1.前言温度敏感铁氧体(TSF)作为测量和控制元件是很有用的。它们的居里点范围宽,在居里点以下仍维持它们的铁磁特性。实验发现:(1)TSF 的饱和磁通密度和电阻随温度增加而减少,(2)TSF 属于半导体,类似于热敏电阻,它的湿度和电阻之间存在函数关系,即它的电阻随温度增加而降低;(3)磁阻与温度有关,
1. Introduction Temperature-sensitive ferrites (TSFs) are useful as measurement and control components. Their wide Curie point range maintains their ferromagnetic properties below the Curie point. The experimental results show that: (1) the saturation flux density and resistance of TSF decrease with increasing temperature, (2) TSF belongs to the semiconductor, similar to the thermistor. The relationship between humidity and resistance is as follows: Increase and decrease; (3) reluctance and temperature,
