Pyrazole ketones were used as raw materials, to produce aminoatipyrine (AA) through methylation, nitration and reduction reaction, to form amido antipyrine (FAA) by formylation reaction.
Besides, there are about 3.5 percent of valuable materials in the impurities separated out.
First, they used high performance liquid chromatography (HPLC) method to determine related materials which influence analgin quality.

A Node-Based Strain Smoothing Technique for Free Vibration Analysis of Textile-Like Sheet Materials
Nguyễn T.
The present method illustrates that the numerical solution can help increasing the numerical accuracy and the computational efficiency for free vibration analysis of textile-like sheet materials.
The numerical results show that the solutions can improve numerical accuracy and computational efficiency subjected to free vibration analysis of textile-like sheet materials.

Introduction
Acoustic emission (AE) is a phenomenon of sound and ultrasound wave generation by materials that undergo deformation and fracture processes [1].
Fortunately AE signals could be used to detect material deformation and crack propagation, thus it can determine materials internal defects.
This materials show the typical four stages of tensile mechanical properties. ① Elastic stage: The deformation can be completely disappeared after relieve external forces. ② Yield stage: Strain has increased evidently, stress does not change or slightly decreased, this stage has an evident plastic deformation. ③ Intensive stage: Materials restore the ability to resist deformation.
It must increase the tension to make it continuing deformation, and stress of the materials in the intensive stage is large obviously more than the yield stage.

Ancient kilns typically use materials nearby, hence the raw material sources for kilns in different time and place are different.
