According to the functions and characteristics into linear characteristics, characteristics and paraboliccharacteristic percentage of three.
按其功能和特性分为线性特性，等百分比特性及抛物线特性三种。
2
The releasing characteristic of soil phosphorus can be exactly depicted by parabolic diffusion equation.
抛物线扩散公式能很好地拟和土壤磷素释放特征。
3
The basic factors affecting collimating characteristic are off-axis magnitude, effective aperture and emission position on the focal plane of off-axis parabolic mirror.
