branching channel
解釋
辮狀河-
For the low water head water control project at a branching channel, its flood discharge capacity is related not only with the total discharge width but also with the discharge width ratio of the two branches
摘要位於分汊河段的低水頭樞紐，其泄洪能力不僅與樞紐的總泄流寬度有關，而且與兩汊泄流寬度之比有關。 -
A 2 - d hydrodynamic - numerical model was applied to typical rocky rapids called jiyutan by comparing different computational models. based on the comparison of different schemes, the change of the discharge and the flow current in a branch were analyzed, and the relationship between the flow condition and excavation area, scope as well as mode was discussed, the conclusions show : ( 1 ) in a branching rocky rapids, the velocity may be reduced and flow condition can be improved by excavating one channel partly
本文在對各種數學模型比較的基礎上，應用二維水動力數學模型研究典型石質汊流灘? ?廣西潯江鯽魚灘航道整治工程方案，通過各方案計算結果比較，分析了不同汊道的開挖及汊道內不同開挖面積、開挖范圍以及開挖方式所引起的分流比及工程區域航道水力條件的變化規律，研究結果表明： （ 1 ）對于石質汊流灘來說，在某一汊道通過局部開挖河槽，擴大過水斷面面積，可以達到降低工程段流速、改善局部水流條件的目的。 -
On the other hand, the velocity may also be increased by excavating another channel, which should be treated cautiously. ( 2 ) the change of flow rate in a typical branching rocky channel is related to excavation area scope and mode. more excavation area scope and width, more increase in flow rate
（ 2 ）石質汊流灘汊道分流比的變化一般與汊道的開挖面積、開挖范圍以及開挖方式等因素有關，即開挖面積越大，則分流比增加越多；開挖范圍越廣，分流比增加越多；相同開挖面積情況下，寬淺開挖比深窄開挖對分流比的影響要大。 -
Because the yili river belongs to plain broad and shallow moving river, the main channel changes greatly and swings to a large range, which leads to river crooked branching river type and s curved, many fork rivers, the river continent and the river beach in river center, alluvial shoal and beach. the width in some section of the river is up to about 3800m. in flood season it causes serious harm to farmland, factories, residents along two sides
由於伊犁河屬于平原游蕩性寬淺河流，主槽變化不定，擺動幅度極大，河道多呈彎曲分叉河型和s型彎道、多叉河、河心洲，河心灘和沖擊淺灘及邊灘，部分河段河床寬度達3800m ，洪水季節對河道兩岸的田地，工廠，居民等造成極大的危害，素有「三十年河東，三十年河西」之稱。 -
Numerical research on the fiber suspensions in a turbulent t - shaped branching channel flow
形分叉槽道纖維懸浮湍流場的數值模擬 -
Even though hms can be prepared much more easily than mcm - 41 and has certain advantages such as thicker framework walls, superior thermals stability, and a smaller crystalline size. hms have more recently been shown to possess wormhole - like or sponge - like framework structure rather than the long - range hexagonal framework structures characteristics of electrostatically assembled mcm - 41. the wormhole channel motif is a potentially important structure feature for favorable catalytic reactivity, in part, because channel branching within the framework can facilitate access to reactive sites on the framework walls. furthermore the wormhole channel motif suggest that they could serves as ideal hosts for rational nanomanufacturing
1995年， tanev和pinnavaia報道，用中性模板劑合成了一類新的六方介孔固體（ hms ） ，它具有不同於用靜電路徑合成的mcm - 41介孔固體的物理和化學性能，如制備工藝簡單、孔壁厚、熱穩定性好和晶粒尺寸小等。 hms還具有蜂巢或海綿狀結構特徵，而不象mcm - 41那樣是長程有序的六方結構。這種蜂巢或海綿狀結構特徵除有利於催化反應，反應物易於接近孔壁上的反應位外。 -
A new design of fractal branching channel net for cooling of electronic chips is studied. based on the generation of a fractal branching net, heat transfer and the required pumping power for fluid flow in fractal microchannels and the parallel channels are compared
論文最後介紹了一種分形微管道網路，在給出其構造過程的基礎上，利用有限元法將其傳熱能力、所需泵送功率與平行微管道網路進行了比較。
