduced in the paper is time domain wave analysis, fft transfer, ifft transfer, cross analysis, and so on, which are all described in function controls. finally, this paper introduce the assemble of intelligent controls - oriented virtual instrument. and use classical signals and industrial practices to demostrate the accurate of virtual spectrum analyzer
本文介紹的智能控制項化頻譜分析儀所具備的功能，有信號的時域分析、 fft變換以及ifft反變換、信號的微積分運算、信號的頻譜分析、信號自功率譜密度函數計算、信號互功率譜密度函數計算、頻率響應函數計算和相干函數計算，都是集成在功能控制項裏面的。 -
When the analyzer was located in four angles, a photoelectric detector was used to gather the energy of laser, so we can calculate the retardation of wave plate with the phase shifting
測量裝置採用了步進電機帶動檢偏器旋轉，運用光柵編碼器測角裝置測量檢偏器的轉動角度，使用光電探測器採集檢偏器在四個方位角度的光強值，根據移相演算法得出波片的相位延遲角。 -
We also discuss the design of cavity that is used in experiment 、 means for how to stir electromagnetic wave and choice of diameter / length ratio for cavity. final, we have made an experiment to cigarette with apparatus made up of vector network analyzer ( vna ) and cavity that is designed by ourselves, regressed the equation with matlab software, analyzed measurement errors, put forward some means that reduce measuring error
最後，使用自己設計的諧振腔和矢量網路分析儀搭成的實驗裝置對卷煙進行了密度測量實驗研究，並用matlab軟體對測量數據進行了回歸擬合，建立了密度測量的方程，並對測量誤差作了分析，提出了進一步減小誤差的途徑。 -
In analysis and transaction of signals, spectrum analyzer is a classical and important instrument which is mainly used to analyze the time domain wave, amplitude, spectrum domain wave, demodulating analysis, digital filtering, correlate analysis, transfer function and coherence function of signals
