dimensional perturbation的用法和样例：
例句
- A spin-dependent Lorentz violation would show up as a perturbation of the pendulum's oscillations that depends on the pendulum's orientation.
摆锤振荡时，若有与自旋相关的劳仑兹违逆，便会对摆锤的运动产生扰动，这样的扰动会因摆锤方向的不同而有所差异。 - The componentwise perturbation analyses of these two kinds of improved algorithms are also given, then the numerical stability of these algorithms are improved.
并且对这两种改进算法进行了基于分量的扰动分析，从而证明了它们的稳定性。
