本文主要通過實驗對搖擺條件對單管強迫循環中汽液兩相流動不穩定性的影響，同時在d分區法的前提下，在兩相區基於漂移流模型，一定的守恆條件下，在搖擺和不搖擺工況中用線性小擾動法對實驗段的壓降對入口流速的擾動的響應進行了分析。Then, four different computation methods are applied to compute the hydrodynamic performance of the rotor, which are single - disk single - tube method ( sdst ), double - disk single - tube method ( ddst ), multi - tube method ( mtt ) that are based on momentum theorem and vortex method ( vtth ) that is based on potential eddy theory
然後，採用基於動量定理的單盤面?單流管方法（ sdst ） 、雙盤面?單流管（ ddst ）方法、多流管（ mtt ）方法以及基於勢渦理論的渦方法（ vtth ）計算直葉擺線式水輪機的水動力性能。Flow details of measurement indicate that the coupling of periodic separated flow ( such as low frequency swinging of separation line ) with nozzle flow may cause aft - end internal flow unsteady. recirculation flow gains more energy from the main flow, at the same time the turbulence intensity increases
通過對測量結果的分析，我們認為分離流動的周期性（如分離線的低頻擺動）與噴管流動相耦合，會造成燃燒室尾部流動的非穩態效應增強，增加了迴流區從主流中獲得的能量，也加劇了流場的湍流脈動。Track maintenance technology is raising while high speed railway was developed in abroad. the developed countries like japan, french and german etc. had made their own high speed track management code. strict managing track smooth qualities by using advanced track measuring car, exhibiting their maintenance level by using advanced measuring system, mechanism construction, scientific diagnosis and automatic management technology
國外高速鐵路迅猛發展，線路維修養護技術水平也不斷提高，主要表現在採用先進的檢測系統、高度機械化作業方式、科學診斷和自動化管理方面。我國鐵路近十年取得了很大的發展，經歷了四次大提速， 1998年8月開始，我國引進瑞典x2000擺式列車在廣深線試運行（ 200km h ） 。A set of 25 numbers of eye - catching and beautifully designed customs drug detector dogs publicity cards are provided for collection at customs control points. each card displays customs hotline and motto calling for public assistance to fight drugs
一套25張緝毒犬宣傳咭已擺放在各管制站免費供市民索取，每張緝毒犬宣傳咭都展示出海關舉報熱線電話號碼和宣傳語句呼籲市民幫助打擊毒品活動。At the same time a method of utilizing round swing transition horn is put forward to void shock produced in the process of welding two round pipelines of the same or similar diameter by such experiments and debugging
同時通過附加圓擺動的折線軌跡曲線的實驗和調試，確定了利用圓擺動過渡尖角的方法，避免了當焊接兩圓管直徑相同或是相近時在焊接過程中產生的沖擊。As a monumental project of the large - scale development in the west, it covers nine provinces and municipalities along its gas pipelines. consequently, chang zhou factory of coke and chemicals is confronted by the challenges of changing market, government subsidy reduction and natural gas introduction. how to extricate from the predicament and maintain sustained growth is a primary problem, which the coke industry and particularly the coke factories affected by the project, should ponder over
西氣東輸作為西部大開發的標志性工程；在橫跨東西部九省一市的漫長管線上已全面啟動，與之相關的常州焦化廠正面臨市場變化帶來的沖擊、政府補貼的削減與天然氣導入的威脅；如何在新的形勢下，擺脫困境獲得企業的長效發展，是焦化行業尤其是受西氣東輸沖擊的各焦化廠正在思考和摸索的首要問題。分享友人
