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。

Sequences of modified genes GOX and CP4-EPSPS in GM canola and that of modified gene Cryla in GM cotton were decoded and the conservative sequences of exogenous resistant genes: PLRVrep, PVYcp and CryⅢA in GM potato: New leaf〓 PLUS and New leaf〓 Y were confirmed using the modified exogenous gene decoding technique and isogenous sequence similarity BLAST analysis. Bases on DNA sequences studied above, conventional PCR primers were designed and selected in an optimized way and the conventional PCR detection protocol for exogenous resistant genes in 19 GM crops was established.
