Morang — A computer program designed to aid in the determinations of crystal morphology

Abstract
A simple Fortran program (MORANG) designed to help in determinations of crystal morphology is described. The program allows not only the calculation of the angles between crystal planes and directions but also the identification of the morphologically important forms according to interplanar spacing. A brief outline of the principles behind the calculations is given along with a description of the program and its operation.

Title of program: MORANG
Catalogue Id: ABFA_v1_0

Nature of problem
It is often necessary to compare measured interfacial angles with calculated interplanar angles in order to determine the morphology of a crystal.

摘要
本文介绍了一款用于辅助晶体形貌测定的简易Fortran程序（MORANG）。该程序不仅可计算晶面与晶向间的夹角，还能依据晶面间距识别形貌学上的重要晶形。本文简述了计算背后的原理，并对该程序及其操作流程进行了说明。

程序名称：MORANG
目录编号：ABFA_v1_0

问题背景
为测定晶体形貌，通常需要将实测的界面角与计算得到的晶面角进行比对。
