For an arbitrarily distributed retrial time distribution , the necessary and sufficient condition for the system stability is obtained , assuming that only the customer at the head of the orbit has priority access to the server 在假定重试区域中只有队首的顾客允许重试的情况下,重试时间具有一般分布时,得到了系统稳态的充分必要条件。
Thereby we conclude the behavior activity rhythm . this thesis introduces the ingestive behavior , defence and attach behavior , reproductive behavior and the daily time distribution during the reproductive period 文中报道了鳄蜥的摄食行为( ingestivebehaviour ) 、防御与攻击行为、繁殖行为( reproductivebehaviour )以及鳄蜥在繁殖期日活动的行为时间分配。
This paper proposes principle and method of optimizing energy and time distribution in elevation to obtain good performance in the frame time , and this method has been used in engineering project of several phased array radars 文中提出了仰角扫描能量时间的优化分配原则和方法,使雷达的能量和时间在帧时间内分配达到性能最佳,这种方法已在多部相控阵雷达设计中采用。
The time distribution feature of rainfall trend for global land seasonal and monthly rainfall indicates that the rainfall in global land areas is characterized by the negative trend variation . the interannual and interdecadal fluctuations of the rainfall are clear 指出在1948 - 2001年,全球3 - 5月的降水量以负趋势为主要的变化特征,降水有明显的年际和年代际振荡。
The ecology part is mainly discuss the activity rhythm , behavior and the time distribution on activity . shinisaurus crocodilurus ' s hibernation , the choice of habitat etc . the current danger condition and protection part report the current sort distribution and the number 生态部分,主要探讨了鳄蜥的活动节律、行为以及行为的时间分配、鳄蜥的冬眠、鳄蜥对生境的选择等内容。
The proper structure of reading sequence and the structure of time distribution of reading in chinese reading progress , are two important means to analyze the student ' s learning activities , with my analysis through the reading , the chinese reading , and constructivism 通过阅读学、语文阅读学、建构主义理论的分析,语文阅读循序渐进规律、语文阅读的时间观成为分析学生语文阅读学习活动的两个重要依据。
The formation of super - large deposits have specical geological backgroud and enviroment . its element association , mineral association , space - time distribution , metallogenic factors , formation functions and metallogenic medols show diversity , complexity and particularity 超大型矿床的形成是一定地质背景与环境的产物,其元素组合、矿物组合、时空分布、控制因素、形成机制、成矿模式等具有多样性、复杂性、特殊性。
Based on the model of linear quadratic relationship of dose - response , dosimetric method for assessment of deterministic hazard of low let radiation accident exposure in accordance with different time distribution of dose were developed in the paper by means of given thresholds of deterministic effects 辐射事故照射,除大剂量急性照射情况外,更多的还有受照延续时间不等、照射水平不一的多次受照情况,甚至尚有数天内连续受照的。
The teachers can gather the feedback from the sequence and time distribution in the students " chinese reading progress , judge the learning condition , and guide the students in time . of course , these means are guides to tackle relevant information too 教师可以通过“阅读顺序结构”及“阅读时间分配分配结构”来获取反馈信息,再依据具体的教学内容、教学目标、学习者特性等不同条件,进而初步判断学生学习状况,以便及时给予指导。
This article tries to analyze the time distribution , subjects distribution , authors distribution and journals distribution of papers on library spirit from 1988 to 2005 by using statistical method in order to discuss the research actuality and the future 本文采用文献计量方法对1988 - 2005年我国“图书馆精神”研究领域的论文进行时间分布分析、主题分布分析、著者分布分析和期刊分布分析,从而探讨“图书馆精神”研究发展状况与未来发展趋势。
