1.Abstract:（1）字体太乱，单词中有空格（2） FAPRA此名词第一出现时应有“ FAPRA（Flash-aware Page Replacement Algorithm）”说明。
2.introduction : 没有介绍目前page replacement algorithms designed for NAND flash memory.
3.Ralate Work :The least recently used algorithm (LRU) -->LRU(The least recently used algorithm )
4.实验部分写的比较详细，理论阐述比较详细，数学推导比较严谨，结果展示的图表数据结果比较有说服力。
5.公式（1）（4）错位了
This paper provides an efficient page replacement algorithm called FAPRA which is proposed for NAND flash memory in the light of its inherent characteristics.The algorithm is effective to prevent the serious degradation of
page hit ratio, reduce the number of write operations, as well as lower the degree of wear leveling of NAND flash memory. Heoretical of the algorithm explained clearly and the experiment results to evaluate the proposed algorithms in the paper are very detailed. but , thesis writing is not very standardized,such as many separate words with spaces,the first term does not appear in the full name of the professional,in addition, I think it is better to add some introduce other current page replacement algorithms designed for NAND flash memory in the introduction.
(1)Many separate words with spaces especially in the Abstract section
(2)FAPRA should be written as FAPRA（Flash-aware Page Replacement Algorithm）at the first appeared time
(3)Equation (1) and equation (4) format error
(4)It is better to add some introduce other current page replacement algorithms designed for NAND flash memory in the introduction.
(5) Heoretical of the algorithm explained can be more clearly
