Linear distortion - frequency response, polar response, resonance - affects primarily the timbre and clarity of a loudspeaker.

线性失真-频率响应，指向性响应，共振，主要影响音色和清晰度。

Currently, magnetic resonance imaging (MRI) is used 1-3 months after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement.

目前，人们基于肿瘤大小和对比剂增强变化之原理，在治疗后1 - 3个月时，用磁共振成像(MRI)来评估解剖学上的肿瘤反应。
