用正交试验法确定最佳调剖施工参数

针对文明寨油田地质特征和开采现状，按照油藏数值模拟原理，以调剖井对应油井的增油降水创经济效益大小为考核指标，运用正交试验的均衡分散性和整齐可比性及Ｌ９（３４），正交表进行调剖最佳施工参数试验．经现场试验、分析、讨论发现：影响调剖效果的主要因素是措施半径，其次为施工排量和注入方式，且最佳施工参数是措施半径在３．５ｍ左右，施工排量在１９ｍ３／ｈ左右，按连续注入方式调剖。经文明察油田、卫城油田、马寨油田５０井次现场试验证明，较好地改善了注水井吸水剖面，对应油井取得了明显的增油降水效果，收到了较好的经济和社会效益．

Research on consistency measurement and weight estimation approach of hybrid uncertain comparison matrix

The consistency measurement and weight estimation approach of the hybrid uncertain comparison matrix in the analytic hierarchy process （AHP） are studied. First, the decision-making satisfaction membership function is defined based on the decision making＇s allowable error. Then, the weight model based on the maximal satisfactory consistency idea is suggested, and the consistency index is put forward. Moreover, the weight distributing value model is developed to solve the decision making misleading problem since the multioptimization solutions in the former model. Finally, the weights are ranked based on the possibility degree approach to obtain the ultimate order.     

The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.     

量子退相干解释的再思考

量子测量退相干解释,在解决量子测量难题上正在取得进展。但量子测量退相干解释的具体模型,被测系统与宏观仪器所形成的纠缠态,在退相干解释理论体系中逻辑上并不自恰,退相干解释的应用模型仍存在重新建立的必要。
