The second chapter studies the economy of ship ' s power plants, based on the aspects of lowering fuel cost, waste heat recovery, the match of ship, machinery and propeller, increasing propulsion efficiency, increasing the economy of ship ' s power plants, etc. the third chapter discusses in detail the control measures of voyage change cost, analysizes systematically the voyage change cost based on the way of fuel cost, harbor cost, voyage venture cost. the fourth chapter studies the structures and control measures of seafarers cost, maintenance cost, spare parts and stores cost, lubricating oil cost, etc. which are relatively easy to be controlled ; based on the state maintenance decision - making, a mathematical model is put forward, the validity and its solve process are discussed. the control measures of spare parts, fuel cost and lubricating oil cost should be based on scientific budget, through the control means of application, reception, usage, store check, try to acquire the inosculation of theory
第一章主要討論營運船舶運輸成本，對船舶運輸成本的概念、結構、性質與分攤、成本細分進行了分析，從宏觀上闡明了船舶運輸成本的生存環境和生長趨勢；第二章研究了船舶動力裝置的經濟性，在營運船舶降低油耗、廢熱利用、船機槳匹配、提高推進效率、提高船舶動力裝置經濟性的有效途徑等方面進行了闡述和論證；第三章詳細論述並論證了航次變動成本的控制措施，全面系統地分析和總結了航次變動成本，通過對燃油成本、港口使費、航次風險成本的分析與控制，提出了航次風險成本的概念並論述了若干航次風險成本的控制措施；第四章對船舶營運成本中的船員費用控制、維修保養及其費用控制、船舶備件物料管理及其費用控制等幾個主要可控性較高的成本進行了細致的分析並分別討論了相互的控制措施，提出了基於狀態維修決策的馬爾可夫數學模型並論證了模型的正確性及具體解算步驟，對于備件、燃潤物料的控制堅持以科學的預算為前提，以申領、接收、使用、盤存為控制環節，切實做到理論與實踐的密切結合；第五章，結合營運成本的預核算的案例，對船舶營運成本的預算及核算進行了有益的探討，旨在揭示成本發生的動因，並給出了成本預算、核算的編制方法。 -
Keynesianism ' s monetary policy transmission mechanism directly regards interest rate as the core which link money with productive quantity, not by means of price, in a sense, keynesianisrn completely escapes the range to which quantity theory of money confines monetary analysis, representative of monetarism academic category - milton friedman thinks change of quantity of money supply is the most reliable measure standard of monetary propulsion
凱恩斯主義貨幣政策傳導機制直接把利率作為聯結貨幣與產量的樞紐，而不是藉助於物價；從這個意義上說，凱恩斯主義完全擺脫了貨幣數量說，把貨幣分析局限於物價論的框框。貨幣主義學派的代表人物弗里德曼卻認為貨幣供應量的變動是貨幣推力的最可靠測量標準。 -
With the development of morden aero - propulsion system, the simulation technology has became one of the most important means in aeroengine design. aeroengine nonlinear mathematical models, as the basis of engine performance simulation, are not convergence favorably in entire flight scope, because of the solution limitations of nonlinear equation and the engine balance equations
作為數值模擬的基礎與核心，目前廣泛應用的發動機非線性數學模型，由於平衡方程各種迭代解法與模型中非線性方程解法的不足，因而從根本上沒有解決模型在整個包線范圍內的收斂問題，極大地制約了發動機數值模擬技術的發展。
