From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.
从以省区为单元的中国地区经济发展差距形成的产业构成来看,第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者,居主导地位:但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后),第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间,中国地区经济增长并没有出现绝对收敛趋势,而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快,东部地区平均经济增长速度比中部地区高1个百分点左右,比西部地区高接近2个百分点,地区间经济增长速度存在显著的差异。

In this paper,a systematic direct perturbation method of dark solitons is found.Having analyzed the mistakes in earlier works on perturbation method for dark solitonsand essence of the direct perturbation method for bright solitons,we notice that to in-troduce the adjoint solutions of the squared Jost solutions and to prove the completenessare crucial to the problem.Giving up the unnecessary scheme of introducing the adjointoperator in the bright soliton case,we directly find the adjoint solutions by meetingthe demand for the orthogonality that inner product of the squared Jost solutions andits adjoint should be proportional to a δ function in the case of continuous spectra.The corresponding adjoint operator is thus found.Taking into account the reductiontransformation,we find a correct description for the completeness of the squared Jostsolutions and directly verify its validity with explicit expressions of the squared Jostsolutions.
本论文建立了系统的暗孤子直接微扰方法,在对前人关于暗孤子微扰方法的错误以及亮孤子直接微扰方法的本质作了充分的分析后,认识到引入平方Jost解的伴随解和证明完备性是问题的关键,撇开过去亮孤子情况首先引入伴随算子的非必要作法,直接从平方Jost解与其伴随解的内积在连续谱时正比于δ函数这一正交性要求出发,找出了伴随解,同时得出了应有的伴随算子,在考虑到约化变换性后,得到了暗孤子情况的平方Jost解的完备性的正确表述,并在单个暗孤子的情况利用平方Jost解的显式直接验证了它的正确性。

An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

Huawei's boss, Ren Zhengfei, is a former Chinese army officer, and Britain's spies fret that network equipment that will be used by firms, households and government departments could come with hidden "backdoors" that would let Chinese snoopers evade easy detection. In 2008 America's Congress blocked Huawei's plans to buy 3com, another computer-equipment firm, citing similar security worries.
