Anode plasma structure in a gas discharge with neutral density depleted by ionization
      
It is found that, at a sufficiently high density of neutrals, the rate at which the atomic states are populated through charge exchange becomes independent of the neutral density, which results in the saturation of the spectral line intensities.
      
The results obtained confirm the possibility of reliable measurements of the hydrogen neutral density in the range 108-109 cm-3 in tokamak plasmas.
      
part A, the neutral density surface (the 'mcdougall surface') as a study fr

A wind shear profile as high as 330s-1 at 87.4km was measured by a Chaff rocket. TIs wind shear is believed to be the largest value ever measured in the mesosphere. Spectrum of the vertical velocity fluctuations in the extremely large shear layer has spectral slopes of -3.10, -1.65 and -7.11 in the buoyancy subrange, the inertial subrange, and the viscous subrange respectively. ms observation is in good agreement with the neutral density fluctuations. While the calculated inner scale and buoyancy scale do not agree with the breakpoints in the spectrum of the vertical velocity fluctuations. ms result is not consistent with the neutral density fluctuations. The relationship between turbulence and gravity wave is studied. This result suggests that enhanced turbulence is linked well with wave field saturation.

一枚Chaff火箭在87.4km高度测量到高达0.33s-1的风切变剖面,相信这个切变值是中层大气曾经测量到的最大切变值.在这个异常大风切变层内,垂直速度扰动谱在浮力子区,惯性子区,和粘性子区有谱斜率-3.10,-1.65,和-7.11,这个观测与中性密度扰动一致.计算的内尺度和浮力尺度与扰动谱中的崩溃点不一致,这个结果与中性密度扰动不一致.讨论了湍流和重力波之间的关系,结果表明,增强湍流与波场饱和有好的联系.

The passive visual sensing method was successfully applied to detect the image of weld pool in CO2 welding.In order to reduce the disturbance from the arc and acquire clear image of the weld pool,the composite filter system,which compose of narrow band filter,neutral filter and ordinary welding filter was designed.Firstly,the central wavelength of spectral window of narrow band filter was identified at 632.8 nm by analyzing the CO2 arc light spectrum distribution.Secondly,the best sequence of each filter in composite filter system was confirmed by experiments.The result of weld pool detecting indicated that the disturbance from arc could be effectively reduced by the composite filter system,and the high quality of images were received.At the end,the features of CO2 weld pool image were preliminary analyzed.The foundation of the future research of weld pool image processing and weld bead control was established.
