Abstract:
AGE方法是一种求解偏微分方程的并行算法,通过重新构造有限差分格式,把所要求解的差分方程组分裂成若干个可以独立并行求解的规模较小的方程组。但此种算法在靠近边值处误差较高,本文在靠近左右边界处对格式进行改进,得到一种在边值处改进的AGE方法。该方法在边界附近尽可能的保持较小的截断误差,从而提高了计算精度。
AGE method is a parallel algorithm for solving partial differential equations, by re-construct a finite difference scheme, so the required solution of difference equations can be split into several smaller inde-pendent parallel solution of equations. However, this algorithm gets higher truncation errors near the boun-dary. In this paper, I get an improvement AGE method, by improving the format close to the left and right boundaries. The method stays as smaller truncation errors in border, so can improve the calculation ac-curacy.

Abstract: 研制了新型消声器材质,并结合数值模拟、工业测试等对以新型材料为主材料的消声器的空气动力性、适用性进行了研究。研究结果表明(1)以改良型类似于玻璃钢新型材料为主材料的消声器具有防腐、质量轻的特点,同时吸音效果较好;(2)通过ANSYS软件对能量转换型消声器内部流场的流体流动进行数值模拟,得出气流通过消声器时,动压会减少,静压会增加,但动压减少量不等于静压增加量,在消声器几何尺寸不变情况下,速度越大,消声器压力损失量越大,消声器的阻力损失随着穿孔率的增大而增加;(3)该种消声器的安装对于风机正常运转影响极小,但降噪效果显著,具有较大的社会经济效益。研究成果对于矿用风机噪声控制具有重大意义。

Abstract:
煤炭产业链延伸是增加产业附加值,实现产业优化的过程。在确定煤炭产业链合理延伸路径之前,需要全面、客观地分析煤炭产业链的内外部影响因素,才能确保产业链延伸的社会、技术和经济效益。本文通过构建影响煤炭产业链延伸的内部外各个影响因素,进而构建基于GEM的双因素评价模型,来评判各个影响因素对煤炭产业链延伸的重要性,最终确定影响因素的整体作用对于煤炭产业链的延伸到底是有促进作用还是阻碍作用,将为煤炭产业链延伸起到决策支持作用。
The coal industry chain extension process is to increase the industrial value-added, industrial op-timization process. In determining the path of a logical extension of the coal industry chain, we need a com-prehensive, objective analysis of the coal industry chain, internal and external factors, in order to ensure that the chain extension of the social, technological and economic benefits. This paper has research various inter-nal and external impacting factors chain on the coal industry chain extension, and then has build a GEM- based two-factor evaluation model to judge the impact of various factors on the importance of the coal indus-try chain extension, and ultimately determining the overall impact of factors affecting the coal industry chain for extension in the end which is a key factor in promoting or inhibiting. It will play a key role in decision support for the coal industry chain extension.

In this paper, four methods including entropy sequence, logarithmic series, time series, and standard deviation series based on the PCNN have been introduced to extract the features of face orientations. It is able to achieve the transform from multi-dimensional information to one-dimensional information. The classified results of loga-rithmic series which are impacted by salt & pepper have been analyzed. The method of Euclidean distance has been used to classify and recognize the face orientations. The results prove that the method based on logarithmic series whose accurate identification rate was 96% has certain antinoise ability.

Abstract: 水库调度图作为指导水电站安全高效运行的依据,一直是水库调度研究的热点,然而现有研究大多以单库调度图为对象进行优化,或是基于中长期发电优化调度模型绘制梯级水库调度图。单库优化调度图较难满足梯级调度要求,而后者虽然理论成熟、应用广泛,但存在建模、求解复杂,步骤繁琐,误差较大等的缺点。鉴此,本文提出了一种采用模拟与优化相结合的技术绘制梯级水库优化调度图的实用方法。该法通过直接优化梯级水库常规调度图的调度线,从而获得优化调度图。以乌江流域4座调节性能较好的水库构成的梯级水库为研究对象进行实例分析,模拟调度结果表明较大地提高了梯级长期发电效益,验证了该法的可靠性和有效性,从而为梯级水库优化调度图的绘制提供了新思路。
Reservoir operation chart has been a hot topic of the reservoir operation study as a basis for the guidance of the efficient and safe operation of the hydropower station. However, existing studies are mostly studying on the optimizing drawing of single reservoir, or research on the drawing of cascade reservoirs operation chart using a long-term power optimization scheduling model. Single reservoir optimized operation chart is hard to meet the cascade scheduling requirements, while the latter theory is mature, widely used, but has its flaws. For this, this paper puts forward a drawing way of cascade reservoirs optimal operation charts, using the combination technology of simulation and optimization, through the direct optimization of the cascade reservoirs conventional operation curves. For the cascade hydropower stations on the WujiangRiver, simulation scheduling results show considerably increase on the cascade long-term generation benefit. Thus verify the reliability and validity of the method, so as to provide a new idea to draw the cascade reservoirs operation chart.

Abstract: 姓名字母效应表现为个人对于自己名字的组成字符有着相对于其他字符的偏好,反映了个体对于自我以及和自我有关的事物的内隐积极态度,常被作为考察内隐自尊的一个重要指标。文章介绍了姓名字母效应的研究程序与记分方法、以姓名字母偏好任务研究内隐自尊的有关发现以及姓名字母效应对于实际生活决策和任务成绩的影响,并在展望部分提出了需要进一步研究的问题及在中文语境下研究姓名字母效应的可行性。
Name-letter effect refers to the phenomenon that people evaluate the letters in their own names more favorably than letters that are not in their own names. It reflects an implicit positive attitude towards the self and self-related objects, thus, it can be used as an index of implicit self-esteem. The current paper introduced the procedures and scoring methods for name-letter effect, findings of using name-letter task, as well as its implications in life decisions and task performances. Two issues that remain for future research and the feasibility of studying name-letter effect in Chinese context were discussed.
