Dianci bileiqi, 1994 阐述了直接法、间接法和湿法（活性氧化锌）三种方法生产的氧化性原料的特点，并分别用此三种原料进行了压敏电阻验证试验。结果表明，间接法生产的氧化锌原料用作压敏电阻性能最好，湿法生产的氧化锌原料也可用作压敏电阻原料，而直接法生产的氧化锌原料则不能直接用于压敏电阻原料。考虑到价格性能比及原料的二次加工，湿法生产的氧化锌原料有望得到应用和推广。

Dianci bileiqi, 2017 在对氧化锌压敏电阻的劣化研究中,由于U1mA和Ileakage存在"拐点效应",从而不能够第一时间判断出氧化锌压敏电阻劣化的情况。为此通过实际的冲击平台,研究在不同冲击时间下,氧化锌压敏电阻阀片内部的温度变化情况,主要得出:距离电极较近位置处的变温率较大,远离电极的一端变温率较小,即氧化锌压敏电阻存在极性现象;当变温率出现明显的变化时,压敏电压U1mA和漏电流Ileakage变化处于正常范围内,当压敏电压U1mA和漏电流Ileakage出现明显变化时,氧化锌压敏电阻已经劣化到一定程度,甚至已经完全损坏 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
