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.

Essay 2 of this study investigates how background risk affects households' insurance purchasing decision, expenditure share and amounts of insurance by using data of Survey of Family Income and Expenditure in Taiwan. Using the income risk as the proxy for background risk and controlling other wealth and demographic factors, the findings suggest that insurance expenditure is positively affected by uninsurable background risk.

Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth).

根据不同造山带花岗岩的形成背景，地质地球化学特征差异，以阿尔泰，东昆仑，华北燕山，东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系，区分出中国大陆的5种大陆地壳生长方式：阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质，热输入和上地壳混合为主的方式；东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入，改造元古宙造山带基底的方式；东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式；燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式；南岭式燕山期对流地幔输入大陆的是以热为主，物质为辅，大陆地壳生长是以陆壳物质再循环为主的生长方式。

Asymmetric over-introgression of the indica alleles on chromosome 7 and many specific regions on other chromosomes in the japonica genetic background is consistent with the general trend observed in the RIL and F_2 populations of the same cross, suggesting a high genetic load in the japonica gene pool, and japonica genome experienced a very severe bottleneck by artificial domestication.2 Genetic background effect on QTL expression of grain weight and its related traitsGenetic background effect on main-effect QTL and digenic epistatic QTL mapping for GWT and its related traits including GL, GW and GT was dissected by a large set of reciprocal introgression lines and recombinant inbred lines derived from Lemont and Teqing in Beijing environment.

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

There is a brief introduction about the development of western just view in Chapter one, among them it is a key about understanding of the social just concept and value judgment, which create the academic background for the just dispute of Rolls and Nozick, promise that will explain next at the same time; Chapter two in this text should explain emphatically, through the two theory frame exposition and comparative analysis, we can draw the conclusion that the essential of the dispute focuses on the value judgment of social justice, that is to say , it is the understanding to right " question ; It is the investigation of social background aboutthe dispute mainly in Chapter three, this shows , the thinking essences of any social justice are all demanded by the reform to the unreasonable social current situations , and this kind of reform often needs implementing to the system or system aspect, therefore the thinking to the theory needs putting in the specific social environment, only through this can we make the accurate judgment ; Begin from chapter four, it is the practical problem that the full text needs solved, namely the unjust problem existing in the transitional country. By probing into the reference meaning of just ideas between Roils and Nozick, and build up foreshadowing for the system of the last chapter; The last chapter, the corresponding solution has be put forward aimed at the origin of the unjust phenomenon that our society make the transition, namely under the background of system innovation, we should structure the scientific management mode, and realize from "good policy " to the basic " good at managing .

第一章简要的介绍了西方正义观的演变过程，其中关于社会正义概念的理解和价值判断是个关键，同时也是为接下来要阐述的罗尔斯、诺齐克正义观的争论创设一个理论的背景；第二章是本文要着重阐述的环节，通过对两者理论框架的阐述和比较分析，得出两者争论的根本还是社会正义的价值判断上，也就是对于&权利&问题的理解；第三章的设置主要对两者争论的社会背景的考察，由此可以看出，任何社会正义的思考实质都是对不合理的社会现状的改革诉求，而这种改革往往需要落实到体制或制度层面，因而对于理论的思考也需要放在特定的社会环境中，才能做出准确的判断；从第四章开始，是全文需要解决的实际问题，即针对转型国家在转型中存在的非正义问题，探讨罗尔斯、诺齐克正义理念的借鉴意义，并为最后一章的制度架构做铺垫；全文最后一章，针对我国社会转型中的非正义现象的产生根源，提出了相应的解决办法，亦即在制度创新的背景下，构建科学管理模式，实现从&善政&到&善治&的根本转变。

By means of equalizing the histogram, the contrast of original thermal image is enhanced; then image region of the disc surface of insulator is intercepted manually; through the envelope of the smoothened histogram of thermal image the segmentation threshold is extracted and the morphological filtering is applied to the threshold- segmented binarized image to obtain insulator disc surface image and background image, and then 10 infrared image features of insulator disc surface image and background image, such as the highest temperature, the lowest temperature, mean temperature, variance of temperature distribution of both kinds of images, as well as maximum temperature rise and mean temperature rise of insulator disc surface relative to background, are extracted; finally, the good and bad features are discriminated by single factor variance analysis, thus the feature selection is implemented.
