The increase in refractoriness referred to here is usually termed freezing. The study was undertaken to overcome the tendency of pyrometric cones to set or freeze when subjected to prolonged heat treatment when the temperature is more or less fluctuating. The work includes a study of the freezing tendency of some natural clays, of several pottery bodies, and of pyrometric cones. A body was developed that does not freeze under the treatment that produces the phenomenon in the other materials tested but the cause is not established. 相似文献

介绍了美国近年来在水泥应用方面的研究动态。其基本方针是从材料科学,尤其是脆性材料理论出发,通过改变水泥基材料的组成和改进成型方法,使硬化水泥石的结构趋于合理,从而大幅度提高水泥的各种性能,最终达到部分取代陶瓷、金属、塑料和木材等其它材料的目的。这种新型的水泥材料被称为ACBM(Advanced Cement Based Materials)。美国已建立了ACBM研究中心,并出版了名为“Cementing The Future”的专门刊物来介绍这方面的科技新信息。 相似文献

Abstract Moisture distribution in spheres of potato (Solanum tuberosum) and yam (Dioscorea japonica) tubers during microwave drying was investigated. Moisture variation at various locations within the samples was experimentally determined for different drying times. A numerical simulation model was developed based on a modified form of Lambert's law for microwave penetration in spheres and on moisture transfer in both liquid and vapor phases. This model was used to study various factors influencing moisture distribution. Moisture profile during microwave drying was strongly influenced by non-uniform microwave energy distribution within the foods. The core moisture contents were lower than other parts of potato and yam spheres of the various sizes tested in this study (2.6 cm to 6.0 cm diameter). The sphere radius to microwave penetration ratio (2αro) was an important parameter affecting the moisture profile in spherical foods. For 2αro of less than 2.0, the moisture content in the center of potato and yam spheres was markedly lower than the rest of the food, but for 2αro between 2.5 and 4, moisture contents at the center and close to the surface were lower than the average moisture content. 相似文献

Research and development of drying processes and equipmect has a long tradition in Czechoslovakia (1). There are at least 10 top reoearch centers where drying of varicus materials has been studied. Remarkable attention to drying theory and application is also paid at Czechoslovak universities which yields numerous theses dealing with various aspects of the drying process. The total of 52 M.Sc. theses oriented to drying and/or dryers had been published in the last decade. Moreover, 22 Ph.D. theses were carried out in the same period. This represents an important source of theoretical and experimental results. However all theses had been mitten in the Czech or Slovak language, and therefore their wide international application is rather limited. They are summari-zed in the following list. 相似文献
