The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.

摘 要：2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查，结果表明，投礁后礁区海域游泳生物的资源密度明显比投礁前高，增加了25.63倍；礁区海域各类资源种类均比投礁前丰富，总种数由投礁前的23种增加至41种，比投礁前增加了0.78倍，其中，蟹类种数增加最多，增加了1.75倍；在本底调查中没有出现的经济种类龙头鱼 Harpodon nehereus 和红星梭子蟹 Portunus sanguinolentus 在跟踪调查中已成为主要优势种；Shannon-Wienver多样性指数在礁区和对比区均比投礁前有所增加。

First, the survey process, including the sampling procedure and design of the survey questionnaire, increases the risk that the survey will collect nonrepresentative data from the survey population, thereby limiting the overall representativeness of the resulting survey data.

首先，调查过程，包括抽样程序和设计的调查问卷，增加了风险，这项调查将收集数据nonrepresentative从调查的人口，从而限制了整体的代表性，由此产生的调查数据。

Isomap is one of the representative techniques of nonlinear dimensionality reduction.It extends classical multidimensional scaling by considering approximate geodesic distance. However,Isomap is sensitive to noise because the approximate geodesic distance is constructed on the basis of Euclidean distance. In this paper,a kernel-induced distance metric defined in the feature space is introduced instead of the Euclidean distance to evaluate the geodesic distance and construct the corresponding neighborhood graph.

采用核方法在特征空间推导出一类异于欧氏距离的新度量，代替等度规特征映射中的对噪声敏感的欧式距离，用新度量构造测地距离和相应的最小近邻图，提高Isomap算法的抗噪声能力。

Apparently, the results is determined extremely by theoretical algorithm. In 147 zinc-finger-containing genes, 50nt identity sequences were extracted. The results hint that 15 genes may related to block evolution. we analyzed the phylogenetic map of these 15 genes by uncorrected distance, Jukes Cantor distance, Tamura distance, Tajima-Nei distance, Jin-Nei distance or Kimura distance correction, but we found no satisfied result according to the block exchange pattern mentioned before. Introducing Bootstrap test to assistant correction, an comparatively perfect map was drown by Neighbor Joining method.

以147个含锌指基因为模板，我们搜索了其中的50nt一致序列作为板块式进化的核心，获得15个相关基因，应用无校正距离、Jukes Cantor校正距离、Tamura校正距离、Tajima-Nei校正距离、Jin-Nei校正距离和Kimura校正距离等分析了他们之间的进化关系，结果与已知的板块交换模式吻合度较差，引入靴带检验对Jukes Cantor校正距离结果进行统计学校正，并重新用Neighbor Joining方法绘制进化图，结果可靠性大大提高。

However, after I came to understand distance education more deeply, I find that network distance continuation education has many advantages. Firstly, it breaks through the limitation of time and distance. It enables the students all over the country to get instructed from those top level teachers, take the most advanced teaching method, and enjoy richer education information resource. Secondly, it profits in extending the teaching scope, providing more education chances and more flexible way of learning, which make it possible to let more people accept education. Thirdly, the modern network distance continuation, which is based on information, offers a good space-time platform for a lifelong learning. At last, the modern network distance continuation makes students to focus on self study, which help them to fully develop their proactivity, intuitivity and creativity. For the four reasons mentioned above, finally, I chose network distance continuation education as the way of my further education.

但是，经过深入了解之后，发现远程网络继续教育是有很多的优势的，第一，它可以突破时空的限制，使全国各地的学生都能接受一流水平教师的教导，接受最先进的教学方法，享有更丰富的教学信息资源；第二，有利于扩大教学规模，提供更多的学习机会和更灵活的学习方式，使更多的人可以接受教育；第三，以基于信息技术的现代远程网络继续教育，为终生学习的实现提供了时空平台，为人们提供更多开展的实施终身学习的机会；第四，现代远程网络继续教育以学习者自学为主，充分发挥学习者自主学习的主动性、积极性及创造性，综合以上四点，我最终选择远程网络继续教育作为我继续学习的途径。
