    摘要:

    以蘋(píng)果為試材，進(jìn)行高壓脈沖電場(chǎng)預(yù)處理對(duì)其介電特性影響試驗(yàn)研究,，分析獲得脈沖電壓,、頻率對(duì)介電特性的影響,，并運(yùn)用電磁場(chǎng)理論分析其影響機(jī)理,。結(jié)果表明,，蘋(píng)果的等效電容,、等效阻抗均隨脈沖電壓、脈沖頻率的增大而減??；高壓脈沖電場(chǎng)參數(shù)對(duì)果蔬介電特性有一定影響。

    Abstract:

    Taking apples as experimental materials, effect of pretreatment of high voltage pulsed electric field on dielectric properties was studied. The effect of pulse voltage, frequency on dielectric properties was analyzed. The theory of electromagnetic field was used to analyze the influence mechanism. The results showed that equivalent capacitance and equivalent impedance of apple were both decreased when the pulse voltage and the pulse frequency increased. The parameters of high voltage pulsed electric field had a certain effect on dielectric properties. The obtained conclusion could provide reference for further research on the effect of electrical parameters on dielectric properties for different fruits and vegetables, and also parameters optimization of high voltage pulse electric field pretreatment.
