Combining the experimental results and theoretical analysis, the following work has been accomplished.(1) Reasons of the decrease of interelectrode capacitance and the increase of discharge gap caused by the powder suspended in dielectric fluid are explained. And the mechanism that surface quality of workpiece improved by powder-mixed EDM is analyzed from this viewpoint.(2) The variation regularity of the percentage of silicon on the machined surface of workpiece has been summarized according to the experiment results when silicon powder was added into the working fluid. The entropy is introduced to explain the reasons for this variation regularity by thermodynamics.(3) The dimensional accuracy is greatly influenced by the overcut resulting from discharge gap and electrode wear in practice application. Empirical formulas for the overcut in EDM and powder-mixed EDM are established based on the experimental results using the ternary linear regressive method in this paper.(4) The influence of main factors on the machined surface characteristics has been evaluated based on the orthogonal experimental design method.

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.

In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

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 .
