Based on＂The Data Bank System of the Standard Phonetic Features of Different Level in PSC＂, the thesis analyzes the variants of affricative versus fricative in syllables: z, c ,s - zh, ch, sh - j, q, x which are obscure in physiology; analyzes timbre phonetic variants aroused from the different match of seven main simple vowels and initials as well as the tonal patterns with the help of drawing the synthetic spectrograph and pitch spectrograph. So that the data can be offered to describe phonemes in 396 syllables in common use according to the acoustic analysis.

The results were analyzed with the statistical software package spss10.0.results ①between two groups,there was no significant difference about the affection of age,sex and the destribution and location of aneurism on prognosis outcome(p＜0.05).however,the grading of hunt hess and fisher in group a(gos＞3) showed significantly lower than in group b(gos≤3),（p＜0.001）;② there was no significant difference in the frequency of heart rate, st elevation, st depression,t wave inversion,u wave inversion and ventricular arrhythmia(p＞0.05).the frequency of abnormal q wave, supraventricular arrhythmia and the ecg scores in group a showed significantly lower than in group b （p＜0.05,p＜0.001）;③the ecg scores was the most powerful multivariate risk stratified(ecg ≥5 vs ecg＜5; p=0.002,or=0.010,95%ci 0.001~0.173).conclusion the ecg score, a new and simple method of semi quantification, was a powerful risk predictor for patients with sah.
