Co-operative Research for Advanced Application of Far-Infrared Ray Ceramics to Comprehensive Fields

许多论文指出，一些现象是由远红外辐射引起的。而对高温地区的现象进行科学讨论的文献不多。另一方面，在室温范围内还没有科学的论述。在5 ~ 25 μ m的波长范围内测量了某些单晶氧化物的远红外特性。简单氧化晶体与氧化陶瓷之间的差异不大。针对卧式湿颗粒层红外辐照干燥过程，在考虑内加热的情况下，对其传热传质进行了理论分析。很明显，在干燥过程中，内部加热的效果是非常重要的。通过几种加热器在相同热流条件下对模型食品的加热实验，发现远红外波段发射率高的陶瓷加热器对食品表面的着色效果最好。通过对远红外（FIR）辐射对细菌损伤的影响与导热加热的影响进行比较，认为远红外（FIR）辐射对细菌的损伤是由热应力引起的。10种陶瓷粉对大肠杆菌和金黄色葡萄球菌的生长有抑制作用。氧化镁和氧化钙粉浆对细菌有一定的杀灭作用。氧化锌粉浆对细菌有抑菌作用。远红外辐射对离体大鼠下丘脑切片自发神经元活动无明显影响。据报道，远红外辐射的睡眠调节作用似乎不太可能与它对大脑的直接作用密切相关。通过对6名年轻男性穿着陶瓷复合腈纶（CER）等6种不同材质衬衫的体温调节功能的测量，发现穿着陶瓷复合腈纶（CER）等6种材质衬衫的皮肤血流量明显高于其他材质衬衫。红外线照射机体后，通过热像仪和^<133A>Xe清除率法观察体温升高和外周血循环压力。少

Many papers indicate that some phenomena are caused by the far-infrared irradiation. And only a few papers discuss the phenomena scientifically in the region of higher temperature. On the other hand, there are no paper which discuss it scientifically in the region of room temerature.The far-infrared properties on some single oxide-crystals were measured in the wavelength range of 5 mum to 25 mum. There were little discrepancy between simple oxida crystals and oxide-ceramics.For the drying process of horizontal wetted particle layr by infrared irradiation, the heat and mass transfer was theoretically analyzed with the consideration of internal heating.it became clear that the effect of internal heating is greatly concerned in the drying process.Based on heating experiments of model foods by some kinds of heaters under the same heat flux conditions, it became clear that the ceramics heaters with high emissivity in the region of far-infrared wavelength was most efficient for coloring the … More food surface.Based on comparing the effect of far-infrared(FIR)irradiation on bacteria injury with that of thermal conductive heating, it was suggested that the bacteria irradiated by FIR was injured by thermal stress.The growth of the test bacteria(Escherichia coli and Staphylococcus aureus)was inhibited by 10 ceramics powders.The Mgo and Cao powder slurries had the bactericidal action on the bacteria. The ZnO powder slurry had the bacteriostatic action the bacteria.Exposure to far infra-red radiation brought about no significant alteration in spontaneous neuronal activity of rat hypothalamic slice in vitro. It appears unlikely that the reported sleep-modulatory effect of far infra-red radiation is closely linked with its direct action on the brain.Based on the measurement of thermoregulatory function in six young male adults, who wore six kinds of shirts made of different materials including ceramics-compound acrylic fiber(CER), it was found that skin blood flow in wearing CER shirts was significantly higher than that in wearing the other kinds of shirts.As a result of infrared irradiation on the body, the elevation of temperature and peripheral circulation pressure were observed by the thermography and ^<133A>Xe clearance method.
