| 摘 要： | 本文给出一个带有重原子校正项的正切式:用这个公式修正含重原子晶体的结构因子相位可以避免所谓平方效应,从而提高直接法用于测定含重原子晶体的效能。实际试验表明,带校正项的正切式明显地优于通常的正切式,而且能够解决用通常正切式无法解决的对映双解问题。关键词：

| Abstract: | A modified tangent formular taking account of the presence of heavy atoms is given in this paper. It is of the form:The modified tangent formular has the advantage of being able to eliminate the squaring effect. Practical examination shows that it is superior to the conventional tangent formular and can resolve the ambiguity due to the coexistence of both enan-tiomorphs. |
