Until recently, Wang X-S et al. [8] and Diederich et al. [9]reported the synthesis of 1,1-dicyanobuta-1,3-diene derivatives. but as far as we know, no condensation renactions with sarcosine or proline as catalyst have been reported.
Elemental analysis of the compound was performed on an Elementar Vario EL (Germany) instrument.

Wang et al. [5] reported the influence of grain size on mechanical properties and deformation twinning formed in a Fe-25Mn-3Al-3Si TWIP steel.
Wen et al.[6] conducted a research about the new Fe-Ni-Mn-Si-C TWIP steels, his reports said that, alloy’s strength and ductility can increase both with the increasing of the carbon content in austenitic steels, when carbon content reaches to 1.0(wt)%, alloy’s mechanical property achieves the maximum value.

Flavonoid content was determined according to the method of Chang et. al. [9] with a slight modification.
Ling et al. [10] found procyanidin compounds, which are classified as flavonoid, in the seed pod of lotus.

Researches have indicated that damping behaviour of Mg varies with large number of factors, such as solute element, grain size and its distribution, grain boundary condition, texture, and et al.

The factors influencing the hardness would be: (a) the type of the crystalline phases, (b) the magnitude, size, and distribution of the crystalline phases, (c) the casting defects, such as pore, inclusion, and at el.
However, the HRC hardness of Cu65Zr25Ti10 is less than that of Cu60Zr30Ti10 alloy, indicating that the HRC hardness of materials is related not only with the type of phases but also with other factors, such as the microstructure, defect, and et al.
