The solid immersion lens can be used into an optical storage system It provides the high NA of the system and uses the evanescent wave to produce extremely small optical spots Two proposals about a SIL are given out here The first one is that the protecting layer of the recording layer can be used as one part of the hemi spherical SIL So the recording layer is not polluted The second one is that a SIL can be used at same time in a double layers storage The first recording layer is used a...

固体浸没透镜用于光存储光学系统增大了光学头物镜的数值孔径，利用近场倏逝波读写，减小了光斑的直径，提高了存储密度。文中建议：(1)将半球SIL分割成两部分，其中一部分由存储媒质的保护层充当，避免直接污染记录层；(2 )在半球SIL单层读写的基础上，再将第一层记录媒质作为SIL的一部分形成超半球齐明SIL ，以实现双层存储。并对此时的近场进行了解析分折

Not considering the restriction of the depot s transporting ability in the existing achievement of emergency dispatch, consequently, this chapter establishes a sole-resource optimized dispatch model aimed at "the shortest dispatch time" which includes the constraint of transporting ability under time restriction firstly. Moreover, the chapter deduces the algorithm of the model by mathematical induction step by step. Secondl y, it simplifies the former model and gives a simpler sole-objective model and corresponding algorithm including the constraint of transporting ability. At last, on the basis of the improved model, this chapter discusses a two-phase programming model and a multi-objective programming model which are aimed at "the shortest dispatch time" and "the fewest number of mobilized depots" including the constraint of transporting ability under time restriction.

由于现有应急调运的研究成果中没有考虑到各物资供应点受运输能力的约束，因此本章首先建立限制期内以"应急调运时间最短"为目标且含有运输能力约束的单物资调运优化模型：并利用逐步递推法推导出具体的求解算法；然后，进一步地将此模型及算法进行简化，建立更加简单的含有运输能力约束的单目标优化模型：并且讨论其算法；最后，在改进的优化模型的基础上，讨论限制期内含有运输能力约束且以"调运时间最短"、"出动的供应点数目最少"为目标的双层规划及多目标规划的优化模型及解法。
