The results show that the higher is electron density distribution , the effect is more evident . so the gradient effect must be included to measure higher density plasma in experiment 结果表明,在等离子体电子密度分布较高区域,梯度效应明显,指出在实验上测量高密度等离子体密度时必须考虑梯度效应的影响。
The technology renovation project " application of frequency sweep microwave interferometer method to the measurement of electron densities in the wake of hypervelocity projectiles " is the research work of this thesis 具体要求是将所研制的扫频式微波干涉仪应用于某气动物理靶中对等离子体尾迹进行电子密度的测量。
According to the fringe shift of the interferograms , electron density and implosion velocity can be obtained . in the early period of plasma imploding , the averaged electron density is , 在箍缩早期平均电子密度为,运动速度为;聚焦附近,等离子体的平均电子密度约为,运动速度,最小箍缩半径0 . 49mm ;崩溃阶段,等离子体的崩溃速度为。
At the same time , the paper give out the investigation of x - ray interferometry in diagnostics of the electron density of laser produced plasma , and derived a modified term for wkbj solutions . at last , we proved these by numerical simulation 接着,本文给出了x射线激光干涉法在激光等离子体电子密度诊断中的理论研究,给出了对原有干涉法理论修正,并用数值计算中加以了验证。
The output spot - size of our non - flowing tea co2 laser is quite large , only slightly smaller than the section of the excited media , this agrees with the calculated spatial distributions of the initial electron density for pre - ionization well 由我们的非流动型teaco _ 2激光器获得的输出光斑相当大,仅比激活区截面略小,这与理论计算的预电离初始电子密度空间分布规律有较好的一致性。
