Up to now we have restricted ourselves to one-dimensional, one-particle systems . 迄今，我们限于一维一粒子体系。
In one dimension, any force that depends only on position is conservative . 一维运动中，凡只取决于位置的力都是保守力。
Thus what is now called the wave equation in one spatial dimension appears for the first time . 这样一来现在称为一维的波动方程就第一次出现了。
Since sound waves are longitudinal, only one dimension need be considered to obtain the sound wave solution . 由于声波是纵波，所以为了得到其解，只需考虑一维就行了。
In this section we will increase our quantum-mechanical repertoire by solving the schroedinger equation for the one-dimensional harmonic oscillator . 本节我们将用求解一维谐振子的薛定谔方程以提高我们的量子力学技能。
Perhaps the simplest illustration of the role of stress waves in dynamic crack propagation and crack arrest is given by the one-dimensional analysis of the double torsion specimen . 也许最简单地说明在动态裂纹扩展和止裂中应力波的规律是由双扭（DT）试件的一维分析给出的。

Then ascension towards another dimension can begin 之后提升到另一维度才能开始。
Objects , starting at the specified index in the target array 对象复制到一个一维
