縫后域 的英文怎麼說
中文拼音 [fénghòuyù]
縫后域
英文
sutural area-
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。Profile curves of a rounding surface are calculated along a feature line with a given radius. then inner elements of a rounding mesh is created with these profile curves, and sewn with the original mesh which is pre - trimmed. a feature - based mesh modification method is proposed for existing rounding feature
給定圓角半徑，計算出沿特徵線圓角曲面的截面輪廓線，以輪廓線的六等分點為節點生成圓角區域單元，並與剪裁后的基網格面縫合，從而生成沿特徵線的圓角曲面網格。The study shows that the mud fracture in overpressure zone and lithologic reservoir should be the target domains for petroleum exploration
研究認為，超壓帶泥巖裂縫、巖性油氣藏將是令后的重要勘探領域。At the back focal plane of the objective, the blue wavelengths from each slit interfere constructively to produce the blue area of the diffracted image of each spectrum or order ; similarly for the red and green areas ( figure 4 ( a ) )
在物鏡的后焦面，從各個窄縫發出的藍色波長光產生增強干涉而產生各級的衍射圖像的藍色區域，紅色波長和綠色波長也一樣（圖4 （ a ） ） 。分享友人
