Peck, R.B.[1],Atkinson[2] obtained a series of empirical formulas by analyzing a vast amount of surface subsidence data and engineering data; recent studies by H.Shen et al. [3] have researched the effects on the stress and strain of the nearby subway tunnel during the foundation pit excavation through three-dimensional numerical analysis; based on a large number of field trials, EL Gonnoun,i M. et al. conducted a large number of research to analysis how the uncertainty of soil parameters influent the deformation on the surface during underground construction.

Winterbottom et al. 1997 [4] have established a general reaction scheme for the reaction, using a 5% Pd/C catalyst.
Huang et al., 2006 [9] reported a highly active Pd/SiO2 catalyst (due to the size effect of supported Pd particles) generated in-situ from Pd 2+/SiO2 for the Heck coupling.
