引言 目前,广泛应用的铁磁性艾林瓦型合金,都明显地受磁场的影响。如图1中的曲线B、C所示,由于磁场的存在,艾林瓦特性不再象曲线A那样理想,即使移去磁场,也由于合金已被磁化,仍然不能恢复到原有的特性。因此,用铁磁性合金制成的恒弹性元件(或频率控制元件),不允许置于有磁场存在的仪器仪表装置之中,否则其精度、灵敏度将受到影响。然而艾林瓦型合金广泛地应用
INTRODUCTION Currently, the widely used ferromagnetic Alingwa-type alloys are obviously affected by the magnetic field. As shown by the curves B and C in Fig. 1, due to the existence of a magnetic field, the Irinvaw characteristic is no longer as ideal as the curve A, and even if the magnetic field is removed, the alloy can not be restored to the original characteristic because the alloy has been magnetized. Therefore, the constant elastic element (or frequency control element) made of ferromagnetic alloy is not allowed to be placed in the instrumentation with magnetic field, otherwise its accuracy and sensitivity will be affected. However, Alingwa-type alloys are widely used
