According to optical theory of distortion and utilizing BP neural network to approach nonlinear distortion, distortion correction mathematic model of whole field was set up through training the distortion measurement data which were measured by distortion detection device. This device has eleven equidistance points of laser goals and is designed based on the basis of distortion mechanism and radical character.

In this paper, three methods for color image retrieval have been presented: hypercomplex SVD image retrieval, combination of hypercomplex convolution filter and hypercomplex SVD image retrieval and hypercomplex matrix correlation image retrieval. We made comparison among these hypercomplex-methods, and compared them with the traditional image retrieval methods. Experiment results showed that the hypercomplex-methods we presented in this paper could well conquer the problems existed in traditional image retrieval methods, and their retrieval results are much better. Meanwhile, this paper presented a new color image quality assessment based on hypercomplex SVD. It is a novel color image quality assessment that can be used as a graphical or a scalar measure to predict the distortion introduced by a wide range of noise sources. It reliably measures the distortion not only within a distortion type at different distortion levels, but also across different distortion types.

提出了超复数奇异值分解检索法，超复数卷积滤波与超复数奇异值分解相结合的检索法以及超复数矩阵相关检索法等三种超复数彩色图像检索方法，在对提出的三种算法进行比较的同时也将其与传统图像检索方法进行了比较，结果证明，超复数彩色图像检索法能较好地克服传统图像检索方法存在的问题，且检索结果更优；同时，本文提出了基于超复数奇异值分解的彩色图像质量客观评估法，这种全新的图形化与数值化相结合的方法不仅能够准确评估出彩色图像的不同失真等级，还能够区分不同的失真类型，从真正意义上实现了彩色图像的质量评估。

For weak nonlinear distortion, the expressions of total harmonic distortion, the second order intermodulation distortion(IM2 ), the third order intermodulation distortion(IM 3) and intercept point(IP 3) are deduced. With the aid of software Multisim, we simulate transistor common emitter amplifier, transistor common emitter amplifier with resistor in emitter, differential amplifier and differential amplifier with resistor between emitters. The simulational results and theoretical analyses are almost the same.

distortion：失真

从神话般的八十年代以来,内置过载的音箱充斥着市场,这还不算那些过载(overdrive),失真(distortion),以及重金属(heavy metal)单块. 这些科学的奇迹使那些用来过载音箱的绕数过多的拾音器不再需要了.

distortion：扭曲变形

这是一段漫长缓慢的过程,因为许多有问题的DNA必须先修补好之后,才能够将祖先立体影像肉身化,而不致产生扭曲变形(distortion)的情况. 而这也是我这一生的目的之一:修补恩纽时期核子辐射尘所造成的损伤,使未来上升之途更加顺畅.

distortion：畸变

场曲六 畸变(Distortion)前面所说各种相差除场曲外,都影响象的清晰度. 畸变是另一种性质的相差,光束的同心性不受到破坏. 因此,不影响象的清晰度,但使象与原物体比,在形状上造成失真. 畸变

distortion：变形

现代"形式主义"画家康定斯基(Kandinsky)曾把绘画中的"再现因素"(represen tative ele-ment)贬称作"障碍"(impediment),欲"地加以"变形"(distortion)改造.--明代的徐渭有意识地用黑白所区别:"叙事性(narrative)必须有一个故事情节;

Harmonic distortion：谐波失真

*谐波失真(harmonic distortion) 指原有频率的各种倍频的有害干扰. 放大1kHz正弦波时将会产生2kHz的二次谐波和3kHz的三次谐波以及许多更高次的谐波. *尖刺(harsh) 指中频高段过多. 在频率响应的2kHz到6kHz之间有尖峰值或是在数字式录音机的低通滤波器中有过多的相位移.
