This thesis adopts empirical research methods, with changjiang communication navigation bureau as a study object, under the guidance of the public financial theory and with zero - base budget idea and activity - based costing system applied ; it provides the general thought by which we investigate each itemized outlay ration standards using the method of sourcing " the chain of the reason of necessary cost " and provides the idea of distributing the common cost in the light of the actual time of the non - commonweal and commonweal communication, researching the method of investigating the budget ration standards of over - water commonweal communication institutions. the research harvest has important theoretical and practical sense to the over - water commonweal communication institutions when making budget
本文採用實證研究的方法，以長江通信導航局為研究對象，在公共財政理論的指導下，運用零基預算和作業成本法的基本思想，研究了水上公益通信單位預算定額標準的測定方法，通過追溯「必要費用成因鏈」來測定各項費用定額標準和根據非公益性通信與公益性通信實際發生時間來分攤共同費用的思想，研究的成果對水上公益通信單位編制預算具有重要的理論和實踐意義。 -
There still have not mature standard, every research institution have his own point of view and develop the product for their own business needs, all of those system have much limitation, for example, they base on the technology of windows, the common use and expansibility is very limited etc. in our country, the research still begin now, most of the existing modeling system base on the structure modeling and can not sustain the new modeling standard such as uml etc. the author disscuss the object - oriented modeling support environment in this dissertation with the he lp of research result in recently years and the technology at present and in future, some modeling standard and views have been bringed forward, at the same time this dissertation has also introduced the umlware system which is the product of the reseach, including the technology of development for the umlware system and it " s strategies of modeling
面向對象建模支持環境研究及其工具的研製成為當今國際領域的研究熱點，何為優秀的面向對象建模支持環境，目前國際上並沒有統一的標準，各個研究機構對其亦持有不同的觀點，並根據自己的商業需要開發出符合自己特點的建模產品，這些系統仍存在著眾多的弊端，比如幾乎都是基於windows技術，通用性差，擴展性方面受到限制等。國內在這方面的研究仍處于起步階段，已有的建模系統大都基於結構化建模技術或者無法支持最新的面向對象建模技術如uml標準。本文根據作者近幾年的研究結果，結合目前和未來的技術從理論上探討了面向對象建模支持環境，提出了一些建模標準和觀點，並詳細介紹了基於這種研究成果下自行開發的面向對象建模支持系統umlware ，論述涉及該系統的研製技術、開發思路和建模策略。 -
This article plans to base on the comparison of the film 《 phantom lover 》 and 《 the phantom of the opera 》 separately directed by maxuweibang from hongkong and joe schumacher from america, and the article puts emphasis on the artistic feature time significance as well as the thought of the chinese version, hope to explore certain common characteristics in the exchanges of chinese and foreign literature and culture form this standpoint
摘要本文擬立足於由香港馬徐維邦執導的電影《夜半歌聲》與美國舒馬赫執導的《歌劇院幽靈》的比較，重點解讀中國版的《夜半歌聲》的藝術特色、時代意義以及思想內涵等，並希望以此為切入點，探索中外文學與文化交流中的某些共同特徵。 -
This text completely and systematically studies the status and the development of the pyrolysis and the fluidization of biomass, which distill the bio - oil in the domestic and international area, as well as the existing problems. this thesis primarily include following aspects : ( l ), by experimenting and measuring the energy ( heat value ) and the content of c, h, n chemical element of right 20 kinds of common biomass, on the base of the experimental result, and respectively established the biomass energy predict experiment formula with the element of h and c is from change, and passed the ro. os examination, which provides the basis and convenience for flash pyrolysis fluidization device energy to convert the rate to compute with biomass energy utilization calculation ; ( 2 ), proceeded the tg and dtg experimentation equal velocity ( 10 ? / min, 20 ? / min, 40 ? / min, 60 ? / min ) heating and constant temperature heating by studying on eight kinds of biomass samples, according to the experimental data and arrhenius formula, we established the dynamics model of pyrolysis of, then, using the goast - redfern and p function, we also solved the dynamics parameters and analyze out every kind of biomass ' s frequency factor and parameters of activation energy, and established the every kind of dynamics model of pyrolysis of biomass, all of these provide the theories and basis to make sure the reactor ' s flash pyrolysis work temperature scope design and the describing of pyrolysis reactor dynamics ; ( 3 ), in order to study and ascertain the process of heat completely getting to pyrolysis time of varied size biomass particles, we observed and measured the ratio of length and diameter ( l / d ) with the varied biomass through electron microscope, we concluded the l / d ratios usually is from 5. 0 to 6. 0, the average is 5. 3 ; ( 4 ), we studied the process of biomass transiting and the theory of complete pyrolysis time with the theory of complicated heat field, we got the time ( t ) of the varied size biomass particles arriving to complete pyrolysis, and we knew that the complete pyrolysis time and the time which get to the biggest production ratio are identical, all of these studies provide the theory base for design and forecasting the flash pyrolysis reactor solid state resort time ; ( 5 ), according to the above experiment result, synthesize to make use of the engineering the mechanics, engineering the material, machine the design to learn the principle, deduce, establish the theory of rotation cone flash pyrolysis reactor material resort time ( t ) and reasonable rotation velocity ( or frequency ) relation theory ; and ( 6 ), we gave the reactor ' s smallest cone angle certain, reactor cone wall strength design theory, the reactor production ability theory, the power design method and the critical rotation velocity theory
