High resolution rotated flux scheme for two-dimensional magnetohydrodynamics equations(二维磁流体方程的高分辨率旋转通量格式)

open access: yesZhejiang Daxue xuebao. Lixue ban
The rotated flux method could be used to effectively eliminate the shock instability of the approximate Riemann solver and suppress the generation of non-physical phenomenon if the equations to be solved meet the rotational invariance.

复苏后综合征的死亡危险因素及预后数学模型研究

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2008
[目的]探讨复苏后综合征(PRS)的死亡危险因素,利用有统计学意义的因素建立数学模型,对PRS的预后进行预测,针对性地指导临床治疗。[方法]回顾性分析总结我院近7年来确诊的63例PRS患者的临床资料,按复苏后30 d时的预后情况分组,生存组24例,死亡组39例,基于相关影响因素的单因素统计分析,进而行Logistic多元回归分析及Fisher判别分析。[结果] 单因素分析结果提示自主呼吸、谷草转氨酶、谷丙转氨酶、消化道出血、凝血酶原时间、瞳孔对光反射消失、格拉斯哥评分、自主循环恢复(ROSC)时间 ...
