本文以县域经济的发展是全面建设小康社会的关键所在为出发点，围绕"壮大县域经济"精神，按照"五个统筹"原则，通过对经济学中相关经济发展理论、比较利益理论、区域发展理论等理论的研究和认识，结合延边朝鲜族自治州的实际，分析了延边州县域经济发展中存在的问题和阻碍县域经济发展的原因，以"农业是稳定的基础，工业是发展的出路"为主线，以政府在市场经济和经济发展中的定位为主要内容，强调了制度在经济发展中的关键和保障作用，衡量一个制度是否有效率的标准应是更多的机会公平和更多的结果效益；强调了在欠发达县域经济中，经济要取得大的和长足的发展，稀缺资源应得到充分的利用、并应向有较大前向效应的工业发展倾斜的观点，并在此基础上指出了欠发达县域经济的发展方向是传统中小工业，同时，针对以往的一些促进经济发展的政策提出了一定的改进的意见；强调了在市场经济条件下，必须更加注重社会保障机制。。。

From the matrix theory and the general principle of the iterative convergence of the linear coupled equations, this dissertation firstly proved the sufficient necessary convergent conditions for CMAC batch learning as well as the necessary convergent conditions for CMAC incremental learning, in which no additive conditions were needed.

To cherish peace and friendly intercourse with all nations having correspondent dispositions; to maintain sincere neutrality toward belligerent nations; to prefer in all cases amicable discussion and reasonable accommodation of differences to a decision of them by an appeal to arms; to exclude foreign intrigues and foreign partialities, so degrading to all countries and so baneful to free ones; to foster a spirit of independence too just to invade the rights of others, too proud to surrender our own, too liberal to indulge unworthy prejudices ourselves and too elevated not to look down upon them in others; to hold the union of the States as the basis of their peace and happiness; to support the Constitution, which is the cement of the Union, as well in its limitations as in its authorities; to respect the rights and authorities reserved to the States and to the people as equally incorporated with and essential to the success of the general system; to avoid the slightest interference with the right of conscience or the functions of religion, so wisely exempted from civil jurisdiction; to preserve in their full energy the other salutary provisions in behalf of private and personal rights, and of the freedom of the press; to observe economy in public expenditures; to liberate the public resources by an honorable discharge of the public debts; to keep within the requisite limits a standing military force, always remembering that an armed and trained militia is the firmest bulwark of republics——that without standing armies their liberty can never be in danger, nor with large ones safe; to promote by authorized means improvements friendly to agriculture, to manufactures, and to external as well as internal commerce; to favor in like manner the advancement of science and the diffusion of information as the best aliment to true liberty; to carry on the benevolent plans which have been so meritoriously applied to the conversion of our aboriginal neighbors from the degradation and wretchedness of savage life to a participation of the improvements of which the human mind and manners are susceptible in a civilized state——as far as sentiments and intentions such as these can aid the fulfillment of my duty, they will be a resource which can not fail me.

我认为应珍视与所有志同道合的国家的和平相处和友好往来；对所有交战国则保持真诚的中立；在任何情况下，对分歧都应采取友善的协商和理智的调停，而不能诉诸武力加以解决；来自国外的种种阴谋诡计和对外国的偏袒不公，对任何国家来说都是卑下可鄙的，对自由国家则更是危害非浅，故应予以摒弃；要培育一种独立的精神，这种精神非常公正而不会侵犯他人的权利，非常自尊而不会放弃我们自己的权利，非常开明而不耽溺于我们自己毫无价值的偏见，非常高尚而必然鄙弃他人抱有的偏见；要把各州的团结作为我们和平与幸福的基础；要拥护作为联邦凝聚剂的宪法，不仅维护它的权威，而且遵从它的限制；要尊重保留给各州和保留给人民的各项权利和权力，这对整个制度的成功同样休戚相关和不可或缺；信仰的权利和总价的功能已然明智地排除在民事管辖的范围之外，故应避免加以丝毫的干涉；要维护旨在保障私人权利、人身权利和出版自由的其他有益规定的全部活力；政府开支要厉行节约；要通过光荣地清偿公债以调动公共资源；要把常备军事力量控制在必要的限度以内，应时刻牢记，一支训练有素的武装民兵便是所有共和国最坚强的堡垒，没有常备军，他们的自由决不至于陷入危险的境地，而庞大的武装则未必意味着安全；要采用合法的手段推动有利于农业制造业和国内外贸易的各项改进措施；要以同样方式支持科学的进步和知识的传播，此乃真正自由的最佳养份；要继续执行慈善计划，这些计划一直都在值得称道地实施，以改造我们的土著邻居，使他们摆脱野蛮生活的堕落和不幸，得以分享文明状态下人们在心灵和举止上所惯有的各种改善成果。以上种种想法和打算，只要有助于我完成使命，便是不会令我失望的一个源泉。

