The CSD algorithm is shown to be efficient design method for complex system in parallel, and can search out better design for mixed continuous/discrete system in very reasonable number of system analysis compared to traditional optimization method, and is able to deal with the issue of dynamic design requirements.

并行子空间设计算法不仅有效地实现了并行设计思想，而且与传统的优化算法相比，CSD算法降低飞机系统分析的次数，找到系统全局最优解的概率也较高。另外，它还能成功地解决含有离散/连续混合变量的设计优化问题，以及具有处理工程设计中设计要求动态变化的能力。

Results The behavioral features of the aged learning and memory impaired rats were as follow: 1 There was little change happened to the sample performance. 2 The spatial reference memory had obviously declined. The swimming times of searching the hidden platform in the place discrimination performance, the swimming time in a 40cm annulus at the primary platform place (A40T) and the platform crossings in the probe trial performance were the most suitable indexes for mirroring the spatial reference memory abilities. 3 The spatial working memory had not decreased so clearly.

结果 老年学习记忆损害大鼠的行为学改变特征为：1简单学习记忆任务的学习能力没有明显变化。2空间参考记忆能力明显减退，寻找平台所用的游泳时间，40cm环内游泳时间(A40T)和平台跨越次数是反映老年学习记忆害大鼠空间参考记忆能力的理想指标。3空间工作记忆能力减退不明显。

Utilizing the inclusion relationship between two subsets or subspaces, disjunct matrices with the same number of elements 1 in each row and column were constructed. However, the experimental number of elements was greater than the lower bound of information.

利用子集或子空间之间的包含关系可以构建出分离矩阵，它的每行和每列中元素1的个数分别都一样，但试验总次数即行数明显大于信息下界。

The disk cache is used to keep frequently accessed data in memory to reduce the number of reads and writes to the hard drive.

磁碟快取的作用是将用户频繁存取的资料存放在记忆体中，减少磁碟的读写次数。

In this system, we introduces cluster architecture to provide global and scalable streaming caching proxy service mechanism; We implement streaming media transfer protocol on caching proxy end; We implement layered caching mechanism (global disk caching and memory caching) using dynamic sharing running memory buffer algorithm to support more stable and real-time parallel streams; We implement client request aggregation by means of streaming session sharing to reduce disk I/O and serve more user; We propose single streaming image to support the unify of pre-fetching streaming and caching streaming, which guarantees the proxy streaming of transparency for client; We design and implement streaming pre-fetching mechanism based on packet feedback information to reduce the number of "rebuffering" on client end; We bring forward streaming caching admission control policy fit for streaming caching proxy server to guarantee the QoS of streaming service.

该系统引入集群架构以提供全局的、可扩展的缓存代理服务机制；实现了缓存代理端的流媒体传输协议；采用动态共享运行缓冲区算法实现了分层缓存机制(全局磁盘缓存和内存缓存)以支持更多稳定、实时的并发流；利用流会话共享机制实现了客户请求聚集，从而减少磁盘I/O同时能服务更多的客户；提出了单一流映像，以支持预取流和缓存流的统一，从而保证代理端服务流对客户的完全透明；设计并实现了基于包反馈信息的流数据预取机制，从而减少了客户端的"rebuffering"次数；提出了适合于缓存代理服务器的流缓存准入控制策略，保证了流服务的QoS。

To cope with the greater dispersiveness of random loads, a design criterion of minimum number of sampling for airplane's takeoff-landing is created for the first time in the world.

针对随机载荷存在较大的分散性，建立了最少空测采样次数设计准则，属国际首创。
