A review is given for progress in measuring nitrite by fluorescence spectrophotometry on the basis of the documentary of recent decade , which contains reaction system , linearity range , detection limit and the applied objects , etc 摘要根據(jù)近十年的文獻資料,評述了熒光光度法測定亞硝酸根的研究進展,包括指示反應體系、線性范圍、檢出限、應用對象等。
This paper discusses several questions about imaging algorithms of missile - borne strip sar . mainly it discusses three imaging algorithms ? classical range - doppler algorithm , linearity range - doppler algorithm and improved range - doppler algorithm 本文論述了彈載條帶式合成孔徑雷達( sar )成像算法方面的一些問題,主要討論了三種成像算法經典range - doppler算法,線性range - doppler算法以及改進range - doppler算法。
The signal character of missile - borne strip sar makes in favor of correcting the linearity range walk in time domain . based on the character this paper discusses the theory and processing flow of the linearity range - doppler algorithm , and make simulation to analyzing it 彈載條帶式sar的信號特點使得有利于直接在時域對回波信號的線性距離走動項進行校正,針對這一特點本文討論了線性range - doppler算法的原理及流程,并對此算法進行了仿真分析。
