一类具有变指数椭圆型方程熵解的存在性

哈尔滨理工大学学报 2022年第3期27卷 147-156页

作者：吕月明刘洋哈尔滨理工大学理学院哈尔滨150080

为了研究一类具有变指数的拟线性椭圆型方程的熵解问题,在算子条件弱化后的情况下,先建立了椭圆型方程的逼近问题,然后运用Sobol.v嵌入定理、vitali定理等工具,得到了椭圆型方程熵解的存在性结果。

[目的]研究洗胃对应激与非应激状态下急性酒精中毒大鼠胃黏膜的影响。[方法]采用析因实验设计,将120只Wistar大鼠分为应激后酒精中毒不洗胃组、应激后酒精中毒洗胃组、酒精中毒不洗胃组、酒精中毒洗胃组、空白对照组,复制应激与非应激酒精中毒模型,给应激后酒精中毒洗胃组和酒精中毒洗胃组大鼠洗胃,直至洗出液用vitali反应检查法检测洗出液呈无色为止。各组分别于酒精中毒后2h、24h、48h处死8只大鼠,制备胃黏膜大体及光镜标本,并观察胃黏膜的病理变化,进行胃黏膜损伤评分(l.)。[结果]在排除时间因素的影响时,应激后酒精中毒洗胃组与应激后酒精中毒不洗胃组l.差异有统计学意义(Pl.差异有统计学意义(Pl.差异均有统计学意义(P<0.05)。分组因素和时间因素有交互作用。[结论]应激状态下急性酒精中毒后清水洗胃会加重胃黏膜的损伤,不主张洗胃;而非应激状态下急性酒精中毒后,清水洗胃会加快胃黏膜的修复,提倡洗胃。消极的心理因素与疾病的发生、发展密切相关。
