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(xiàn)資料,評(píng)述了熒光光度法測(cè)定亞硝酸根的研究進(jìn)展,包括指示反應(yīng)體系、線(xiàn)性范圍、檢出限、應(yīng)用對(duì)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(dá)( sar )成像算法方面的一些問(wèn)題,主要討論了三種成像算法經(jīng)典range - doppler算法,線(xiàn)性range - doppler算法以及改進(jìn)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(hào)特點(diǎn)使得有利于直接在時(shí)域?qū)夭ㄐ盘?hào)的線(xiàn)性距離走動(dòng)項(xiàng)進(jìn)行校正,針對(duì)這一特點(diǎn)本文討論了線(xiàn)性range - doppler算法的原理及流程,并對(duì)此算法進(jìn)行了仿真分析。
