欧亚草原腹地作为连接东西方文明的陆地走廊,不仅汇集了农耕、绿洲型社会的民间文学精粹,还孕育出游牧人群多彩纷呈的口头传统。在漫长的历史进程中,相较于书写体系完善的前者而言,草原游牧人群的历史、文化及民俗等人文知识的交流与传递则主要通过口头形式完成。阿肯阿依特斯是活态流传于中国、哈萨克斯坦以及蒙古国哈萨克族民间的一种即兴口头对唱艺术,它是集歌手(阿肯)的即兴创编、音乐天赋、雄辩口才等多重技艺于一身,融合了歌谣、谜语、传说等多种口头文学体裁特征的综合性口头艺术,也被称为“语词的竞技”。相较于史诗、神话、民间故事等口头文学体裁,阿肯阿依特斯的交流属性更为显著,这种交流属性既体现于表演场域,也体现在演唱文本创编的全过程。阿肯阿依特斯作为以交流为中心的民俗事件,在活态表演语境下探讨其表演场域和文本创编中的交互特点,挖掘阿肯阿依特斯作为“语词的竞技”之本真属性,突破既有以文本内容和修辞手段为对象的研究范式,对于深入理解和研究东西方口头对唱艺术而言,具有一定的前沿性和创新性。

Biodiesel is one of the most popular prospective alternative fuels and can be obtained from a variety of sources. Waste frying oil is one such source along with the various raw vegetable oils. However, some specific technical treatments are required to improve certain fuel properties such as viscosity and calorific value of the biodiesel being obtained from waste cooking oil methyl ester （WCOME）. Various treatments are applied depending on the source and therefore the composition of the cooking oil. This research investigated the performance of WCOME as an alternative biofuel in a four-stroke direct injection diesel engine. An 8-mode test was undertaken with diesel fuel and five WCOME blends. The best compromise blend in terms of performance and emissions was identified. Results showed that energy utilization factors of the blends were similar within the range of the operational parameters （speed, load and WCOME content）. Increasing biodiesel content produced slightly more smoke and nOx for a great majority of test points, while the CO and THC emissions were lower.

The paper deals with the non-local modification of kinetic Smoluchowski equation for binary coagulation. The main goal of the work is to remove the certain supposition inherent in the known kinetic equations of aggregation. This supposition consists in that speed of evolution of certain order clusters is usually supposed to be a function of the product of concentrations of the lowest orders clusters during the same moment. However, it stands for instant formation of the cluster at the moment of interaction of its components. The new form of kinetic equation for aggregation is derived on the base of the transfer kernels approach presented in our previous works. This approach allows considering the influence of relaxation times hierarchy on kinetics of aggregation process. Some results of the theoretical analysis and numerical experiments according to the model are submitted too.

乒乓球运动集健身、竞技、娱乐为一体,具有球体小、速度快、变化多、设备简单、趣味性强、不受参与人群年龄和性别限制的特点,因此,哈萨克斯坦共和国教育部门已将乒乓球运动列入了教育计划,大力发展乒乓球运动。本文以哈萨克斯坦共和国阿拉木图市为例探寻哈萨克斯坦共和国发展乒乓球项目存在客观制约因素,同时以哈萨克斯坦具体的体育政策为依据,找出影响哈萨克斯坦乒乓球项目发展的因素,对哈萨克斯坦乒乓球项目的发展现状进行一个客观的评价与分析。本研究采用文献资料法、问卷调查法、专家访谈法等研究方法,以体育专家、乒乓球教练员,乒乓球练习者为研究对象,发放了3类问卷,共发放了122份,回收122份,无效问卷0份,实收问卷120份,问卷的有效回收率达到100%,完全够满足研究的要求。通过研究发现,哈萨克斯坦乒乓球项目虽然发展潜力巨大,但是民众对乒乓球的认识并不积极,哈萨克斯坦政府部门对乒乓球项目的扶持力度较小,乒乓球俱乐部设施简陋,学员不稳定,教练员执教水平有待提高。

比较了未再结晶和再结晶Ti12Mo5Ta合金、未再结晶Ti12Mo合金和工业用纯钛(cp-Ti)在0.9%生理盐水(pH 2.3)中37°C下的电化学行为。从阳极极化曲线中得到了极低的钝化电流密度(10-6 A/cm2),这表明所有样品在酸性0.9%naCl溶液中具有高的耐蚀性能。采用扫描电子显微镜(SEM)观察样品的表面形貌,发现所有样品表面受到了相同的腐蚀,而且经阳极动电位极化测试后的样品表面没有出现点蚀、裂纹或其它缺陷。使用等效电路模拟电化学阻抗谱(EIS)数据,以表征样品表面且更好地理解Mo和Ta的添加对cp-Ti及再结晶的影响。EIS结果证实,在开路电位下,所有样品在0.9%naCl溶液(pH 2.3)中产生钝化(极化电阻约为105Ω·cm2)。在37°C时,样品在0.9%naCl溶液中(pH 2.3)的耐蚀性顺序为:再结晶Ti12Mo5Ta>未再结晶Ti12Mo5Ta>未再结晶Ti12Mo>cp-Ti。
