这次展出的误认作品包括一幅杜勒的肖像画，后经研究判定并非出自其手；还有一幅波提切利的作品也是如此。

Among the mistakes included in the show is a durer portrait that later research determined was not by his hand; a Botticelli, too.

在此情况下可以对输入数据符号进行加权处理，从而得到一类MS K信号，这类MS K信号仍为等幅波、相位仍保持连续。

In these situations, one might apply additional input pulse weighting to form a class of MSK type signals which still maintain constant envelope and continuous phase.

这是上幅图中同样的声音信号形成的声图，但是菲舍尔用了另外一种不同形式的小波进行变换，而且在声图上玩了一些花样，得到了这样花朵锦簇的效果。

This is the same sound as led to the previous image, but Fischer has chosen a different type of wavelet to perform the transform and has played around with the result to produce a floral effect.

So, for example, if we were looking at the actual wave function, we would say that these parts here have a positive amplitude, and in here we have a negative amplitude.

我们看，一个波函数,我们说，它这部分幅值，为正,这部分幅值为负，当我们看。

Remember when we have waves we can have positive or a negative amplitude.

记住一个波会有,正的幅值和负的幅值。

So, what this means is that when we're looking at an actual wave function, we're treating it as a wave, right, so waves can have both magnitude, but they can also have a direction, so they can be either positive or negative.

这意味着,当我们看一个波函数时,我们把它看做一个波，波不仅有幅值，还有方向，所以它们可正可负，如果。
