项目摘要
1) Effect of gas inclusion on stable operation region of pulse-modulated induction thermal plasmaStable operation region of pulse-modulated induction thermal plasma(PMITP) highly depends on added gas, which is related to plasma-quenching ability of gases. In order to investigate plasma-quenching ability of various gases, Four kinds of environmentally-benign gases such as N_2, H_2, Q_2 and CO_2 was injected into Ar PMITP. The results indicates that inclusion of CO_2 decays drastically the stable operation region of PMITP. This means that CO_2 has a higher plasma-quenching ability compared with the other gases treated in the experiment.2) Effect of gas inclusion on transient behavior of pulse-modulated induction thermal plasmaGas inclusion affect transient behavior of PMITP, which is also markedly related with plasma-quenching ability of gases. We measured time evolution of radiation intensity of Ar line emitted from PMITP with added gases. As a result, CO_2 inclusion made transient behavior of PMITP delayed. This also indicates that CO_2 has high plasma-quenching ability.3) Effect of gas inclusion on time variation in Ar excitation temperatureThe time-resolved radiation intensity measurement permitted us to estimate Ar excitation temperature of PMITP. Two-line method of Ar spectral line was used for this temperature estimation. The results revealed that CO_2 inclusions decayed Ar excitation temperature markedly compared with the other gases.4) Temperature measurement of laser-induced plasmaIn order to study the dielectric strength of high-temperature gas, laser-induced plasma technique was adopted. Temperature was evaluated from Boltzmann plot method on the assumption of local thermal equilibrium. From the result, laser-induced plasma temperature can be estimated.
1)脉冲调制感应热等离子体(PMITP)的稳定工作区高度依赖于外加气体,这与气体的等离子体淬灭能力有关。为了研究不同气体对等离子体的猝灭能力,在Ar PMITP中注入了N_2、H_2、Q_2和CO_2四种环境友好气体。结果表明,CO_2的加入使PMITP的稳定运行区域急剧衰减。这说明CO_2具有更强的等离子体猝灭能力。2)气体夹杂对脉冲调制感应热等离子体瞬态行为的影响气体夹杂对PMITP的瞬态行为有影响,并与气体的猝灭能力密切相关。我们测量了PMITP中Ar线辐射强度随时间的变化。结果表明,CO_2包裹使PMITP的瞬态行为延迟。这也表明CO_2具有较高的等离子体猝灭能力。3)气体包裹体对Ar激发温度随时间变化的影响时间分辨辐射强度测量使我们能够估计PMITP的Ar激发温度。Ar谱线的双线法用于该温度估计。结果表明,与其它气体相比,CO_2包裹体对Ar的激发温度衰减明显。4)激光诱导等离子体的温度测量为了研究高温气体的介电强度,采用了激光诱导等离子体技术。在局部热平衡的假设下,从玻尔兹曼图方法评估温度。根据计算结果,可以估算激光诱导等离子体的温度。
