电解质溶液复介电常数测量中气泡影响的分析

Influence of Air Bubbles on the Measurement of Complex Permittivity of Electrolyte Solution

摘要:

电解质溶液复介电常数的准确测量对于生物电磁学和微波化学等领域是至关重要的,简单而有效的测量方法就是使用开口同轴线。由于电化学反应,插入溶液的测量探头表面容易产生气泡,对测量结果产生影响。文中针对气泡的不同位置和大小对氯化钠溶液复介电常数测量的影响进行了数值分析,计算结果表明,电解质溶液复介电常数测量值的实部受气泡影响很小,而虚部受气泡的位置、大小和个数的影响。
