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

许多文献指出，有些现象是由远红外辐射引起的。科学地讨论高温地区的这一现象的论文很少。另一方面，在室温范围内还没有对其进行科学讨论的论文。在5~25微米的波长范围内，测量了一些氧化物单晶的远红外特性。对于水平润湿颗粒层的红外辐射干燥过程，考虑了内部加热的影响，从理论上分析了干燥过程中内部加热的影响。通过在相同热流条件下用几种加热器对模型食品进行加热实验，发现在远红外波段高发射率的陶瓷加热器对…的着色效果最好通过比较远红外(FIR)照射和热导加热对细菌损伤的影响，认为FIR照射的细菌是热应激损伤的，10种陶瓷粉末对受试菌(大肠杆菌和金黄色葡萄球菌)的生长有抑制作用，氧化镁和氧化钙粉末浆液对细菌有杀菌作用。氧化锌粉浆对细菌有抑菌作用，远红外照射对大鼠下丘脑脑片自发神经元活动无明显影响。远红外线对睡眠的调节作用似乎不太可能与其对大脑的直接作用密切相关。根据对6名年轻男性成年人体温调节功能的测量，他们穿着6种不同材料的衬衫，其中包括陶瓷复合腈纶(CER)，发现穿CER衬衫的皮肤血流量明显高于穿其他类型衬衫的人。由于红外辐射对人体的照射，通过热像仪和133a；Xe清除法观察到温度和周围循环压力的升高。较少

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.
