According to the degrees of PSC they have,Shanghai-accented Mandarin interlanguage are classified into four stages as elementary ,intermediate ,intermediate-advanced and advanced.Then the phonologies of Standard Mandarin and Shanghai-accented Mandarin interlanguage are compared in order to find out the phonological differences between these two dialects. Based on the statistical results, the writer chooses ten typical kinds of pronunciation errors of finals according to the rates of pronunciation errors of finals on stages.Then, the phonetic level analysis is made on them for the four stages respectively. Furthermore, acoustic features of vowels, diphthongs, triphthongs and vowels with nasal endings are analysized and compared by plotting vowel charts and formant patterns for them.

The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.
