    摘要： A method and device for storing and reading/writing a composite document are disclosed. The method includes: an initial storing area is pre-allocated for an inner controlling stream of the composite document and the initial storing area is continuous sectors or sector clusters; the inner controlling stream is stored in the initial storing area. The patches of a user data stream and the inner controlling stream in the composite document are reduced using the method or device. Correspondingly, pre-allocating storing area makes the probability of continuously storing the user data stream and the inner controlling stream in the composite document increased. The I/O can be optimized by introducing a strategy of reading cache and writing in a batch size, which can improve the efficiency of reading and writing.

    摘要： A method of forming an array of nanostructures includes forming a plurality of seed points on a surface of a substrate, and growing masks from the seed points to create masked regions of the substrate underlying the masks. A remainder of the substrate comprises an unmasked region. Each mask and masked region increase in size with growth time while the unmasked region of the substrate decreases in size. During the growing, the unmasked region is etched to remove material from the substrate in a depth direction, and, simultaneously, unetched structures are formed from the masked regions of the substrate underlying the masks. Each of the unetched structures has a lateral size that increases with depth.
