In this thesis, the multi - channel sharing system is considered as a stochastic service system. based on the steady state solution of the birth and death process which state space is a limited set, utilized m / m / n / n / m queue model, the call congestion ratio formula and the channel utilization ratio formula fitting to the limited user system are derived. drawing support from the visual data analyzing function of the software matlab, the value divergence between the formulas and the corresponding one fitting to the infinite user system are compared
本文將多通道共用通信系統視為一個隨機服務系統，根據有限狀態生滅過程的穩態解，利用m m n n和m m n n m兩類排隊模型，分別推導出了無限用戶和有限用戶兩類多通道共用系統的呼損率公式和通道利用率公式；藉助于matlab的可視化數據分析功能，比較了這兩組公式在數值上的差異；指明了兩組公式的適用條件。 -
The results of population censusesby - censuses form the corner stone of the system. these benchmark data are taken together with statistical data generated from administrative systems ( such as birth, death and passenger movement records ) and sample surveys ( in particular the continuous general household survey ) to form a population statistical database which serves a multitude of purposes, including amongst which the compilation of population estimates
這些基準資料，加上透過其他行政系統（例如出生、死亡及出入境記錄）及抽樣統計調查（特別是持續性的綜合住戶統計調查）所得資料，編制而成的統計數據，連結成一個人口統計數據資料庫，數據可用於編制人口估計及其他眾多用途。 -
The basic systems of rural productivity, such as rural economic systems, organizational systems, infrastructure and the application system of new technology, effectively promoted the development of rural economy ; building grassroots political power in the rural areas and farmers ' participating politics thoroughly changed the old rural political structure ; modern spiritual civilization transformed the old rural culture, and created a new spiritual style ; the building of simple social security system initially protected farmers from birth, old age, sickness and death
農村經濟制度、組織制度、基礎設施、新科技應用體系等鄉村生產力基礎體系的建設，有效促進了農村經濟的發展;農村基層政權的建立及廣大農民的參政議政，徹底改變了舊的農村政治格局，現代精神文明對農村落後文化的改造，造就了新的農村精神風貌;簡易社會保障組織體系的建立，使中國農民的生、老、病、死等有了初步的保障。 -
The characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier have been partially settled by professor yang in [ 1 ], which depends on setting up a method that solving system of liner equations with two boundaries. in this thesis, the author has setted up another method that solving system of liner equations with one boundary on the basis of the former method, and has improved further the characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier
在文獻[ 1 ]中，楊向群教授創立了解含兩個邊界的線性方程組的方法，並利用該方法對對以0為擬飛射壁的生滅過程的特徵數及其概率意義有了部分解決。本文是在此方法的基礎上創立了解含一個邊界的線性方程組的方法，並利用這兩種方法對以0為反射壁和擬飛射壁的生滅過程的特徵數及其概率意義做了進一步的完善。
