中文摘要：
采用了PC68数字高阻计和WE-100型液压万能试验机，研究了甲基四氢邻苯二甲酸酐（Methpa）用量对环氧树脂E-51绝缘灌注胶电阻率和抗压强度的影响，并采用红外光谱（FTIR）对不同配比的共混物的固化程度进行定量分析，进一步探讨其影响机理。结果表明：当Methpa用量为70phr时，由于环氧树脂绝缘灌注胶的固化度达到99％，电阻率（体积电阻率1．78×10^16Ω·cm，表面电阻率8．55×10^15Ω）和抗压强度（113．45MPa）达到最大。
英文摘要：
The effect of anhydride amount on the resistivity and compressive strength of epoxy resin pouring sealant was investigated by using PC68 digital high resistance meter and WE - 100 hydraulic universal testing machine, and dif- ferent proportions of the blends about curing degree were investigated by using FFIR. The result showed that when the a- mount of anhydride was under 70 phr, the cured 1.78 ×10^16Ω·cm, surface resistivity 8.55 × 10^15Ω product of the curing degree was 99%, resistivity （volume resistivity and compressive strength（ 113.45 MPa） reached the maximum
