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 -

On the basis of detailed investigation concerning the constant changes and the characteristic of farmers " incomes of ningxia from the year 1978 to 2002, as well as a deep analysis of reasons about slowly - growth of farmers " income and the facts which effect the increasing of farmers " income by using the date and regression analysis, this thesis holds a view that there are many facts that cause the difficult growth of farmers " incomes, we must give prominence to the principal contradiction, for examples, adjusting agricultural structure, transferring surplus labor forces in rural areas, developing second and third industry, improving farmers " quality, reducing farmers " burdens, and so on. this paper consists of five sectors : section one : describing the feature of farmers " income change of ningxia
第四部分，在分析寧夏農民收入變化的基本特徵以及影響農民收入增長的主要因素的基礎上，提出了當前農民增收面臨的主要矛盾，即：糧食等主要農產品的供求矛盾、小生產與大市場的矛盾、勞動力的充分供給與就業能力不足的矛盾、城鄉二元經濟結構的矛盾；農產品價格的提高對增加農民收入的作用越來越小、農業生產結構調整滯後於食品消費結構的變化，農民增產不增收、農村滯留的勞動力越來越多，難以實現規模經營、鄉鎮企業吸納農村剩餘勞動力的能力下降，使農民非農業收入減少。
