We systemically discuss how to uniquely decide an infinite plane homography matrix by using the structure information in scene and how to evaluate a homography matrix which convert affine reconstruction to Euclidean reconstruction by solving absolute conic images.

系统地讨论了如何利用场景中的结构信息，来唯一地确定无穷远平面的单应矩阵，进而由射影重构恢复仿射重构，以及如何通过绝对二次曲线的像求解将仿射重构变换为欧氏重构的单应矩阵。

In the first part, depending on three or more images, the main research work are listed as follows:(1) using SVD decomposition to realize projective reconstruction;(2) realizing camera self-calibration by solving Kruppa's equation;(3) recovering Euclidean reconstruction from projective reconstruction. Depending on only two images, the main researches are:(1) making out infinite plane homography matrix by using scene structure information, then recovering affine reconstruction from projective reconstruction;(2) making out the absolute conic images by using scene structure information, and then recovering Euclidean reconstruction from projective reconstruction.

There exists no country level absolute convergence of the provincial productivity whether incorporating environmental factors or not.

3无论是否考虑环境因素，省级生产率均不存在全国范围的绝对收敛。

The results show that absolute convergence does not exist in rural economics among provinces,indicating that the economics growth of undeveloped provinces is not faster than that of developed provinces.

结果表明：我国农村省际之间经济并不存在绝对收敛，即落后省份经济的增长并不比发达省份增长快；但是存在条件收敛，即在控制了稳态的决定因素之后，落后地区的经济增长快于发达地区的经济增长，从而使差距缩小；在影响条件收敛的诸因素中，人力资本、产业结构以及科学技术对我国农村经济条件收敛的贡献最大。

The absoluteβ-convergence is not exists in the regional economic growth, which means there is no over take phenomena between the undeveloped and developed regions.

地区经济增长过程中并不存在绝对β收敛现象，即并不存在落后地区对发达地区的赶超。

The results show that absolute convergence does not exist in rural economics among provinces, indicating that the economics growth of undeveloped provinces is not faster than that of developed provinces. However, the economic development in rural China is characterized by the conditional convergence, that is, if the decisive factors stability is insured, the economic growth of undeveloped provinces would be faster than that of developed provinces. Thus, the disparity among them could be narrowed.

结果表明：我国农村省际之间经济并不存在绝对收敛，即落后省份经济的增长并不比发达省份增长快；但是存在条件收敛，即在控制了稳态的决定因素之后，落后地区的经济增长快于发达地区的经济增长，从而使差距缩小；在影响条件收敛的诸因素中，人力资本，产业结构以及科学技术对我国农村经济条件收敛的贡献最大。

Government transfer payment is an important policy instrument to coordinate regional economy. This paper measures and analyzes the convergence test of income during 1995-2004, and analyzes the relationship between transfer payment after tax-sharing system reform in 1994 and regional economic convergence through econometric analysis. It concludes that income has neither absolute convergence nor conditional convergence in the nationwide. The overall transfer payments did not meet the goal of narrowing income gap, especially in the central and western regions.

转移支付是政府协调区域经济的重要政策手段，本文测算和分析1995年－2004年省区收入的收敛检验，并运用计量方法分析了1994年分税制改革以后转移支付与地区经济收敛的关系，得出的结论是：收入的收敛模式在全国范围内没有绝对收敛，也没有条件收敛，转移支付总体上没有达到缩小地区收入差距的效果，并且突出表现在中部和西部地区。

From 1978 to 2000, there was not σ-convergence of the PGDP growth in Jiangsu province; From 1984 to 1993 and since 1999, there was not σ-convergence of the per capital net income of rural households growth, but from 1993 to 1999, there was a -convergence; From 1978 to 2000, there was not absolute β-convergence of the PGDP growth in Jiangsu province, but there was conditional β-convergence and the convergence intensity was feeble, half-lifecycle is comparative long, the least half -time of the undeveloped region will catch up with the developed region was 115 years; From 1994 to 2000, there was club-convergence hi the northern Jiangsu and the Middle Jiangsu, but there was not club-convergence in the northern Jiangsu.

第四，基于经济增长收敛的理论与方法，对江苏省区域经济发展的收敛性进行了研究。1978一2000年，江苏省人均GDP总体上不存在u一收敛；农民人均纯收入增长在1 984一1993年及1999年以后不存在a一收敛、在1993一1999期间存在a一收敛；1978-2 000年，人均GDP增长总体上不存在绝对p一收敛，但存在条件p一收敛，收敛的程度较弱，半生命周期比较长，落后区域要缩小与发达区域经济差异的一半最少也需要115年；1 994一2000年，在经济比较发达的苏南和苏中内部存在俱乐部收敛，在苏北内部不存在俱乐部收敛趋势。

The model of absoluteβconvergence and conditionalβconvergence tellsthat overall regional disparity of energy productivity is becoming narrow gradually, howto consolidate and develop such trend has a long way to go.

绝对β收敛和条件β收敛模型研究表明，中国地区间能源生产率总体差异正在逐步缩小，巩固和发展这一趋势尚任重道远。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
