A tunable TEA CO_2 laser is used to separate D2 by multiphoton dissociation of CF_3H. The enrichment coeff cient is obtained up to 1.2x10~ 4 determined by gas chromatography. 用调谐TEACO2激光多光子离解CF3H分离氘同位素,用气相色谱法确定氘的浓缩系数为1.2×10~4。
When the vibrator is in the resonance state, the ratio of moving friction coeff cient to static one will decrease to-0.1. The driving voltage of position-gripped vibrator is only ± 80V ( Vp-p). 振子共振时其动摩擦系数与静摩擦系数之比降为~0.1。箝位振子的激励电压仅为±80V(峰峰值)。
