unbounded function 中文意思是什麼
unbounded function
解釋
無界函數-
The result can be used in control problems whether the time interval is finite or infinite, the control set is bounded or unbounded, and also for systems with a weak differentiable function, i. e., the function f is only strong continuously g - differentiable but not f - differentiable. so, th 6. 2. 7 is a uniform theory of optimal control, and it has wide - ranging applications
可以看到，我們的結11摘要果可用於有限時域和無限時域、有界控制和無界控制、並且對系統中函數f的可微性要求也有較大的減弱? f對狀態變量x可以是僅有強連續的g一導數、不要求為f一可微。 -
In this paper, we discusse the stability of perturtation of m - p inverses of closed operator function and then the stability of least square solution of elliptic partial differential equations of second order with unbounded coefficients
本文討論了閉運算元的m - p廣義逆的擾動，並由此討論首項系數本質無界的二階散度型橢圓型微分方程的最小范數極小二乘解的穩定性 -
We get the estimates of the upper bounds of hausdorff and fractal dimensions for the global attractors. in section 5. 3, the cauchy problem is studied, by using the weighted function space and the interpolating inequality, the existence of the global attractors for the damped generalized coupled nonlinear wave equations in an unbounded domain is proved. in section 5. 4, the time periodic solution problem of damped generalized coupled nonlinear wave equations with periodic boundary conditions is studied, the existence of time periodic soluation of this problem is proved by using the convergence of approximate time periodic solution sequences
第五章，考慮了一類廣義耦合的非線性波動方程組，在第二節中討論了周期初值問題，證明了整體光滑解的存在性和唯一性，得到了整體吸引子，給出了hausdorff維數和分形維數的上界估計；在第三節中討論了cauchy問題，利用加權函數和加權空間的插值不等式，證明了無界區域上整體吸引子的存在性；在第四節中證明了時間周期解的存在性。 -
With the conception, and example of " system ", we see that the weak - smooth system not only exists, but also genuinely contains the systems discussed in many literatures ( and we call these systems as " smooth system " ). hence, the optimal control problems for weak - smooth system includes the relevant ones for smooth system, and thus concentrates the scattered problems and the deliberations - - such as infinite time interval, unbounded controls, and function in system not being f - differentiable, etc
從弱光滑系統的概念及該章給出的系統的例子，可以看到弱光滑系統不但存在，而且真包含許多文獻討論的系統（本文稱為「光滑系統」 ）為特例；進而，弱光滑系統的最優控制問題就包含了光滑系統的有關問題，其結果也使當前對一些零散的問題的研究? ?包括無限時域和無界控制問題等? ?得到了統一。 -
We consider the traveling waves of a delay cnn system with the output function f given as a non - linear function in the latter. we show the existence of monotone traveling waves solutions and describe the global structure of traveling waves such as monotone, damped oscillation, periodic oscillation and unbounded etc as the wave speed c is classified in r
第二部分我們考慮具時滯非線性cnn系統模型，得出方程單調行波解存在，並將波速c r分成若干個區間，得出c在各個區間時行波解曲線相應的類型包括單調、衰減振動、周期振動、無界等類型。 -
In chapter 1, we review the history of optimal control theory and point out that there are still three basic problems in optimal control research, i. e., infinite time interval, unbounded controls, and function in system not being f - differentiable. we see that it is still a weakish in optimal control theory to overcome these difficulties
在第一章中，我們回顧了最優控制理論的發展歷史，提出了當前研究中仍存在的三個基本問題? ?即無限時間區域問題、無界控制問題、以及系統函數不為f -可導問題。
