    採取施加外部機械力、控制升降溫速率以及盡量降低焊接溫度或減少焊接時間（防止脆性金屬間化合物的過度增長）等措施，確保了焊接接頭的平整性和界面結構的完整性。建立起梯度飛片擊靶的理論模型，對93w - ofc - tc _ 4 - al - mb _ 2系波阻抗梯度飛片的擊靶過程進行了數值模擬計算。
  3. 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
  4. Because of rich labors and some other objective reasons in china, manual or semi - automation welding is used frequently. the manner makes workers tired because of heavy duties and long - time working, waste too many labors and is of low efficient

    我國由於勞動力充裕，以及一些客觀存在的原因，經常採用手工焊或半自動化焊接方式，但是這兩種焊接方式存在一些缺點:勞動時間長，勞動強度大，生產效率比較低，且浪費人力。
  5. The maximal power outputs of 37. 0 mw / cm2 and 30. 0 mw / cm2 for the p - and n - type laminated materials respectively at the temperature difference 490 have been experimentally obtained, which are about 2. 5 and 3. 0 times those of - fesi2. chemical analyses show that the interface failure between the bridge alloy and the semiconductor bi2te3 results mainly from the eutectic mixtures with low melting point and brittle compounds formed during welding and long time annealing at 190. it is found that the electrical properties of a laminated structure are mainly controlled by the wettability of the bridge alloy on the semiconductor surface

    發現： 1 ）疊層材料具有明顯優于均質材料的熱電性能，在490溫差下， p -型和n -型疊層材料的最大輸出功率分別達到37 . 0和30 . 0 （ mw / cm ~ 2 ） ，是同類型均質- fesi _ 2的2 . 5和3倍； 2 ）在焊接過程和190長時間退火處理過程中，焊接過渡層合金和基體半導體（特別是bi _ 2te _ 3 ）之間存在明顯的元素相互擴散，從而在過渡層中形成一些低熔點共晶體和脆性化合物，這是導致疊層材料破壞的主要原因； 3 ）焊接過渡層合金與半導體基體之間的潤濕性是影響界面層電性能的主要因素。
  6.
