In particular, for the case of small initial data with compact support, the author gives the life-span of classical solutions and its application to nonlinear wave equations.
特别地,对紧支集小初值的情况,给出了经典解的生命区间及其在非线性波动方程中的应用。
In this paper, we give an algorithm of construction compact support bivariate orthogonal scaling function whose dilation matrix is 2i, the correspond wavelets are also offered.

B-splines is an easiest function which has compact support and is efficient to put into practice via software and hardware, so we use B-splines wavelet to detect welding seam edge.
基数B样条函数可以说是对于软件或硬件实现都是比较有效的具有小支撑的最简单的函数,文中采用B样条小波进行焊缝坡口边缘检测。
Both initiatives were established with the critical support of the Global Compact.
两项倡议的建立都得到了全球契约的关键支持。
The goal of this and other related computing research efforts is to create new, compact supercomputers to support the Defense Department’s growing need for applications and processing capability.
该项目与其他相关计算研究工作的目标是创造新的紧凑型超级计算机,以支持*********日益增长的应用和处理需求。
在数学分析中,一个函数被称为具有紧支撑(compact support),是指该函数仅在某个定义域内的紧集(compact set)上取非零值,而在此紧集之外处处为零。
核心概念拆解:
数学定义: 设 f: $mathbb{R}^n$ → $mathbb{R}$(或 $mathbb{C}$)是一个函数。f 的支撑集定义为: $$mathrm{supp}(f) = overline{{x in mathbb{R}^n mid f(x) eq 0}}$$ 如果 $mathrm{supp}(f)$ 是 $mathbb{R}^n$ 中的一个紧集(即有界闭集),则称函数 f 具有紧支撑。

注:该术语在工程领域常被简称为"紧支集",在拓扑学中与局部紧空间性质密切相关。具体应用案例可参考泛函分析教材。
