与其它谱分析方法(如傅立叶谱和周期图法)比较，最大熵谱分析方法具有不受取样长度限制、对频谱分辨率较高等优点。

Compared with other spectra analysis, such as Fourier entropy and periodic picture, this method has many advantages such as no limit to sampling length and higher resolution to the spectra.

该函数生成由字母a至f，数字和连字符组成的随机字符串，并且不必要地限制关键字空间，导致熵的削弱。

This function generates a random string composed of letters a to f, Numbers and hyphens and unnecessarily restricts the key space, resulting in a weakening of the entropy.

利用熵密度对自由能密度的限制，导得熵密度变化率。

By taking use of the limit of entropy density on free energy density, it deduces changing rate of entropy density.
