1.The curve of life is like the parabola of a projectile which, disturbed from its initial state of rest, rises and then returns to a state of repose.
2.By means of electromagnetic theory of light,this paper analyses the polarization state distribution of emergent light while the spherical wave front of the light is reflected by a Brewster polarizer. We find the device is not perfect,except in a special line.
3.A Littrow configuration ECL is designed, which features that the continuous tuning range is more than 3 GHz and the linewidth is less than 1 MHz.
4.A theoretical investigation of the noncollinear interaction between the magnetostatic forward volume wave(MSFVW) and optical guided wave(GOW). The frequency response curves of the diffraction efficiency of GOW have been computed for Bi?doped YIG?GGG and pure YIG?GGG waveguide.
5.Fluorescence spectrum of Nd∶GGG crystal was obtained under excitation with the 488 nm argon ion laser at room temperature with British fluorescence spectrometer,and the stimulated-emission cross-section is calculated to be 21.57×10~(-20)cm~2.
6.Results:The dose outputs and dose ditributions measured by SCD-61 diode developed by us were tested and verified by TLD dosemeter,and the results show tha there is a 5% consistency for the value at the focus point.
