The ability of the ionosphere to reflect these waves is dependent upon normal variations in the electron density at different levels . 電離層反射電波的能力取決于不同高度上電子密度的正常差別。
It presents images of electron density distribution inside the object 它可以提供關(guān)于物體內(nèi)部物質(zhì)電子密度分布的圖像信息。
Plasma electron density diagnosis by nomarski interferometer with raman compression cascade system 兩級喇曼壓縮系統(tǒng)配偏振干涉儀診斷等離子體電子密度
This thesis first stduies electron density imaging based on compton scattering energy spectral data 本文從康普頓散射的能譜出發(fā),研究物質(zhì)電子密度圖像的重建問題。
We obtained holographic interferogram , from which we got the space distribution of plasma electron density by abel inversion 由全息干涉條紋圖樣求解等離子體電子密度空間分布要用到abel變換。
Finally , we can get a curve of electron density changing with the time or the position . this is the result required of system 并最終得到了系統(tǒng)所要求的電子密度隨時間t或隨位置x / d的變化曲線。
Electron density is one of basic parameters of laser - produced plasma , so it has a important role in diagnosis of laser - produced plasma 電子密度是激光等離子體最重要的基本參數(shù)之一,因此在激光等離子體診斷中占有重要位置。
In the third group , the electron density of corneal collagen fibres were uneven with dilated and low electron - densed interfibral spaces 第二組中,角膜膠原纖維排列規(guī)則、連續(xù),電子密度均勻,纖維間可見散在擴大的空隙,呈低電子密度灶。
Then , an implicit expression for electron density and a closed form of threshold voltage are presented fully comprising quantum mechanical ( qm ) effects 給出了電子密度的隱式表達式和閾電壓的顯式表達式,它們都充分考慮了量子力學(xué)效應(yīng)。
The analytical solutions to 1d schr ? dinger equation ( in depth direction ) in double - gate ( dg ) mosfets are derived to calculate electron density and threshold voltage 摘要推導(dǎo)了雙柵mosfet器件在深度方向上薛定諤方程的解析解以求得電子密度和閾電壓。
