例句與用法
- The new method of direct determination of micro amounts of elements in electrician silicon - steel chips is based on the high performance of pw 2400 x - ray fluorescence spectrometer system and its software . it can correct both the matrix effect and the influence of sample physical status . specimens of steel chips can be determined directly without any pretreatment . the method has high accuracy and precision , the operation is easy and the analysis is fast
報(bào)道了x射線熒光光譜法直接測(cè)定電工硅鋼鋼屑樣品微量元素的新方法，校正了樣品中元素間的基體效應(yīng)影響和校正了鋼屑樣品的不同顆粒結(jié)構(gòu)，不同幾何形態(tài)及不同表面狀態(tài)的影響，使鋼屑樣品可不經(jīng)處理直接測(cè)定，操作簡(jiǎn)便。 - In order to overcome problems arisen from the application of x fluorescence analysis into complex spectrum produced by archaeological ceramic fragments with multi - element , low content and thick ground , we have employed the artificial neural network into the research of x fluorescence archaeology and conducted three kinds of research works . as the first one , we have applied the linear olam network ( optimal linear association memory network ) and the non - linear bp network ( back - propagation network ) respectively to analyze the complex x fluorescence spectrum of archaeological samples , and taken both results of spectrum analysis to compare with each other . the second , the method of pattern recognition of bp network was tentatively used to perform intelligent identification of production places of these archaeological samples
針對(duì)科技考古中對(duì)大量考古陶片進(jìn)行產(chǎn)地研究時(shí)x熒光分析對(duì)多元素、低含量、厚基底考古陶片產(chǎn)生的復(fù)雜譜分析的問(wèn)題，將人工神經(jīng)網(wǎng)絡(luò)引入x熒光考古中，進(jìn)行了三方面的研究工作：一是用線性olam網(wǎng)絡(luò)(最優(yōu)線性聯(lián)想網(wǎng)絡(luò))和非線性bp網(wǎng)絡(luò)(誤差反傳導(dǎo)網(wǎng)絡(luò))分別對(duì)考古樣品的x熒光復(fù)雜譜進(jìn)行解譜，并比較二者的解譜效果；二是用bp網(wǎng)絡(luò)模式識(shí)別方法對(duì)考古樣品的產(chǎn)地進(jìn)行智能識(shí)別；三是為了提高網(wǎng)絡(luò)運(yùn)算的可靠性和減小基體效應(yīng)及電噪聲的干擾和影響，研究并提出了三種網(wǎng)絡(luò)學(xué)習(xí)前的譜數(shù)據(jù)預(yù)處理方法。
