The paper applyed principle analysis and numerical computation to compare the scheme of particle injection syphon and convergence - turn tube. the last method was adopted to conduct research because it could produce high concentrated particles stream and operated conveniently. 2
本文應用原理分析、數值計算等手段，對粒子加入、彎管和收斂?折管方案進行了比較，認為收斂?折管方案可以產生發動機在飛行過載中的凝相粒子聚集效應，且燒蝕參數控制方便。 -
And then according to the result of simulation, make into kind tube proceed the real object experiments, the conclusions of experiments is again excellent to turn to simulation according to the real object true of result, promote to simulation really perfect. this project, we divided 2 steps
即用magic軟體來計算所要設計的磁控管的腔體，然後根據模擬的結果，做成樣管進行實物實驗，根據實物實驗的結論又優化模擬的結果，促進模擬的完善。 -
It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition, etc. next, it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature, making it up the dew point ; use the abrasion - resistance material to resist abrasion
討論了飛灰磨損性能、管壁受飛灰沖蝕的近似計算、灰粒對順列管和錯列管的磨損計算、煙氣走廊引起對流管束的磨損機理、空氣動力參數對飛灰沖蝕的影響以及受熱面壁溫變化及煙氣成份對飛灰磨損的影響等問題。接著提出了解決的措施：降低平均煙氣流速；降低飛灰濃度；使用鰭片管、螺旋翅片管代替光管；選擇合適的結構及排列方式，減少煙氣中so3的含量；提高受熱面壁溫使之大於煙氣的露點溫度；採用抗腐蝕材料作受熱面等防腐蝕的措施。 -
Turn the coupling with hand or tube spanner and check that there is no clash of foreign matters and jamming in the pump body. if any, remove them before starting
用手或管子鉗轉動聯軸器，注意泵體內有無異物碰撞雜聲和卡死現象，如有應清除後方可開車。 -
Imitating the shape of a piano, this sculpture is composed of two main parts the bamboo tubes and a stainless steel sheet. varying in length, the bamboo tubes collect various amount of rainwater and turn at the pivot at different time intervals. when the water comes out of the tube, it rotates back to its original position and hits the stainless steel sheet with a pounding sound
它外形彷似一臺鋼琴，由一組竹筒及一片不銹鋼片組成，每根竹筒長度不一，儲水量不同，因此會于不同時間依中軸轉動，當水被排出后，竹筒立即反彈至原本位置，敲擊鋼片，發出清脆而莊嚴的聲響。
