The purpose of this dissertation is to study a principle or method to describe and analyze the complex problems with high gradients arising from practical engineering. The main contents cover:1. The Bezier function was introduced to approximate high gradient functions, and a suitable coupled function was derived. Some detail numerical results show that the Bezier-based function is dominant over other combination function such as polynominal and trigonometric series, when to describe a high gradient function.

针对工程中大量存在的高梯度问题进行函数逼近的研究，引入Bezier函数对高梯度问题进行函数逼近，构成以Bezier函数为主的复合逼近函数，数值考证表明：与常规多项式插值函数的逼近及"幂／三角"复合函数的逼近相比，基于Bezier函数的逼近函数对高梯度问题的描述具有明显优势。

Results The long term results of the vascularized fibular graft varied in different types of bone defects. Nine patients with congenital pseudoarthrosis of tibia had the limb function restored in 65％ and one had nonunion of fibular graft, 3 fractures(7 times), and 5 angular deformities. Three patients with congenital radial deficiency had 62％ restoration of the limb function. All of them showed early closure of epiphyses of the grafted fibulae. Five cases with osteomyelitis and bone defects combined soft tissue deficiency had 94％ restoration of the limb function, and only one occurred fracture of fibular graft. One case with soft tissue defect and concomitant ulnar defect, ulnar nerve and median nerve injury, 67％ function of limb was recovered, and union of fibula graft was good. 100％ function of limb was recovered in 1 case with cavernoma of radius and without occurring valgus deformity of donor site.

In 1991, a young Italian scientist, Walter Fontana , showed mathematically that a linear sequence of function A producing function B producing function C could be very easily circled around and closed in a cybernetic way into a self-generating loop, so that the last function was coproducer of the initial function.

This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent function f with even variables, m is no more than half of?. It also shows that when the input dimension n is odd, the regular generalized vector Bent function and the inverse regular generalized vector Bent function do not exist. This may prevent the cryptology designer from seeking the inexistent function.

摘要该文完善并拓展了Nyberg(1991)的关于广义向量Bent函数性质的结论，相应于Nyberg给出的正则广义向量Bent函数，提出了&负则的广义向量Bent函数&的概念：得到有偶数个输入的负则的广义向量Bent函数输出维数也不大于输入维数的一半；证明了奇数个输入的正则和负则的广义向量Bent函数都不存在，这些结果的给出，可使密码设计者避免一味去寻找某类不存在的函数。

The basic function of county government is to perfect the configuration of market economy system to create basic conditions for the performance of market system by institutional innovation; the guiding function refers to the one that county government creates the development plans, strategies, policies and economic levers to promote the agricultural modernization, county industrialization,and urbanization for driving the county developmant; organizational function means that county government carries out the correct measures of industrial organization to avoid infavorable impact of overcompetition on economy and to improve the development and competitivity; regulatory function performs when county government regulates the conducts of market bodies by economic, legislative and administrative means to solve the externality and to sustain the development; and the complementory function acts on market by government supplying the public goods and harmonizing the social development.

基础性作用即县级政府通过一系列市场化的制度创新，建立完善了市场经济体制的基本框架，为市场机制发挥作用创造了基础条件；主导性作用即县级政府通过发展规划、发展战略、经济政策和经济杠杆，促进农业现代化、县域工业化和城镇化，使县域经济发展更具主动性；组织性作用即县级政府实施正确的产业组织措施，克服过度竞争对县域经济发展的不利影响，提高县域经济运行质量和竞争力；矫正性作用即县级政府通过一系列经济、法律、行政手段，对市场主体的行为进行调节，解决县域经济的外部性问题，使县域经济提高效率，实现可持续发展；补充性作用即县级政府发挥对市场的补充作用，主导公共产品供给，从根本上解决县域公共产品短缺问题，实现经济社会协调发展。

The cultural function is the basic function of education, other functions such as economical function and political function, etc. are refracted in the cultural function of education.

教育的基本功能是其文化功能，教育的其它功能是其文化功能的特定形式或在不同背景上的折射。

The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

This was not understood at the time, and therefore went unaddressed, until ascension became so distorted that we chose to stop ascending and wait for a time when all records would be revealed.

这在当时没有被了解，因此进行着无改编，直到提升变得如此扭曲，我们选择去停止提升并等待所有记录能被揭示的那一天。

The attack＇s nuisance value is increased because mobile phone networks also send notifications of new voicemail by sms,so an attacked phone may stop advising of new voice messages too,it warned.

它警告：这种攻击的危害增长是因为移动电话网络也会通过短信发送新语音邮件的通知。所以受到攻击的手机可也以停止新的语音信息的提示。
