    • A computing system generates and displays a comparison task list that reports differences between a source task list for a project and a modified task list for the project. The comparison task list may enable a user to determine the implications of changes to the project by providing a comparison of the source task list and the modified task list. The computing system generates the comparison task list by generating the comparison task list as a copy of the source task list. The computing system automatically adds each task item in the modified task list that does not have an equivalent task item in the comparison task list to the comparison task list at positions that depend on whether the task items have previously-processed sibling task items in the modified task list. When the computing system has processed each task item in the modified task list, the computing system displays the comparison task list.
    • 计算系统生成并显示比较任务列表,该列表报告项目的源任务列表和项目的修改的任务列表之间的差异。 比较任务列表可以使用户通过提供源任务列表和修改的任务列表的比较来确定对项目的改变的影响。 计算系统通过生成比较任务列表作为源任务列表的副本来生成比较任务列表。 计算系统自动将修改的任务列表中的每个任务项目添加到比较任务列表中没有等效任务项目的任务项目到依赖于任务项目是否已经修改过的同级任务项目的位置的比较任务列表 任务列表。 当计算系统处理修改的任务列表中的每个任务项目时,计算系统显示比较任务列表。

    • Disclosed is a dispersion compensating optical fiber that includes a core surrounded by a cladding layer of refractive index nCL. The core includes at least three radially adjacent regions, a central core region, a moat region having a refractive index nM that is sufficiently lower than nCL such that &Dgr;M≦−0.4%, and a ring region. As the ring region exhibits sufficiently high refractive index at a sufficiently long distance from the outer edge of the moat region, the fiber can exhibit low values of negative dispersion slope at low values of negative dispersion and yet exhibit good bending loss. This ring region is also capable of imparting to the fiber a relatively high cutoff wavelength, so that the present invention is particularly well suited for use in L-band systems. A particularly suitable fiber has an index profile in which that part of the ring region at the transition between the moat and the ring region has a refractive index such that its delta value is close to zero. Also disclosed is a method of forming the fiber of the present invention.
    • 公开了一种色散补偿光纤,其包括由折射率nCL的包覆层包围的芯。 芯包括至少三个径向相邻的区域,中心芯区域,具有足够低于nCL的折射率nM的护城河区域,使得DELTAM <= -0.4%,以及环形区域。 由于环形区域在距离护城河区域的外边缘足够长的距离处呈现足够高的折射率,所以在低分散负值下,纤维可以表现出低的负色散斜率值,并表现出良好的弯曲损耗。 该环形区域还能够赋予纤维相当高的截止波长,使得本发明特别适用于L波段系统。 特别合适的纤维具有折射率分布,其中在护环和环区之间的转变处的环区的那部分具有折射率使得其δ值接近于零。 还公开了形成本发明的纤维的方法。
