- Study on analytic precision of laser microemission spectral analysis in argon atmosphere at reduced pressure
减压氩气环境下激光微区发射光谱分析精度的研究 - Ni3al has a good wettability with tic . in purified argon atmosphere , melt ni3al can infiltrate tic preforms spontaneously
Ni _ 3al熔体在氩气保护下，可以自发浸渗充满多孔tic预制体。 - Irradiation defects decompounded and recombined with oxygen impurity and large quantity of nucleation centers were introduced in czsi bulk during annealing at 1100 . in nitrogen atmosphere , more defects were induced in fast neutron irradiated czsi than in argon atmosphere
不同气氛下快中子辐照直拉硅中缺陷形成的差异很大， 1100的高温退火中，与氩气氛相比，氮气氛退火样品中出现了更多缺陷。 - In this paper , we reported the structural and luminescent properties of si - based oxide films containing semiconductor si , ge or metal al powders prepared by a dual - ion - beam co - sputtering method ( si - sio2 films and al - si - sio2 films ) or rf magnetron sputtering technique ( ge - sio2 films ) , and analyze the pl and el mechanism . 1 . the composite films of si - sio2 films were prepared by dual ion beam co - sputtering method from a composite target in argon atmosphere
我们利用双离子束共溅射和射频磁控共溅射技术制备了一系列含有半导体si 、 ge颗粒及金属颗粒al的薄膜，即si - sio _ 2薄膜、 ge - sio _ 2薄膜和al - si - sio _ 2薄膜，分别对它们的结构、光吸收以及发光性质进行了研究。 - The optimized experimental conditions are determined and the densities of some elements in the mental alloy standard samples are measured . the experimental results shows that the spectral intensity of the plasma enhances significantly with the increase of the operating voltage and the power density . ( 1 ) to the steel ally sample , the emission intensities of the spectra reach to the maximum values when the laser operating voltage is 1600v and the argon pressure is 600 torr . under the same pressure , the spectral intensity of the plasma in the argon atmosphere is stronger than that in the air . when the argon pressure is 320 to rr , the signal - noise ration is about 5 times than that which the argon pressure is 700 torr , but the temperature of plasma is less about 1000k
( 1 )对于光谱标钢准样品，当激光器工作电压为1600v 、氩气压力为600乇时，谱线强度达到最大，并且在相同压强下，氩气中的等离子体与空气中的等离子体相比，其辐射强度明显增强；氩气压力为320乇时的谱线信背比约为600乇条件下的5倍，而等离子体温度却下降了近1000k ，即等离子体温度随环境气压的增大而增大；当激光束的焦斑在样品表面上下移动时，激光诱导量、等离子体的激发温度、谱线强度都呈不对称性分布，其最大值对应的焦斑位置都位于样品表面之下0 . 4mm左右。
