Abstract
The statistics of intensity data from hemihedrally twinned specimens are analyzed in terms of a new parameter and are shown to take a simple form in both the centrosymmetric and non-centrosymmetric cases. This analysis provides a sensitive method for determining the twinning fraction. The effects of intensity measurement errors on the observed statistics are discussed.
摘要
对半面孪晶样品的强度数据统计进行了新参数分析，并表明在中心对称和非中心对称情况下均呈现简单形式。该分析提供了一种测定孪晶分数的灵敏方法。讨论了强度测量误差对观测统计的影响。
