Surface radiation characteristics at ny - lesundover the arctic tundra area 北極苔原新奧爾松地區(qū)的地表輻射特征
In light of the generation mechanism , the surface radiation noise can be further divided into the combustion noise and the mechanical noise 按照產(chǎn)生的機(jī)理,柴油機(jī)表面輻射噪聲又可以分為燃燒噪聲和機(jī)械噪聲。
The results show good performance between vis , irl , sun zenith and net surface radiation . the correlation coefficient is up to 0 . 8259 通過理論部分推導(dǎo)出的關(guān)系可以看出:地面凈輻射與太陽天頂角、地面及云面反照率等因子有關(guān)。
As one source of environmental pollution , diesel noise comprises multiple sound sources , which are mainly the aerodynamic noise and the surface radiation noise 柴油機(jī)組噪聲是一種環(huán)境污染源。它由多種聲源構(gòu)成的,主要為空氣動(dòng)力噪聲和表面輻射噪聲。
The dgeu noise is made up of multiple sound sources . in light of the noise radiation mode , it can be classified into the aerodynamic noise and the surface radiation noise 柴油機(jī)噪聲是一個(gè)由多種聲源構(gòu)成的復(fù)雜聲源,按照噪聲輻射方式,柴油機(jī)噪聲可以分為空氣動(dòng)力噪聲和表面輻射噪聲。
