磁组构在地球科学研究中具有广泛的应用.磁化率各向异性椭球形状可以反映丰富的地质信息.目前磁化率各向异性测量仪器所用软件不能以图形的方式直观地反映样品的磁化率椭球形状,其数据以二进制及文本方式存储,以纯文本方式显示,需借助其它数据处理与绘图程序来判别椭球形状.使用Visual Basic.net编程语言计算岩石样品的主磁化率及主方向,再调用Mathematica数学系统软件核心显示磁化率各向异性椭球的三维图形,调用Grapher绘图程序核心显示主方向,测量数据可直接存储到Excel文件中.首次实现了显示磁化率各向异性椭球的三维图形的功能,同时可以显示主方向的二维图形,可以进行从样品坐标系到地理坐标系的转换及手动输入15个方向磁化率数据进行主磁化率与主方向的计算.
磁組構在地毬科學研究中具有廣汎的應用.磁化率各嚮異性橢毬形狀可以反映豐富的地質信息.目前磁化率各嚮異性測量儀器所用軟件不能以圖形的方式直觀地反映樣品的磁化率橢毬形狀,其數據以二進製及文本方式存儲,以純文本方式顯示,需藉助其它數據處理與繪圖程序來判彆橢毬形狀.使用Visual Basic.net編程語言計算巖石樣品的主磁化率及主方嚮,再調用Mathematica數學繫統軟件覈心顯示磁化率各嚮異性橢毬的三維圖形,調用Grapher繪圖程序覈心顯示主方嚮,測量數據可直接存儲到Excel文件中.首次實現瞭顯示磁化率各嚮異性橢毬的三維圖形的功能,同時可以顯示主方嚮的二維圖形,可以進行從樣品坐標繫到地理坐標繫的轉換及手動輸入15箇方嚮磁化率數據進行主磁化率與主方嚮的計算.

Magnetic fabric has extensive applications in geosciences research. The shape of anisotropy of magnetic susceptibility (AMS) ellipsoid in a sample can reflect abundant geological information. AMS ellipsoid can not be intuitively reflected by graphs through software used by AMS measuring instrument at present. Its data were stored in binary and text format and were displayed by plain text. It is difficult to estimate the shape of AMS ellipsoid without help of other data processing and graph drawing software. We use Visual Basic.net programming language to calculate the principal susceptibility and principal directions, to display a 3D graph of AMS ellipsoid by calling kernel of mathematical system software-Mathematica and to display principal directions by calling kernel of graph-drawing software-Grapher. AMS data measured can be directly stored into an Excel file. This is the first time that 3D graph display of AMS ellipsoid is realized and 2D graph of principal direction is displayed at the same time. It is also convenient to transfer data from sample coordinates to geographical coordinates. Furthermore, the principal susceptibility and direction can be calculated with 15 directional susceptibilities manually input.
