水管接頭-
E was reclining upon soft downy cushions, covered with blue satin spotted with silver ; her head, supported by one of her exquisitely moulded arms, rested on the divan immediately behind her, while the other was employed in adjusting to her lips the coral tube of a rich narghile, through whose flexible pipe she drew the smoke fragrant by its passage through perfumed water. her attitude, though perfectly natural for an eastern woman would, in a european, have been deemed too full of coquettish straining after effect
那是一間類似婦女休息室的房間，圓形的，天花板由玫瑰色的玻璃嵌成，燈光由天花板上下來，她這時正斜靠在帶銀點兒的藍綢椅墊上，頭枕著身後的椅背，一隻手托著頭，另外那隻優美的手臂則扶著一支含在嘴裏的長煙筒，這支長煙筒極其名貴，煙管是珊瑚做的，從這支富於彈性的煙管里，升起了一片充滿最美妙的花香的煙霧。 -

To provide necessary data for design bypass pipe, an enlargement to bi liu river reservoir, the following problems have been studied by hydraulic model and theoretical analysis : the energy losses in water head of the bypass pipe system and of the flow - control valve and their scale effects, measurement and calculation of the discharge of the bypass pipe system during the bypass pipe system operation with and without the new water power station, the hydraulic characteristics of the water tunnel and draw - off pipe, the flow rate of the aqueduct bridge and the draw - off pipe and the water elevation of the flow in the aqueduct bridge during the old water power station operation with and without the new water power station
大連市碧流河水庫供水工程取水頭部由引水渡槽、節制閘、進水閘、泄水閘等建築物組成。由於本工程場地條件限制，增設旁通管后布置非常緊湊，管道急轉角度大且轉彎距離較小，對于管內水流流態是否滿足要求，需要經過模型試驗進行論證，以確保工程的可靠性。旁通管具有上水與泄水要求，對其過流能力也要經試驗確定，為碧流河水庫增建旁通管設計提供依據。 -
It is more accurate than traditional method at the aspect of calculating head loss, pipe flow and node pressure of hydrant. this mathematic model can also be used in the inside and outside of water supply piping calculation and it is excel hardy cross - piping calculation
該方法在計算水頭損失、管段流量、消火栓節點壓力等方面比傳統方法要更加準確，也可被借鑒到室內或室外的給水管網計算，並優于常見的哈代-克羅斯管網平差方法。 -
In this article, through lab and engineering site trials that the physical data of new type pipe materials is corrected, the results are as follow : ( l ) the expansion coefficient of new plastic pipe materials is more large than that of iron pipe. ( 2 ) new plastic pipe materials have different heat - resisting character and according to the water temperature to choose pipe materials ; ( 3 ) the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ; ( 4 ) probing into the press - resistance character of new plastic pipe materials
本文通過試驗室試驗及工程現場試驗，對新型給排水管材的幾個重要的物理性能參數進行實驗測定，糾正了以往的錯誤認識。研究結果表明： （ 1 ）新型塑料管材線脹系數遠遠大於鋼管和鑄鐵管，設計和施工中要嚴格考慮管道的伸縮； （ 2 ）新型塑料管材耐高溫性能各不相同，需根據管內水溫選定管材； （ 3 ）新型管材水頭損失遠小於鋼管，並對原水頭損失計算公式進行了修正； （ 4 ）對于塑料管材的耐壓性能進行了探討。 -
The mathematical analysis shows that, with disregarding local head losses and by means of different simplified rigid models, the calculated results of the maximum pressure in a pressurized pipe system containing trapped air mass are equal to and independent of the initial length of the water - column
摘要通過數學分析證明，在不計局部水頭損失時，目前常用的幾種簡化剛性數學模型的最大氣壓計算結果相等，並與管道內初始充水段長度無關。
