Temperature (T),PH,light intensity (I),dissolved oxygen (DO) and filling rate five factors plays important role in the process of ammonia nitrogen removal ,related data between ammonia removal and five factors was received through multi-factor orthogonal test,and established relations model between the five factor and nitrogen removal. The results show that five-factors had significant effect on AR,and the best combinations for removing AR was temperature 30 ℃,pH=7.0,light intensity 6 000 lux,dissolved oxygen 5.0 mg/L and the fill rate 10%. According to the experimental data,equation model was proposed and coefficient of determination R2 =0.864 8,P<0.05. Samples T-test was done between the model predictions and the actual measured values.Test results showed that the significant difference of overall mean value sig. (2-tailed) was 0.978 (P>0.05),it Shows that had no significant difference between model predictions and the actual measured value,and model had a high degree of fitting.展开更多
目的探究冠状动脉介入治疗对急性心肌梗死患者心功能的影响。方法选取2020年7月-2023年6月我院收治的86例急性心肌梗死患者,根据不同治疗方式分成对照组和观察组,每组各43例。对照组接受常规治疗,观察组接受冠状动脉介入,对比两组治疗...目的探究冠状动脉介入治疗对急性心肌梗死患者心功能的影响。方法选取2020年7月-2023年6月我院收治的86例急性心肌梗死患者,根据不同治疗方式分成对照组和观察组,每组各43例。对照组接受常规治疗,观察组接受冠状动脉介入,对比两组治疗前后心功能指标[左室舒张末期容积指数(LVEDVI)、左室收缩末期容积指数(LVESVI)、左心室射血分数(LVEF)]、6 min步行试验(6-minute walk test,6MWT)以及心脏不良事件发生率。结果治疗前,两组心功能标对比(P>0.05),治疗4周后,观察组LVEDVI、LVESVI下降较对照组明显,LVEF提升较对照组明显,具有显著差异(P<0.05);治疗1周后,两组6MWT对比无统计学意义(P>0.05),治疗2周、治疗4周后,两组6MWT逐渐提升,观察组较对照组提升明显,具有统计学意义(P<0.05);两组心脏不良事件发生率对比,观察组更低(P<0.05)。结论急性心肌梗死患者行冠状动脉介入治疗,能改善患者心功能,提高患者6MWT距,改善运动耐力,对于心脏不良事件发生率的降低有积极作用。展开更多
