研究的主要結果具體如下： 1 、研究了硫酸浸出鋅浮渣並分析了影響浸出率的各種因素，確定了浸出鋅浮渣的最佳條件為：液固比為6 ： 1 ，攪拌速度為250r min ，粒度為- 120目，酸浸時間為5 . 0h ，硫酸濃度30 ，鋅浮渣的浸出率大於92 . 0 ； 2 、在綜合和比較了目前除錳和除鐵的各種方法基礎上，提出了過硫酸銨氧化除錳方法和選擇了針鐵礦-氧化水解聯合法除鐵方法，並分析和討論了影響除錳率和除鐵率等各種因素，確定了除錳的條件為：溫度90 ， ph值5 . 4 ，反應時間3h ，過硫酸銨達到理論值的1 . 2倍，除錳率超過99 . 86 ；聯合法除鐵的條件為：氧化反應時間1 . 5小時、溫度控制在90 92 、 ph值5 . 2 5E ) lack of foresight on finance lease scheme, which causes irrational tenor structure and imbalanced annual outflow of rental payments, results in funding costly. to solve aforesaid problems, thesis finds out the following principles for optimizing ca ' s aircraft finance : a ) determining the volume and currencies of ca ' s cross - border aircraft finance based on the annual outflow of foreign debt repayments and annual net inflow of foreign exchange, so are the dominated currencies in debt. b ) enlarging the portion of borrowings at floating interest rate in ca ' s whole foreign debt
針對以上存在主要問題，本文進一步提出了優化飛機融資的總體構想，包括：根據其每年的外匯流入總量及幣種構成確定國航合理的飛機境外融資規模應與負債幣種；在利率結構方面，擴大浮動利率在整個國航外債中的比重，選擇適當時機將部分固定利率貸款轉換為浮動利率貸款；在飛機引進多元化方面，通過與飛機製造廠商、出租公司飛機互換的方式優化機隊構成，結合提前中止現有飛機租賃就能夠起到優化債務結構和機隊構成的事半功倍的效果，以及在未來飛機融資中優先使用經營性租賃等。The author discusses the causes of international monetary crisis. then the author reviews the mundell ’ s theory of oca and its recent development, analyzing the counter - effect of international monetary cooperation. based on these theoretical works, the author summarizes the typical viewpoint about which is the better exchange - rate regime between the fixed exchange rates and the floating exchange - rate, analyzing the recent development of the choice of exchange rate regime, such as the theory of original sin and two poles approach
第一章從國際貨幣合作和國際經濟政策協調等概念的界定入手，探討了國際貨幣體系悖論的制度背景和國際貨幣危機產生的原因，進而闡述了蒙代爾「最優貨幣區理論」及其最新發展，分析了國際貨幣合作中的逆效等問題，並在此基礎上，總結了傳統的固定匯率制度與浮動匯率制度孰優孰劣的觀點及當前國際匯率制度選擇理論的最新成果，例如原罪論、恐懼浮動論和兩極論等。Pda laser flow velocity testing technique was used to measure the flow velocity of solid particles in the solid - liquid - gas three - phase system in a flotation cell and obtained the velocity distribution of solid particles so as to provide reliable data for the study on adsorption and deadsoption mechanism of particles onto and off from bubbles
採用pda激光流速測試技術，在固-液-氣三相體系中對浮選槽中固體顆粒進行了流速測定，獲得了固體顆粒的速度分佈，為礦粒與氣泡粘附過程和脫附過程機理的研究提供可靠數據。分享友人
