Based on the approximate estimation of wetted front edge of one dimension soil column , the design parameters of sdi were determined primarily 粘壤土濕潤鋒運(yùn)移速度明顯慢于沙土,特別是容重較大時(shí)更為明顯。
On the estimation of signal & bimodal noise parameters , some foreigners give out approximate estimation , which is applicable only on some condition ; we give out the precise estimation 對于雙模噪聲與信號參量的估計(jì),國外給出了近似估計(jì),只在一定條件下適用:本文給出了精確估計(jì)。
As for the design of alloy system and the determination of the quantity of main contents , they rely on the approximate estimation after simply calculation , which result in longer development cycle , higher cost and worse accuracy 在合金系統(tǒng)的設(shè)計(jì)和某些主要成分的用量上,輔以簡單計(jì)算進(jìn)行粗估,設(shè)計(jì)周期長、開發(fā)成本高。因此,焊材設(shè)計(jì)手段的更新至關(guān)重要。
In order to decrease the computational complexity of higher - order statistics ( hos ) , novel approximate estimation theorems of the foc and the fifth order cumulants are created and proved in theory . the simulation result shows that employing the estimation theorems to optimize the calculation of higher order statistics is an effective method 理論分析與仿真表明:按估計(jì)定理對高階統(tǒng)計(jì)量的計(jì)算進(jìn)行優(yōu)化,不僅計(jì)算量能大幅度地減小,而且保證了通過估計(jì)得到的高階累積量有抑制高斯噪聲的優(yōu)越性能,這為高階統(tǒng)計(jì)量的工程應(yīng)用創(chuàng)造了一條捷徑。
