消防救援队伍战勤保障预案是针对特定情况可能发生的火灾及其他灾害事故,对灭火救援有关保障问题预先安排的作战文书,是实施灭火救援行动的重要依据。编制一个科学合理、内容翔实、贴近灾害现场实际的战勤保障预案,有利于指挥员在灾害现场临阵不乱,快速进行力量部署,准确科学进行灭火救援指挥,将灾害损失降低到最低限度。高原高寒地区因其海拔高、气候寒冷等因素,给消防战勤保障工作带来一定的困扰。因此,加强高原高寒地区战勤保障预案编制意义重大影响深远。改革转制以来,消防救援队伍战勤保障工作坚持“平时战时相结合、自保联保相统筹、物保技保相配套、保障管理相协调”的原则,逐步建立完善了消防救援队伍战勤保障体系。战勤保障预案制定是强化前置保障的重要前提,也是提升队伍战勤保障能力的重要方式方法。因此,本文从预案制定的意义和原则着手,对高原高寒地区的战勤保障预案制定进行研究。

Approach for analyzing the ultimate strength of concrete filled steel tubular arch bridges with stiffening girder

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第5期8卷 682-692页

作者： zhang zhi-cheng XIE Xu zhang He CHEN Heng-zhi Department of Civil Engineering Zhejiang University Hangzhou 310027 China

A convenient approach is proposed for analyzing the ultimate load carrying capacity of concrete filled steel tubular (CFST) arch bridge with stiffening girders. A fiber model beam element is specially used to simulate the stiffening girder and CFST arch rib. The geometric nonlinearity, material nonlinearity, influence of the construction process and the contribution of prestressing reinforcement are all taken into consideration. The accuracy of this method is validated by comparing its results with experimental results. Finally, the ultimate strength of an abnormal CFST arch bridge with stiffening girders is investigated and the effect of construction method is discussed. It is concluded that the construction process has little effect on the ultimate strength of the bridge.

On overload control of parlay application server in next generation network

引用

The Journal of China Universities of Posts and Telecommunications 2008年第1期15卷 43-47,60页

作者： zhang Qi-zhi School of Computer South China Normal University Guangzhou 510631 China

After analyzing the features of the Parlay application server（AS）, which provides many services with different time constraints in the next generation network（NGN）, a selfadapted overload control algorithm implemented in Parlay AS is proposed. In this algorithm, the service process module in parlay AS uses the earliest deadline first （EDF） serving rule to serve messages, and the overload control mechanism, using the Leaky Bucket algorithm to control message flows, is triggered by estimating the queue waiting time of a newly arriving message. By simulation it shows that this algorithm is a simple, easy-to-use, and available algorithm.

On the M/G/1 queueing system with multiclass customers and fixed feedback

引用

The Journal of China Universities of Posts and Telecommunications 2008年第2期15卷 114-121页

作者： zhang Qi-zhi School of Computer South China Normal University Guangzhou 510631China

The M/G/1 queueing system with multiclass customer arrivals, fixed feedback, and first come first served policy is considered, where different classes of customers have different arrival rates, service-time distributions, and feedback numbers. The joint probabifity generation function of queue size of each class and the Laplace-Stieltjes transform of the total sojourn time of a customer in each class are presented, which extended the results obtained by Choi B D. The mean queue size of each class and mean total sojourn time of a customer in each class are obtained with this result. The results can be used in computer and communication networks for their performance analysis.
