The study found the first formant frequency, for vowel/i/ has no change, while the second formant frequency peak significantly shifted between the preprosthetic and postprosthetic speaking condition after anterior resection of maxillae, and found there is the correlation between the calculation of relative energy error value and the speech intelligible measured aurally (P【0.05).展开更多

Methods Mathematical model of fluid and proteinbalance of burn injured patient in acute phase was adopted and computer simulation of the system control wasutilized. The fluid resuscitation protocol designed by computer simulation were applied to twelvepatients.Results The new method has better effects with less side- effects. Conclusion The computer- simulationdesigned fluid therapy protocol provide a better resuscitation than the fluid therapy protocol produced by usingempirical formula.展开更多
