  2. The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased

    本文利用數值模擬手段對轉輪的焊接工藝從分段焊和局部加熱兩個方面進行了優化,結果表明:採用普通工藝焊接時,葉片焊后殘余拉應力出現在焊縫及其附近區域,並且在葉片出水邊的熔合線附近(危險區域)出現了峰值;在採用優化的分段焊時,先焊兩端后焊中間的方法可以降低葉片危險區域的焊接殘余拉應力峰值,降低效果與葉片出水邊焊段長度、焊縫各段的焊接方向有關;局部加熱法降低轉輪危險區域殘余應力的效果主要與加熱時間、加熱溫度以及加熱面積成正比,與冷卻面積成反比,並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。

  6. This paper describes a reconstructive algorithm which is based on network theory for electrical capacitance tomography technic. there are twelve electrodes in the system. the permittivity distribution of flow with two components within a pipeline is reconstructed. assume the permittivity distribution of the region to be reconstructed. then whole measured area is discretized into a network composed of capacitance. the measurement circuit which contains a pair of source electrode and detecting electrode is taken as a four - terminal network. the across admittance of the four - teminal network is proportional to the capacitance between the source electrode and the detecting electrode. modify the distribution of the permittivity according to the difference between the calculated capacitance and measured capacitance. the experimental results show that this algorithm is effective and can coverge

    本文描述了一種用於兩種成份的流體成像的12電極電容層析成像新方法.該方法基於電路的網路理論,首先對重建區域假定一個介電率分佈,用電容網路作為離散化模型,將每一個源電極和探測電極對組成的測量電路看作一個四端網路,該四端網路的跨導與源電極和探測電極之間的電容值是線性關系,這個電容值和測量得到的電容值之間存在誤差,根據這個誤差對修正介電率分佈.通過對不同介質分佈作的模擬實驗結果,證實了該演算法是有效的,收斂的
