用AT89S51单片机的P0.0/AD0－P0.7/AD7端口接数码管的a－h端，8位数码管的S1－S8通过74LS138译码器的Y0－Y7来控制选通每个数码管的位选端。AT89S51单片机的P1.0－P1.2控制74LS138的A，B，C端子。在8位数码管上从右向左循环显示“12345678”。能够比较平滑地看到拉幕的效果。

The package contains a Reed-Solomon coding and decoding program, derived partly from Phil Karn/Robert Morelos-Zaragoza "new_rs_erasures.c". In particular the Berlekamp-Massey algorithm has not been modified. New features compared to "new_rs_erasures.c" are: - fully parameterized: code parameters (n,k,m) can be selected via command line options. - decoding optional by Euclid or Belekamp-Massey algorithm - efficient support of shortened codes - extensive verbose levels for hardware verification

This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific code from the higher-level PCI IDE bus driver, much as SCSI minidrivers isolate code from the SCSI port driver. See the Release Notes section for more information. This sample works on both x86 and Alpha platforms, and is 64-bit compliant. It builds with Microsoft® Visual C® 6.0. It does not implement Plug and Play or Power Management.

按照Clifford A . Shaffer《数据结构与算法分析（第二版）》指导，用C#实现的B+树，接口定义良好。最好重写“从文件载入新建树部分”的代码以提高建树效率。实现细节之一：当“需要插入子节点的节点”已满而相邻节点未满时会平分两者节点而不是分裂该节点。
