A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

STFT 算法关键问题之一是窗函数的选择，矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗，但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差；其次，暂态信号中含有丰富的故障信息，傅立叶变换固定的频窗忽略了这些特征信息。

The watermelons, the citrullus lamtus or the stems and leaves thereof are taken as raw materials, and the extracting process comprises the following steps: firstly, the raw materials are washed clean and broken to separate the watermelon peel from the watermelon pulp for respectively extracting juice; the two juices are mixed, and micro-filtration and ultra-filtration are carried out to remove insoluble substances and macromolecular substances; and then reverse osmosis and nano-filtration are carried out to obtain the filtrate; the pH value of the filtrate is regulated and then a macroporous strong acid cation exchange resin column is added; and then ammonia water is taken as an eluant for isocratic elution; the eluent obtained is decompressed, distilled, deaminized, discolored, condensed and crystallized to obtain a white crystalline product of the natural L-citrulline extracted from the watermelons.

本发明方法以西瓜、打瓜或者其茎叶为原料，其过程为：首先将原料清洗干净，破碎后将西瓜皮西瓜瓤分开，分别进行榨汁；所得汁液合并，经过微滤和超滤除去不容物和大分子物质；然后再经反渗透和纳滤过滤；透过液调节pH值后通入大孔型强酸性阳离子交换树脂柱；然后以氨水做洗脱剂进行等度洗脱；将洗脱液减压蒸馏脱氨，脱色，浓缩结晶，得到西瓜提取天然L-瓜氨酸白色结晶产品。
