最佳适应算法是动态内存分区分配算法的一种。所谓“最佳”是指每次为作业分配内存时，总是把能满足要求、又是最小的空闲分区分配给作业，避免“大材小用”。为了加速寻找，该算法要求将所有的空闲分区按其内容以从小到大的顺序形成一空闲分区链。这样，第一次找到的能满足要求的空闲区，必然是最佳的。-best adaptation algorithm is a dynamic memory allocation through an algorithm. The so-called "best" means the operation of each memory allocation, always meet requirements, and also the smallest area allocated to idle operations, to avoid "a waste of talent." To speed up the search, the algorithm requires that all leisure district according to content from small to large order of the formation of a regional chain idle. So, the first found to meet the requirements of the free zone will be the best.

正交试验设计方法.试验设计是数理统计学的一个重要的分支。多数数理统计方法主要用于分析已经得到的数据，而试验设计却是用于决定数据收集的方法。试验设计方法主要讨论如何合理地安排试验以及试验所得的数据如何分析等。-orthogonal design. Experimental Design mathematical statistics is an important branch. Most mathematical statistics methods have been used to analyze the data and experimental design was used to decide the method of data collection. Experimental design method to discuss how reasonable arrangements for tests and how the data analysis.
