The luminous transmittance of the DLC/Substrate was over than 90% (at visible light range) and the hardness of it was high (HV9 -11 GPa). Both the scratch resistance (19.6N load to the tool nose scratching on the DLC Films) and the ultraviolet irradiation resistance of the DLC films were excellent.
In this paper,the measurement results from the radiation force method are used as a reference. When the peak-to-peak drive voltage of the transducer is 120 V,average of the results obtained using the proposed method and the radiation force method are 5.09 W and 6.06 W,respectively,with a difference of 16%.
First the function and the using method of the SYSNOISE software is studied. Then the acoustic radiated field and the radiation impedance of several typical sources are calculated by using the boundary element method, and the results are compared to the analytic solutions.
At last we study the radiation characteristic of the Mo/Si multilayer mirror, measure the mirror’s reflectivity before and after electron and proton irradiation, the experimental results indicate that the reflectivity of the Mo/Si multilayer mirror reduce by 1%~3% after high energy electron irradiation, the wavelength corresponding to peak reflectivity changes by 0.3nm. ;
