实验题目设计和实现关于内存管理的内存布局初始化及内存申请分配、内存回收等基本功能操作函数，尝试对用256MB的内存空间进行动态分区方式模拟管理。内存分配的基本单位为1KB，同时要求支持至少两种分配策略，并进行测试和对不同分配策略的性能展开比较评估。最佳适应算法（Best Fit）： 　　它从全部空闲区中找出能满足作业要求的、且大小最小的空闲分区，这种方法能使碎片尽量小。为适应此算法，空闲分区表（空闲区链）中的空闲分区要按从小到大进行排序，自表头开始查找到第一个满足要求的自由分区分配。该算法保留大的空闲区，但造成许多小的空闲区。因为它要不断地找出能满足作业要求的、且大小最小的空闲分区，所

风速预测对风电场和电力系统的运行都具有重要意义。对风速进行比较准确的预测，可以有效地减轻或避免风电场对电力系统的不利影响，同时提高风电场在电力市场中的竞争能力。基于时间序列法和神经网络法，该文对风速预测进行了研究，提出了预测风速的时序神经网络法。该方法用时间序列法建模，得到风速特性的基本参数，并用这些参数选择神经网络的输入变量；为了提高预测精度，提出了滚动式权值调整手段。该方法有效地提高了风速预测的精度。
