And the mechanism was discussed . the form of the gold electrode was designed so as the reference capacitor cr can correct the non - linearity of the main variable capacitor cp . the characterization on absorbability and erosive - proof to ceramic of gold conductive sol was studied 对金电极的形状进行了设计，设置参照电容cr ，可较好地修正测量电容cp的非线性；研究了金导电浆料的配方、组成，通过调节浆料的成分，加入部分添加剂，提高了烧结后的电极对瓷体的附着力和耐腐蚀性。
