以InP单晶中的等电子杂质为例，根据固溶强化模型，考虑了等电子杂质在InP单晶中的溶解度以及掺入杂质与基质原子之间共价半径之差引起的弹性失配，计算了这些杂质在InP中对位错的钉扎力可达10〓～10〓达因/厘米〓，从而很好地解释了等电子杂质降低位错密度的作用。

Firstly, a series of organic molecules which use phthalimido group as electron acceptor, N as electron donor, COO~- as eletrofugal group were synthesized based on SET-promoted photocyclization processes. These compounds were irradiated by 500 W ultraviolet under nitrogen atmosphere in room temperature. After filtration of the photochemical character of these molecules, substrate S1 and S2 were selected as appropriate model reactants. Secondly, the monosubstituted derivatives at the 6-position ofβ-cyclodextrin were synthesized as chiral template of photocyclization.
