In conclusion, the results of multilevel model analysis showed that the GERD score of resident in Wuhan was relatively higher and had significant difference with that in Guangzhou, however, that in Shanghai, Beijing and Xi\'an had no significant difference compared with that in Guangzhou. That is to say, the prevalence of GERD in Wuhan was relatively higher compared with the other four survey sites; the residents'health status more worse, the GERD score more higher, and the influence of health status on GERD score was also effected by the region difference between Wuhan and Guangzhou; residents lived in rural region with lower education level, worse spirit status were more likely to suffer from GERD; Moreover, those residents who had family history of GI tumors or other GI diseases, some anamneses (such as dyspepsia, gastritis, rheumatic arthritis), and some diseases (such as irritable bowel syndrome and aerophagia) were also more likely to report GERD. However, no significant association was found between GERD and some other factors in this survey, such as sex, age, etc.

总之，多水平模型分析结果显示，与广州相比，上海、北京和西安居民的GERD总评分没有明显的差异，而武汉居民的GERD总评分则相对较高，即表示武汉的GERD发病率在5个调查城市中相对较高；居民的总体健康状况越差，其GERD总评分越高，且其对GERD总评分的影响受到武汉与广州之间地域差异的影响；农村居民、文化程度越低、精神状况越差者更容易患GERD；另外，那些有胃肠道疾病或肿瘤家族史，既往患有胃炎、消化不良、风湿性关节炎，现患有肠易激综合征、吞气症的人，患GERD的可能性更大，而性别、年龄等因素，本研究未发现其与GERD有显著的关系。

The quality of commercial Mei-Gin products are different from each other XVI and shows unsatisfied results. however, In future, possibly, HMF can be applied as a bioactive standard marker for quality control of Mei-Gin. Based on the qualitative and quantitative analysis of HMF, we can establish the model of quality control, and find out facilitative, efficient, and representative chemical fingerprint for commercial Mei-Gin products. Standardizng the Mei-Gin product from the same procedure will bestead the market of plum in Taiwan. Not only advancing the economic value of plum, but also accelerating the competitiveness in marketplace. Establishent of quality control model with HMF as a bioactive standard marker will be crucial issue in the future.

目前在台湾，梅产品还没有一个可以判断品质优的标准，市面上的产品品质也是差齐，在品质管制方面一直无法获得人满意的成果，透过HMF 的定性定分析，可确初步品质管制的模式，为梅产品订出一个简有效且具代表性的化学指纹图，使所有同一产程的产品一致化以及标准化，这将对於梅子产业有相当大的助，仅可以提升梅子的经济价值，并且增加在市场上的竞争，因此用HMF 作为Bioactive standard marker，并且为梅产品建起品质管制模式在未将会是相当重要的研究之一。

Based on the analysis of the current state of research on data deduplication technologies, this paper makes several conclusions as follows: a How to mine data characteristic information in data deduplication has not been completely solved, and how to use data characteristic information to effectively eliminate duplicate data also needs further study; b From the perspective of storage system design, it still needs further study how to introduce proper mechanisms to overcome the reliability limitations of data deduplication techniques and reduce the additional system overheads caused by data deduplication techniques.

通过对重复数据删除技术当前研究现状的分析，得出如下结论：a 重复数据删除中的数据特性挖掘问题还未得到完全解决，如何利用数据特征信息有效地消除重复数据还需要更深入的研究；b 从存储系统设计的角度，如何引入恰当的机制打破重复数据删除技术的可靠性局限并减少重复数据删除技术带来的额外系统开销也是一个需要深入研究的方面。

The compatibility of both Gvirens and B.firmus was researched. The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.

On one hand,the plastic deformation of PA6 is restricted and restrained by glass fiber which can decrease the impact toughness of SGF-PA6;On the other hand,the debonding of fiber/matrix interface and the pulling-out of fiber can consume partial energy,so the impact toughness of SGF-PA6 can be improved.

另一方面，冲击断裂过程中的纤维/基体界面破坏和纤维拔出可吸收一部分能量(在断口分析中很少看到纤维的断裂，所以未考虑纤维断裂的影响)，这有增加复合材料冲击韧性的影响。
