This article discusses it from reverse logistics , points out the strengthening function of reverse logistics to competitive superiority , analyzes hesitating of enterprises about executing reverse logistics and brings forward some corresponding suggestion 在论析逆向物流对企业竞争优势强化作用的同时，也分析了企业实施逆向物流的困惑，并提出了一些相应建议。
Abstract : enhancing function of pulsating draught for sintering process is studied with simulative burden in the laboratory . the experiment results indicate that sintering velocity is the fastest along with appropriate pulse draught frequency when negative pressure is lower 文摘:采用模拟原料，在试验室内的脉动烧结装置上，进行脉动气流烧结试验，探讨了脉动气流的频率变化和抽风负压等因素对烧结过程的强化作用
Based on the analysis and some typical data of petroleum basins in china and world , it discusses some important expression forms and majo r research methods of thermal fluid flow , and emphasized its enhancement to orga nic - matter maturation and hydrocarbon generation in this paper 在分析、总结国内外一些含油气盆地的典型资料的基础上，论述了热流体活动的若干重要表现形式及主要研究方法，强调了热流体活动对有机质热演化和油气生成的强化作用。
There would be found distinct second " hardening apex in the curve when a conclusion was drawn that i : is likely that the most effective measurement to increase the strength and toughness is to fine grains and precipitate carbide nucleates of microalloyed elements , especially , fined grains of microalloyed elements increase the strength and toughness greatly 结论；综上所述，在一定的热处理工艺下，提高微合金化50crv钢强韧性的最有效的方法是细化晶粒和沉淀强化，特别是微合金元素的细化晶粒强化作用。
Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo , the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary , the coarser beo particles clustering on the grain boundaries results in negative influence on o mys 开创性地用预烧结? ?酸洗工艺制备了相同粒度、不同beo含量的铍粉，从而开展了beo含量单独对铍材_ ( mys )影响的研究，得出一些新的结果：与beo含量相比， beo在铍中的分布状态对_ ( mys )的影响更大。沿晶界、晶内弥散分布的较细小beo对基体铍有弥散强化作用，使_ ( mys )即较高；如果beo较粗大地成簇状聚集在晶界，反而对_ ( mys )有不良的影响。
In anchoring effect , in addition to the influence of high and low anchor points on subjects price estimates , we also consider the moderating role of the operation of anchor points ( one - way / two way ) , the reinforcement of anchor points ( normal / intensified ) , and the relevancy between anchor and target ( relevant / unrelevant ) 在定锚效应的实验中，除了考虑高低锚点值对受测者价格估计判断之影响，同时亦探讨锚点运作方式（双向单向） 、锚点强化作用（强化一般） 、以及锚点讯息与估计标的物之间的语意相关性（相关不相关）等三个变数，是否会扮演锚点类型对决策者估计影响之调节角色。