Naturally,we confront with such a problem:can we generalizethe systematic work on the classical boundary value problem for analytic func-tions and singular integral equation to Clifford analysis?And so this problemhas especially theoretical and practical meaning,and naturally this problem hasbecome a common hot topic for mathematicians at home or abroad.

其结果在一定程度上推广了一些经典文献的结果，取消了这些在经典文献结果中对s=0或s=n的条件限制，需要指出的是，据作者所知，到目前为止，本文也是第一次系统而又比较深入地研究了取值在泛Clifford代数〓上的超复函数的性质，并获得了比较系统而又深入的结果；另外，本文还对Clifford分析中的某些比较特殊的Riemann边值问题与奇异积分方程做了一定程度的研究，由于文中所用的方法较曾经出现的文献而言有着根本的改进，因此，本文去掉了从前在这一问题的研究过程中所做出的一些不必要的条件限制，从而使得在比以往条件更弱的情况下，获得了比以前文献中更多的结果。

In the 2A1 distorted trigonal bipyramid structure ,the single non equivalent Ga atom has the population of 4s 4p ,while the two equivalent Ga atoms have the population of 4s 4p .this compares with a Ga population of 4s 4p in the undistorted D3h structure ,hence the jahn-teller distortion causes depletion of the charge density on the 4s orbital of the non-equivalent Ga atom, and enhancement of charge density on the 4s orbital for the two equivalent atoms .an opposite trend is observed for the 4p orbitals of these Ga atoms .the P population for the two equivalent atoms is 3s 3p .the populations of the other 2B1 state with the edge-capped tetrahedral structure are similar with the exception that all three Ga atoms have similar but not identical populations .

Compared with the composite flocculant of WuHan petrochemical factory, its capability is superior to it: the efficiency of eliminating CODCr and SS are 28.75%and 8.29% respectively higher than those by flocculant of WuHan petrochemical factory, but the cost is46.63% lower; which is also far lower than the current average cost of petrochemical industry wastewater treatment. When dealing with papermaking wastewater, it can fully meet the require that WuHan ChenMing paper industry group put forward: The efficiency of eliminating CODCr higher than 25% based on the chemical cost controlled in 0.5 Yuan/ton sewage so as to better the gas float section. Those studies preparatorily show that this composite flocculant has particular effect and obvious economic、environmental benefit in industrial effluent treatment

However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。因此热力膨胀阀在变工况下供液量的调节方面需进一步改进。

Based on this, aim at the disadvantage on Wigner Distribution and Fractional Fourier Transform that can't restrain noise interference effectively when be used to detect Linear Frequency Modulated signals interfered by heavy noises, we proposed a improved WD. Simulation results show that this method can restrain noise interference effectively and improve the ability of LFM signals detection. On the other hand, in multi-component cases, WD suffers from the cross-terms, which may impair some of the auto-terms. In order to separate original multi-component signals into components and reconstruct them separately, we can use the method of optimal filtering in fractional Fourier domain. But this method also has a problem that if signals have aliasing in the fractional Fourier optimal domain as well, the reconstructed signals will be distorted. In this thesis, a novel method of quasi Fourier transform is proposed in order to solve the problem of multi-component signal reconstruction, and have good results.

在此基础上，针对Wigner分布和分数维傅里叶变换在处理高噪声背景下线性调频信号检测的问题时存在不能有效抑制噪声干扰的缺点，提出了改进Wigner分布的办法，该方法能够抑制噪声，提高信号的检测能力；针对Wigner分布在处理多分量非线性调频信号时存在干扰项的缺点，以及分数域最优滤波方法在处理多分量非线性调频信号分离重构问题时存在的局限性，该局限性表现为在对最优分数域上也有信号分量重叠的情况进行处理时重构信号发生畸变，提出了新颖的类傅里叶变换的方法，该方法对在最优分数域上也有信号分量重叠的情况也能处理，得到的重构信号失真很小。
