9、Physics, on the other hand, has developed several models that explain how small perturbations can lead to wild effects.───从另一方面讲，物理学已经提出了若干模型去解释为什么微小的扰动能够产生无法控制的影响。
1、Unfortunately, these perturbations can not be joined continuously to those of the interaction region.
2、Small perturbations do not change a topological property.
3、Angular perturbations tend to increase instead of decrease.
4、Consequently only short range variations and perturbations in the field need be considered when studying the behaviour of a particle.
5、Perturbations in the orbit of the planet Uranus led to the discovery of Neptune in 1846.
6、Simulated annealing uses random perturbations to shake the parameter values out of a local optimum so that globally optimal values may be found.
7、Planetary perturbations make the earth's orbit about the sun irregular.
8、Perturbations of the force field will cause changes, or variations, of the displacement field.
