Off-axis aspherical mirrors are growing in popularity in modern space-borne cameras having high resolutionand large field of view. Fabrication processes for these mirrors include surface generation by grinding wheel, free-abrasive lapping, and various pol
We used Raman spectroscopy to study the conformational changes of DNA induced by Cd2 ions in different Cd2 concentrations solution. The experimental results show that when the Cd^(2 )/PO^(-)_(2) ratio R increased from 0 to 3.0, the band 835.0 cm^(-1) sh
