nonlinear /nɒnˈlɪnɪə/

also non-linear

• 1. 

  ADJ If you describe something as nonlinear, you mean that it does not progress or develop smoothly from one stage to the next in a logical way. Instead, it makes sudden changes, or seems to develop in different directions at the same time. 不符合逻辑的; 非线性的

  例：

  Environmental systems tend to be nonlinear, and therefore not easy to predict.

  环境系统一般是非线性的，所以很难预测。
