利用国际紫外探测卫星（IUE）的一些现有LMC数据和IUE第六期获得的大量新观测资料，重新研究了LMC中紫外线消光的特性。主要目标是确定LMC消光特性是否受到区域调制，如果是，则检查变化的类型和范围。在新的IUE观测中，提出了一个未变红的LMC通量标准的大网格，这将消除光谱不匹配效应，这是消光分析中的并发症。观测到8颗新的变红的恒星。总结了节目明星的特性；讨论了消光曲线的生成方法（包括变红星和未变红星的配对准则）；并对曲线本身进行了介绍和讨论。
The properties of ultraviolet extinction in the LMC are reexamined using some of the existing LMC data from the International Ultraviolet Explorer (IUE) satellite and a large number of new observations obtained during the IUE Sixth Episode. The main goal is to determine if the LMC extinction properties are regionally modulated and, if so, to examine the type and range of the variations. Among the new IUE observations presented is a large grid of unreddened LMC flux standards, which will eliminate spectral mismatch effects as complications in the extinction analysis. Eight new reddened stars were observed. The properties of the program stars are summarized; the method for producing the extinction curves (including the criteria for pairing reddened and unreddened stars) is discussed; and the curves themselves are presented and discussed.
