查询词典 data information

Nowadays the researches of frequency distribution of data are almost limited to normal distribution, while other distributions are seldom studied. Many frequency distributions of data are not normal. This kinds of frequency distribution of data widely exist. Unimodal frequency distribution of data often occurs.

现在绝大多数关于频数资料分布的研究都是基于正态分布的，而对其他类型的分布研究得比较少，实际上频数分布在许多情况下并非呈现正态分布，分布的形态丰富多彩，很多资料都是呈现单峰分布，本研究就是利用数学上常见的八种连续型变量的分布类型去拟合单峰频数资料。

Finally, from the view point of recording high-fidelity data page, we optimized the storage system by using beam shaper in signal beam, and redesigning geometry to increase the uniformity of reference beam. In the final demonstration experiment, we encode 10KB Flash to four data pages, each including 512×512 bits. The data pages are 1:2 pixels matched. These four data pages were stored in a single point in a photopolymer media of Aprilis Corporation by using angle multiplexing method, and successfully retrieved.

根据我们设计的串行二进制数字数据与数据页之间的编解码方法，将一段10KB大小的Flash视频编码为4幅512×512幅面，1：2匹配的数据页，并成功的在美国Aprilis公司光致聚合物材料中完成了这4幅数据页的单点角度复用存储，再现数据页经过偏移补偿算法和PMSF算法处理后的平均原始误码率为2.4×10-4，这样低的误码率完全满足后期软解码的需要，并使得解码后的数据可以满足用户误码率的要求。
