MethodA permittivity sensor developed in a previous study was used in laboratory to measure the frequency-response data(gain and phase) of 14 biodiesel/diesel blends(0,5%,10%,15%,20%,25%,30%,40%,50%,60%,70%,80%,90%,100%). Correlation between mixratio and frequency-response was analyzed.
方法采用自行设计的一种介电特性传感器,在实验室测量14种混合比(0,5%,10%,15%,20%,25%,30%,40%,50%,60%,70%,80%,90%和100%)的生物柴油与柴油混合燃料的频率响应特性(振幅增益和相位差),分析频率响应特性与混合比的相关性,并用PLS和Stepwise回归法进行拟合,建立混合比的检测模型。

Permittivity
- abstract: In electromagnetism, absolute permittivity is the measure of the resistance that is encountered when forming an electric field in a medium. In other words, permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium.

In addition to that, we have that epsilon nought value, remember that's the permittivity constant in a vacuum, and basically that is what we use as a conversion factor to get from units. We don't want namely coulombs to units, we want that will allow us to cancel out in this equation.
这是电子的电荷，此外，我们有epsilon零，记住这是真空的介电常数，这是我们用来转换单位的转换常数,我们不想用库伦单位，我们希望这个可以在方程中约去它。
