Back cone

Analysis of back cone of gears

直齿圆锥齿轮背锥齿形的分析

It can be concluded from these results that the back cone , from which 97 % scattering exposure comes , is the primary scattering source and the key component which makes the spatial distribution of scattering exposure nonuniformity 58 % .

结果表明：后锥是照射量散射成分的主要来源，后锥照射量占总散射量97%；后锥也是造成散射的空间分布不均匀的主要器件，这一不均匀性高达58%。

Research on Filling Materials in Back Boards of Gyratory Cone Crusher

旋回、圆锥破碎机衬板充填物的研究

Howard : Hey , I didn 't see you giving back your Snoopy snow cone maker .

霍华德：喂，我也没看到你把他送你的史努比刨冰机还给他啊！

While the back transitional section puts influence mainly on the decline portion of waveform , it makes decline portion of waveform produce much more distortion along with the increase of the back cone angle .

后过渡段主要对场波形的衰减部分产生影响，使场波形的衰减部分随着后锥角的增大而产生严重畸变。
