2 STR-PCR We analysed the results of STR with the silver dye in the beginning. The silver dye of STR analysis on a sporadic DMD family shows the band confirmation is subjective by eyeballing. It can not detect the small repeats and the size of polymorphic fragments. For limitation of the silver dye, we analysed the band size of STR with the SAGAGT Genotyping System. Primer are designed according to the nucleotide sequence of five STR markers (located in 5' terminus and intron 44, 45, 49, 50) of dystrophin gene. The 5' end of the forward primer are attached a M13 tailed primer which conjugated to the infrared flourescent dye.

根据dystrophin基因5个多态位点（44、45、49和50号内含子以及5'端启动子区的序列）设计引物，在这些STR的上游引物5'端加一可被红外线荧光物质IRDye700识别标记的M13fw的尾：CAC GACGTT GTA AAA CGA C 通过PCR扩增出重复序列本身，经高分辨率的变性聚丙烯酰胺凝胶电泳后，利用红外激光遗传分析系统及SAGA〓基因分型软件对凝胶上的扩增产物及内标的位置，进行扫描分析，确定产物片段的大小。

From probability consideration, the curing theory of A〓+A〓-type and A〓+ B〓-type polymerization involving initiation stepis proposed. The sol-gel distribution equations which can describethe behaviour of the conversions in the curing process are givenand the gelation condition, the number fractional distribution andits invariant property are obtained.
