例句與用法

1. The conversion wizard reports parsing errors on . aspx files that could not be parsed
   轉(zhuǎn)換向?qū)?huì)就無法分析的. aspx文件報(bào)告分析錯(cuò)誤。
2. These will result in wrong diagnosis and some superfluous frequency composition , which will puzzle the detection of mechanical vibration . fault feature extracting plays very important role in gearbox fault diagnosing process
   無論哪種局限性的出現(xiàn)，都會(huì)在機(jī)械振動(dòng)信號(hào)的解調(diào)譜中出現(xiàn)無法分析的頻率成分，給分析帶來很大的困難，有時(shí)甚至引起誤診斷。
3. From theoretical analysis , we know the existing demodulation methods have limitations as following : one is that the subtraction of the two signals frequencies will display as the result of demodulation when we demodulate two time - domain adding signals without modulating information ( fault information ) ; the other one is that aliasing phenomenon will occur as a result of getting absolute value , detection or square in the process of generalized demodulation analysis , such phenomenon will result in some superfluous frequency composition on the frequency spectrum , which will puzzle the detec tion of mechanical vibration . if the sampling frequency is selected from a suitable range , the aliasing phenomenon will be avoided ; the last one is that aliasing frequencies will be produced in zoom demodulation analysis because this algorithm cannot employ digital low - pass filtering to avert the folding frequencies of higher harmonics in the process of zoom sub - sampling
   現(xiàn)有的解調(diào)分析方法存在以下三種局限性：將不包括調(diào)制信息(故障信息)的兩時(shí)域相加信號(hào)，也以其頻率之差作為解調(diào)信號(hào)而解出；廣義檢波濾波解調(diào)分析中，由于取絕對(duì)值、檢波或平方過程可能產(chǎn)生混頻效應(yīng)，在解調(diào)譜中表現(xiàn)為無法分析的頻率成分，并由此推導(dǎo)出避免這種混頻現(xiàn)象的采樣頻率的選取范圍，從根本上避免此類誤診斷的產(chǎn)生；幾種細(xì)化解調(diào)分析新算法中，因?yàn)闊o法在細(xì)化分析的選抽時(shí)進(jìn)行數(shù)字低通濾波，有可能會(huì)出現(xiàn)調(diào)制頻率的高次諧波成分發(fā)生頻率混疊而反折到低頻部分的現(xiàn)象。
