R 树， 存取方式的当中最普遍的的用长方形， 是根据区域的启发式优化围绕的长方形在各个内在结点通过运行在一张规范化的试验平台下高度变化的数据， 询问和操作众多的实验， 我们能设计合并联合的优化的R* 树区域， 各个附寄的长方形边际和交叠在目录使用我们规范化的试验床在详尽表现比较，它结果R* 树清楚地胜过现有的R 树变形Guttman’s线性和二次方R 树和R 树的格林变形，R* 树的这优势举行为不同的型询问和操作， 譬如地图覆盖物。 为两个长方形和多维点在所有实验从一个实用观点R* 树是非常有吸引力的由于以下二个原因1 它高效率地支持点和空间数据同时和2 它实施费用比那少许高级其它R 树。-R tree, which forms of access to the most common use of a rectangular shape, which is based on heuristic optimization rectangular inherent in all nodes running on a standardized test platform height data, inquiries and the operation of many experiments, we can design the optimal merging of the joint R* Tree region, judging from the various and overlapping rectangular marginal in the directory using our standardized test bed in a detailed performance comparisons, and it results R* tree clearly better than the existing R-tree deformation Guttman"s linear and quadratic R-tree and R Green Tree deformation, R* Tree of this advantage at different type of inquiry and operation, such as maps cove

使用MFC实现COM组件时，经常节省许多开发时间。例如，使用AppWizard生成的基于MFC的COM dll工程，已经自动的提供了DllRegisterServer功能的实现。然而，却没有自动生成DllUnregisterServer功能。一般情况下，DllUnregisterServer对于程序是不可缺少的，因为一个完整的程序，不仅需要自注册功能，同时也需要自卸载功能。-use MFC COM, we often save many development time. For example, the use of AppWizard generated based on the MFC COM dll, has provided automatic DllRegisterServer functions. However, they did not automatically generate DllUnregisterServer functions. Under normal circumstances, the procedure for DllUnregisterServer is indispensable. because a complete set of procedures, not only from the registration function, but also need to uninstall feature since.

在一个基于RTOS优先级，优先级反转
In a preemptive priority based RTOS, priority inversion
problem is among the major sources of deadline
violations. Priority inheritance protocol is one of the
approaches to reduce priority inversion. Unfortunately,
RTOS like uC/OS can’t support priority inheritance
protocol since it does not allow kernel to have multiple
tasks at the same priority. Although it has different ways
to avoid priority inversion such as priority ceiling
protocol, developers still have some difficulties in
programming real time applications with it. In this paper,
we redesign the uC/OS kernel to provide the ability to
support round robin scheduling and implement priority
inheritance semaphore on the modified kernel. As result,
we port new kernel with priority inheritance semaphore to
evaluation board, and evaluate the execution time of each
of the kernel service as well as verify the operations of
our implementation.-In a preemptive priority based RTOS, priority inversionproble
