After briefly reviewing the classification and respective characters of curves and surfaces modeling , the paper expatiates its history in cagd 文章最后在双曲函数空间中讨论了hc - b zier曲线曲面。本文首先回顾了曲线曲面造型方法的分类以及各自的特点。
A new predictive control algorithm , the function - space model predictive control ( f - mpc ) method , was developed based on a function - space optimization of the control input for attitude control 使用一种基于空间函数最优化的函数空间模型预测控制新算法( f - mpc )控制飞行器的姿态。
The basic properties of stable functions are given firstly . distributive dcpo is defined then and the stable function on this kind of dcpo is discussed in detail 给出了范畴slp的满子范畴笛卡尔闭的必要条件，即证明了slp的满子范畴中的指数对象就是稳定映射构成的函数空间
We study the test function space carefully , then make the correct choice of test functions , such that test function space matches with the solution function space in each problem 我们仔细地研究了试验函数空间并且正确地选择了试验函数，使得试验函数空间与解函数空间相匹配。
The solution to these problmes will not only enrich singular integral operator theory and function space theory , but also push on the research of partial differential equations 这些问题的解决不仅会极大的丰富奇异积分算子理论和函数空间理论，而且会对偏微分方程的研究起到推动作用。
The concept of the midpoint quasi - convex function is introduced , and some conditions are obtained to ensure that midpoint quasi - convex function is quasi - convex in the measurable function space 摘要本文提出了中点拟凸函数的概念，在可测函数空间中，给出了中点拟凸函数拟凸的若干个充分条件。
Essentially , a key problem on the interpolation by multivariate splines is to study the piecewise algebraic curve and the piecewise algebraic variety for n - dimensional space rn ( n > 2 ) 本质上，解决多元样条函数空间的插值结点的适定性问题关键在于研究分片代数曲线，在高维空间里就是研究分片代数簇。
After constrcting the perfective space , prove that this space is just the space of lebesgue integratiable function , thus explain that lebesgue integral is the form of the perfective riemann integral 在构造了完备化空间之后，证明了该空间就是勒贝格可积函数空间，从而说明了黎曼积分的完备化形式是勒贝格积分。
In this paper , the authors generalize the definitions of several spaces of holomorphic functions from the unit disc in c to the unit ball in c ( superscript n ) , where the growth of holomorphic functions depends on a weight function 摘要该文将几个全纯函数空间的定义从单复变数推广到多复变数，这些空间中全纯函数的增长性依赖于某个权函数。
In this paper , we study the dynamics of a two - neuron feed - back network model with two thresholds . we show that its equilibrium solution is converge for the prescribed limit threshold value 摘要研究一类具时滞和非连续型信号函数的双阈值二元神经网络模型解的渐近性，在一定的初始函数空间内，对信号函数阈值的一些不同取值范围，证明了其解的收敛性。
