acoustic = acous(听) + tic(形容词) = 有关听的→声学的
混乱的
chaotic
常考释义
So, well, the echoes from a tree are going to a mass of chaotic acoustic reflections, right, not like the echo from a moth.
因此，从树木上反射的回声将会是大量且嘈杂的，是的，不像从飞蛾上反射回来那样简单。

The butterfly effect is a hallmark of chaotic systems.Simple systems are described by linear equations in which, for example,increasing a cause produces a proportional increase in an effect. In contrast,chaotic systems are described by nonlinear equations, which allow for subtlerand more intricate interactions. For example, the economy is nonlinear becausea rise in interest rates does not automatically produce a corresponding changein consumer spending. Weather is nonlinear because a change in the wind speedin one location does not automatically produce a corresponding change inanother location. Many (but not all) nonlinear systems exhibit chaoticbehavior.
蝴蝶效应是混沌系统的一个标志。简单的系统可以用线性方程组来描述，在一个线性方程式中，比如说增加变量的会使结果呈比例地增加。而相反，混沌系统是用非线性方程组来描述的，在非线性方程式中存在着更微妙、更复杂的关联。例如，经济是非线性的，因为利率的上升不会自动造成消费支出发生相应的变化。天气是非线性的，因为一个地点风速的变化不会自动造成在另一个地点也发生相应的变化。许多（但不是全部）非线性系统表现出混沌行为。

In fact, many chaotic systems have a kind of underlying order that explains the general features of their behavior even while details at any particular moment remain unpredictable. In a sense, many chaotic systems are “predictably unpredictable.” Our understanding of chaotic systems is increasing at a tremendous rate, but much remains to be learned about them.
并非像它们的名字所描述的那样，混沌系统是不完全随机的。事实上，许多混沌系统都有一种基本的规律来解释它们的行为的一般特征，即使在任何特定时刻的细节都是不可预知的情况下。从某种意义上说，许多混沌系统是“可预见地不可预测的”。我们对混沌系统的理解正在以惊人的速度增长，但仍有许多东西仍然有待我们去了解。

这些原因包括变化多端的大气波动，较慢却同样不稳定的海洋活动，地表变化以及冰雪的覆盖度。

但是，你看这幅画的背景，这个南瓜地里的妇女被一块地毯围着，而这个地毯是用粗犷的线条（broad thick brushstrokes 之前在说印象派时提到的） 所勾画的，并且这些线条都有点锯齿状的。
