查询词典 time space

In actual application of remote sensing, remote sensing data have different resolution characteristic of space, spectrum and time.

在实际的遥感应用中，遥感数据具有不尽相同的空间分辨率、光谱分辨率和时相分辨率，通过图像融合技术可以提高遥感影像的空间分辨率、增强目标的特征、提高分类精度和动态监测及信息互补的能力，使得遥感影像融合技术成为遥感影像分析的一种重要工具。

Spectral element methods for partial differencial equation is introduced in this study from viewpoint of the collocation approximation of Chebyshev polynomial. Wave Equation and its space discretization are deduced. Two time integral methods, central difference method and implicit Newmark method, are introduced, and their stability and applicability are also discussed in some details. The significance of absorbing boundary conditions in spectral element methods for Aeroacoustics is explained, and Clayton-Engquist-Majda absorbing boundary conditions is emphasized and introduced, then the discrete scheme of this boundary conditions is deduced and applied to spectral element methods for wave equation.

This book analyzes, from a single perspective, some of the most important applications: the critical-point theory in classical statistical mechanics, the scalar quantum field theories in two and three space-time dimensions, and Tomonaga's theory of the ground state of one-dimensional Fermi systems.

这本书分析，从一个单个的视角，一些最重要的应用：在经典统计力学方面的临界点理论，标量量领域理论在2 和3 空间时间维，和Tomonaga 一维费密系统的基态的理论方面。
