The result show that the impedance of amorphous strips increase with frequency,and sensitively decrease with stress increase,especially in the frequency range from 1～100MHz.
结果表明,非晶带的阻抗随着频率的增加而增加,并随压力的增加变化更加敏感,尤其是频率在1~100MHz范围内时。
The change in crystalline band can be decided according to the peak shift.
结果表明:傅里叶变换显微红外光谱技术可以方便的测定PET单纤维的红外光谱,且从峰的偏移可以判断结晶带的变化;PET纤维随着拉伸倍数的提高,其取向度和结晶度都相应提高。
Surface corrugation law of amorphous ribbon,consisting of plane and groove was observed and analyzed,and its frequency order is 1×104/sSurface quality depends on the roughness of plane and groove and the difference between the two and ratio of width
观察分析了非晶带表面由平纹、沟纹组成的波纹规律，其频率数量级为１×１０４次／ｓ，平纹和沟纹本身的粗糙度、粗糙度的差值及二者宽度比决定着表面质量。
7)Si_(12)B_(18)amorphous ribbons was carried out using rectangular pulse current.
7)Si_(12)B_(18)非晶带进行退火处理,研究了退火电流密度对非晶带巨磁阻抗效应的影响,同时研究了激励电流频率对退火处理后的非晶带巨磁阻抗效应的影响。
