In this study,we examined 3-month-old female mice from the senescence-accelerated prone mouse 8 strain and age-matched homologous normal aging female mice from the senescence accelerated-resistant mouse 1 *** from each strain were housed in an enriched environment（including a platform,running wheels,tunnel,and some toys）or a standard environment for 3 *** mice housed in the enriched environment exhibited shorter escape latencies and a greater percentage of time in the target quadrant in the Morris water maze test,and they exhibited reduced errors and longer latencies in step-down avoidance experiments compared with mice housed in the standard ***,brain-derived neurotrophic factor mRNA and protein ex- pression in the hippocampus was significantly higher in mice housed in the enriched environment compared with those housed in the standard environment,and the level of hippocampal brain-derived neurotrophic factor protein was positively correlated with the learning and memory abilities of mice from the senescence-accelerated prone mouse 8 *** results suggest that an enriched environment improved cognitive performance in mice form the senescence-accelerated prone mouse 8 strain by increasing brain-derived neurotrophic factor expression in the hippocampus.

为了提高再制造曲轴毛坯质量,建立退役曲轴再制造毛坯质量评价模型,从失效性、经济性、材料性3个层面系统分析其再制造性能。提出基于可拓法的失效性评价方法,根据专家经验知识设定失效性指标经典域,基于专家评测法获得的评价值作为可拓评价物元,建立综合函数与回收决策关联度对曲轴初步分类。在此基础上,对拟再制造的曲轴从设备成本、时间成本两方面进行综合经济性评价,再制造成本过高的作回收处理。对回收处理中材料性指标高于阈值的曲轴采取材料回收,其余废弃处理。最后,选取5个退役曲轴进行应用研究。实验结果表明:所采取的回收方式与实际工程经验相符,实现了曲轴分阶段、全方位的评价,便于企业决策。

影响机采方式选择的因素较多，多数又是不易定量描述的因素。我国油田一般都采用定性分析或类比的方法来描述机采方式，但存在着较大的盲目性。本文综合考虑了影响机采方式选择的九种因素，应用模糊数学方法建立了机采方式优选的综合评判模型；用统计方法建立了权数和隶属函数矩阵。编制的软件现场使用表明，用该方法优选机采方式不仅可使机采方式的选择定量化，而且优选结果与实际比较吻合，具有一定的实际意义。
