defects surface中文什么意思
例句與用法
- According to the results of band structures , the electronic structure characteristic of this defect surface is similar to that of sno surface
由相應(yīng)的電子結(jié)構(gòu)分析結(jié)果可知,該類型缺陷表面存在類似于sno表面的特征。 - The main achievements are as follows : the theory models of defect mfl field are set up ; based on the magnetic dipole model and finite element model , the distribution of defect mfl field is simulated in the dissertation ; the component of flux density ( magnetic filed ) parallel to the surface of pipe is detected by a circumferential array of hall probes ; the factors including defect geometry parameters , defect surface angle and shape , pipe material , field intensity , vehicle velocity , background magnetization , operating pressure and remanent magnetization and so on influence the mfl signal characteristics
采用霍爾元件作為缺陷漏磁檢測傳感器，獲得管道軸截面漏磁場切向分量的漏磁信號；研究了缺陷外形尺寸、缺陷傾角和形狀、管道材質(zhì)和磁化強(qiáng)度、檢測儀移動速度、管道背底磁場、管內(nèi)壓力和剩磁對漏磁信號的影響。提出了各通道增益放大、各路漏磁信號偏離調(diào)整、波形微分、數(shù)字濾波和平滑等漏磁信號預(yù)處理方法；分析了等空間采樣的漏磁信號轉(zhuǎn)換為等時間采樣信號的必要性，研究了漏磁信號的小波去噪方法。 - By examining the vacancy formation energy of three kinds of defect sno _ 2 ( 110 ) surface , the most energetically favorable defect surface is that the surface possesses the coexistence of bridging and in - plane oxygen vacancies , which is different with the traditional defect model by only removing bridging oxygen
通過考察形成三種不同類型sno _ 2 ( 110 )缺陷表面的缺陷形成能,結(jié)果表明,形成同時具有橋氧和面氧缺陷的構(gòu)型能量上最為有利,這與通常所認(rèn)為的橋氧缺陷最為穩(wěn)定不同。
