Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead
通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點，發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下，通過調節焊接迴路中的電感量和電源電壓，可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行，並且熄弧時間最短時，短路過渡頻率最高，在這種情況下，飛濺小，焊道成型好，焊接過程穩定 -

The incorporation of moderate contents of transitional metal ions at the sites of mg2 ions in
6siozm青石同溶體紅外輻射性能的影響。 -
The influence of the transitional metal ion, fe3 + and zn2 +, was discussed. fe dopent can be easily put into the matrix of tio2 and hardly inflects the crystal structure or surface morphology. it can decrease the band gap of the thin film effectively so that it will improve the hydrophilicity of the thin film
Fe ~ （ 3 + ）摻雜離子的引入能夠有效降低薄膜的光學能隙，提高薄膜的光響應范圍，從而使薄膜的親水性能提高；而zn ~ （ 2 + ）摻雜對薄浙往大』于傾卜、瀏億論文膜的親水性能沒有改善。
