So far, we human beings for the heating of the concept has long been restricted to convection, conduction, radiation three kinds of surface heating in it, in recent years the use of molecular friction between the object itself is heated and heat of the principle of the developed in the dielectric heating (including the high-frequency and microwave heating) has been widely used in industrial heating and drying purposes above, this heating method unlike the aforementioned three kinds of methods, the heat do not penetrate the surface, but will wear the electromagnetic energy directly to transparent objects into heat inside a method, also known as the fourth heating methods
到目前为止,我们人类对于加热之观念一直都被局限于&对流&、&传导&、&幅射&三种表面加热方法而已,近年来利用&被加热物体本身分子磨擦生热之原理&所发展出来之诱电加热被广泛应用于工业加热干燥用途上面,此种加热方法不像前述之三种方法,热量不需要穿透物体表面,而是将电磁波能量直接穿透物体内部转换成热量的一种方法,也被称为第四种加热方式

In chapter 2 and 3, experimentally, using the Angular-Resolved high-resolution fast Electron Energy Loss Spectrometer , at the condition of 2. 5 keV incident energy and 50-60 meV energy resolution, we measured the Optical Oscillator Strength Density Spectra for the excitations of 4p, 4s or 3d electron. The oscillator strengths for excitations of the valent shell 4p electron were obtained, and comparisons were done between presently experimental and previously experimental and theoretical results. The experimental results of different groups agree with each other approximately, but the semi-experientially theoretical results do not match with the experimental results. The delayed maximum in the photoabsorption spectra was discussed. It should arise from the transition of 4p→∈d. For the excitation of the inner-valent 4s electron, the discrepancies for the resonant structures in previous electron-impact results and photoionization results were clarified in present work, which confirms again that the fast electron impact method is suitable to measure the optical oscillator strengths. The autoionization Rydberg series 4s〓ns (n=5, 6, 7) and 4s〓nd (n=4, 5, 6, 7) were identified without ambiguity by the measurement at 0°, 2° and 4°scattering angles. The energy levels and natural widths of the excitations of Kr3d and Ar2p inner shell, including optically allowed and forbidden transitions, were determined. The widths of these inner shell excitations are nearly the same, which was interpreted by the Resonant Auger effect .
