作者 高俊斌 《应用数学》 CSCD 北大核心 1992年第4期81-87,共7页
Urn模型的离散概率分布被用于构造逼近格式,具有Bernstein多项式的许多特性。本文用B网技术对Urn模型概率分布给出新的解释,指出了Urn模型B网的诸多性质,导出分布函数曲线的导数公式,构造了Urn分布的对偶基及与此相关的拟插值算子。

Objective To explore the effect of rehabilitat ion through analysis the early enteral feeding on the prevention of enteral infection in severely burned patients .Method Atotal of 22patients with severe bur ns were randomly divided into an early enteral feeding group(EF)and a delayed enteral feeding group(DF).The levels of serum endotoxin were d etected in the members of both groups in 1,3,and 5days .Result The levels of serum endotoxin in severely burned patients were significa ntly higher than in normal subjects(P <0.01).The levels of serum endotoxin in the EF group were significantly lower than in the DF group(P <0.01).Conclusion Early enteral feeding may decrease e n-terogenic infection and it helps the nutrition support,improve the patient resistance,facilitate the repa ir of damaged tissue ,so it contribut es to the rehabilitation of burned patien ts. 展开更多
