利用Mathcad 数学软件进行物化探数据处理

Mathcad数学软件包是一个功能强大，易学易用的数学运算工具。Mathcad具有强大、方便的绘图功能．丰富的内置函数及分析工具，支持多种数据格式，同时还有一定的程序设计功能。特别是Mathad中对公式采用直观的表达方式，简单明了，不易出错，因此非常适合于公式运算，特别是复杂公式的运算。物化探数据处理具有两个重要的特点：一是数据量大，二是数据处理主要以公式计算为主。利用Mathcad软件可以根据具体情况快速对数据进行处理．并方便地对计算结果可视化。尽管Mathcad的功能非常强大，但该软件易学易用，不需要对软件本身．特别是程序设计方面作太多的研究，很适合物化探生产施工单位中的科技人员使用。这里介绍了Mathcad的一些主要功能特点，然后通过两个例子说明Mathcad数据软件包在物化探数据处理中可能的应用。

THE APPLICATION OF MATHCAD TO GEOPHYSICAL AND GEOCHEMICAL DATA PROCESSING

Mathcad is a powerful mathematical soft ware, which is easy to understand and use. The Mathcad provides powerful and convenient graphing function, variety of build-in function and analysis tools. It supports plenty of data format and at the same time the Mathcad provides programming tool. Especially, the formulas in the Mathcad are shown visually, which reduce to a great extent possible error when key in formulas. Therefore, it is very suitable for formula-computation, especially for complicated formula. On the other hand, geophysical and geochemical data processing can be manipulated and the result be visualiczed conveniently. Although the Mathcad provides a powerful problem-solving environment, it is easy to use, so it is a suitable soft for engineers to manipulate geophysical and geochemical data processing. In this paper a brief introduction of features of Mathcad is given, then two examples are taken to illustrate the possible use of the soft wave in geophysical and geochemical data processing.
