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。 -
3 weeks ago … they planned an autograph signing activity on the 8th of feb. . therefore the probability of me coming back is almost zero
三個星期以前…他們計劃了在2月8號有一個簽唱會…所以，我迴文萊的可能性是「 0 」 -
As a result, the algebraic sum of rotatory value of related helix is not equal to zero, thus resulting in optical activity
根據這些螺旋的可極化性，可以準確地預測這類化合物的旋光方向。 -
Several kinds of er fluids with different concentration are prepared and their optical activity are measured with the changes of applied electric field and using a automatic polarimeter. experiments indicate that when none of the external electric field e, concentration c and 9 are equal to zero, er fluids appear optical activity. for a given concentration, optical rotation angle increases with electric field and concentration
實驗發現:無外電場作用時，微乳液沒有旋光效應;當e > o且濃度c和0均不為零時，出現旋光效應且旋光角大小隨電場增加而增加;存在一個飽和電場值es ，當大於es時，旋光角平趨於一定值。 -
In order to study the photochemical activity of the product further, this dissertation, taking methyl orange as a deputy of organism, has studied the relation between the concentration of the organism and the reactive time during the process of light degradation, and, on the basis of the relation, the kinetic process of the photocatalytic degradation was achieved by the treatment on the curve of the organism concentration to the reactive time : zero order reaction of the high organism concentration, first order reaction of the middle organism concentration, second order reaction of the low organism concentration
在產品對有機物的光降解方面，本文主要以產品光降解甲基橙溶液為例，研究了光降解過程中，有機物濃度與時間的關系。並在此基礎上，對有機物濃度與時間的曲線進行了動力學處理，得出產品光降解甲基橙的動力學過程分為三步，摘要即:高濃度時的零級反應、中等濃度時的二級反應和低濃度時的一級反應。
