作为人类社会一种独特的文化形态,体育运动具有除健身本质功能之外多方面的价值,美学价值就是其中比较具有代表性的一种.体育运动的美有诸多方面的表现,如形体美、技术美、战术美、精神美、悬念美、心灵美等.该研究通过深入发掘体育的美学价值,将之与陶瓷专业高等教育有机结合,证明体育之美有利于活跃学生的创作思维,能够启发学生更丰富的创作灵感,帮助学生创作出更多具有体育美学特征的优秀的陶瓷艺术作品.由此可见,体育教育并非高等学校中的一般教育,高等学校应注重发掘体育教育的多方面价值,并与高等专业教育有机结合起来,促进高等学校专业教育的发展. 相似文献

高速角接触陶瓷球轴承动态特性研究 总被引：3，自引：0，他引：3
根据滚动轴承的分析理论建立了轴承的动态数学模型并通过Hook-Jeeves的优化方法求解，研究了高速角接触陶瓷球轴承的动态特性，并与传统的钢轴承作了对比．结果表明：与低转速工况时相比，高转速时轴承的动态性能不仅受预加载荷的影响，而且在更大程度上与转速和滚珠材料特性有关：随转速的升高，轴承的轴向刚度与径向刚度均发生显变化，变化趋势为先下降后上升；在高速状态下，与传统钢轴承相比，陶瓷球轴承的接触应力及变形明显降低、接触角变化较小、轴向与径向刚度变化程度相对较低、动态特性相对稳定，从而具有传统钢球轴承无可比拟的优越性． 相似文献

陶寺陶板边缘均整齐平直,没有瓦沟疏导雨水,不可能作为板瓦使用;陶板的厚度多在1~2厘米之间,厚度不能满足地板砖承重的需要,不能作为地板砖使用。陶板所在出土单位出土了烟囱、陶水管、灶块等厨房建材,因此陶板可能是厨房用砖。 相似文献

对一特殊扇形陶瓷件的传动定位方式及夹具进行研究,设计蜗杆传动和圆弧导轨传动相结合的传动定位平台与活动扒爪的夹紧机构,通过对活动扒爪机构的受力分析,计算得到其运动的临界压力角,不仅使刀具在铣削过程中与装夹机构不发生干涉,而且为加工扇形陶瓷件提供所需夹紧力。从而简化运动定位方式,降低成本,提高陶瓷件的加工精度等。对后期具体设计制作具有很强的工程实用价值。 相似文献

This paper deals with the comparative evaluation of different procedures of salt extraction designed for archaeological ceramics from submarine burial environments. The experimental work was carried out on a particular type of late-Roman cooking ware finds (Pantellerian ware) found in a shipwreck near the shoreline of the Island of Pantelleria (Sicily). The studied ceramic test-pieces were first recognised in terms of bulk characteristics (mineralogy, petrography and chemistry). SEM-EDS observation allowed verification of the presence of various secondary minerals at the surface and in the pore spaces formed after the prolonged permanence in seawater under oxidising or reducing conditions. Pore-size distribution was also determined in the same fragments that had been subjected to the salt extraction routines. Three salt extraction methods were tested: two methods based on diffusion processes (water immersion under stationary conditions and under mechanical stirring conditions) and one method based on both diffusive and advective processes (multiple packages of sepiolite). The obtained experimental data allowed us to identify strengths and weaknesses of the tested procedures with practical spin-off for archaeologists and restorers (efficiency, kinetics, compatibility with the ceramic substrate, costs and simplicity of use). Salt extraction under mechanical stirring was the most effective method and, for this reason, is suitable for laboratory fieldwork during or immediately after submarine archaeological excavations. Similar advantages are also intended for the preliminary treatments of the most precious findings prior to museum storage. 相似文献

薄膜制备过程中溅射靶材的利用率很低,导致薄膜材料制备成本很高。以自制的高纯度纳米晶镍锌钴/二氧化硅复合铁氧体粉体为原料,冷等静压后高温烧结制备得到铁氧体复合靶材。用XRD、EPMA和SEM分析靶材的化学成分和微观形貌。结果表明:靶材为镍锌钴铁氧体和二氧化硅的复合材料,收缩率达14.37%,能在高真空多功能磁控溅射仪正常工作,并成功制备得到性能良好的软磁薄膜。整个制备过程工艺简单,操作方便可行,大大降低了靶材的制备成本。 相似文献

INTRODUCTION In powder compaction, the characteristics ofthe powder affect the compaction behavior and thequality of the pressed green body and its relativedensity, porosity, pore size distribution, sinteringand the consequent microstructure of the final sin-tered body. Superfine powder is prerequisite forpreparing high performance ceramic materials (Liu,1996; Lange et al., 1983; Lange, 1989). At present,most of the chemosynthesis methods are not suit-able for preparing industrial … 相似文献

Preparation of high performance ceramic tiles using waste tile granules and ceramic polishing powder 总被引：1，自引：0，他引：1
This paper presents an innovative approach to reusing waste tile granules （TG） and ceramic polishing powder （PP） to produce high performance ceramic tiles. We studied formulations each with a TG mass fraction of 25.0% and a different PP mass fraction between 1.0% and 7.0%. The formulations included a small amount of borax additive of a mass fracton between 0.2% and 1.2%. The effects of these industrial by-products on compressive strength, water absorption and microstructure of the new ceramic tiles were investigated. The results indicate that the compressive strength decreases and water absorption increases when TG with a mass fraction of 25.0% are added. Improvement of the compressive strength may be achieved when TG （up to 25.0%） and PP （up to 2.0%） are both used at the same time. In particular, the compressive strength improvement can be maximized and water absorption reduced when a borax additive of up to 0.5% is used as a flux. Scanning electron microscopy reveals that a certain amount of fine PP granules and a high content of fluxing oxides from borax avail the formation of glassy phase that fills up the pores in the new ceramic tiles, resulting in a dense product with high compressive strength and low water absorption. 相似文献
