摘要
铁磁材料居里温度测量的关键在于利用数据所作图像来确定铁磁材料的居里温度,对无规律的数据值序列如何进行精确处理是其困难之处.利用传统的作图法只能显示出各物理量之间的粗略函数图像,且当数据值序列无明显规律时,作图法无法确定物理量间的函数关系式.此时利用作图法必将导致较大的偶然误差.此外对同一组数据多次利用作图法处理时,将得到误差不同的实验结果.而matlab所提供的强大数据分析计算功能使问题变得精确、简化.应用于铁磁材料的居里温度测量必能提高处理结果的精确度,减少在处理过程中所引入的偶然误差.
The measurement of ferromagnetic materials Curie temperature is the key to the use of image data to determine the Curie temperature of the ferromagnetic materials,the erratic sequence data on how accurate the value of its deal with difficulties.The use of traditional mapping shows that only the physical function between the rough image,and the value of the sequence data when no law,no mapping function to determine the relationship between the physical style.At this point the use of mapping is bound to lead ...
