At a glance of the molecular mechanism, one gene encoding 218 amino acids was identified from cDNA-AFLP differential study and then named as Ipomoea batatas MADS-box 1 gene (IbMADS1) based on earlier studies. From sequence alignment and phylogenic analysis, IbMADS1 exhibited a typical type II-MIKC structure, including two conserve domains, MADS-box and K-box.

The thermal decomposition processes of silver behenate have been studied by infrared spectroscopy,X-ray diffraction,combined thermogravimetry-differential thermal analysis-mass spectrometry,transmission electron microscopy.

利用红外光谱、X-射线衍射、热重-差热分析-质变联用及透射电镜等分析手段，研究了山嵛酸银的热分解过程。

The thermal behavior of silver behenate has been studied by infrared spectroscopy, X-ray diffraction, combined thermogravimetry-differential thermal analysis-mass spectrometry. The results indicated that complicated phase transitions took place while heating silver behenate,but there were two distinct thermal transitions. During the first transition at 138°C, the alkyl chains of silver behenate were transformed from an ordered into disordered state.

通过采用粉末X射线衍射、红外光谱、热重-差热分析与质谱联用技术，对山嵛酸银纳米晶体的热行为研究发现，山嵛酸银受热发生了一系列相转变，它有两个明显的突变：即在138℃左右，山嵛酸银的烷基链从高度有序转变为无序状态；在231℃左右，山嵛酸银发生了热分解，其主要分解产物为银纳米粒子和山嵛酸。
