随着电信传统网络向NFV虚拟化网络的转型和全面演进,虚拟化网络性能分析和优化成为网络运维的重大任务和挑战之一。鉴于ping、iperf等传统的IP网络性能检测工具以及华为公司的IP染色技术存在的缺点和问题,本文提出一种基于软探针的NFV虚拟网络时延计算方法,通过构建两个虚拟机之间完整的端到端的IP路径,选择在4个关键节点放置软探针获取和汇总目标业务流量,通过哈希算法识别、统计流经4个关键节点的IP报文,根据各节点的计数及时间戳在沿途各节点的变化情况,计算出网络时延。

Objective:To investigate the value of spleen and pancreatic tail thorax translocation on the residual stomach esophagus ***:10 patients with esophageal carcinoma after gastrectomy were enrolled in this study. Lesions were removed through left thoracotomy and residual stomach was fully mobilized,with short gastric artery being re- *** and pancreatic tail were dissected from the back of peritoneum and transposed into *** stomach esophagus anastomosis was ***:All the operation went *** were recovered rapidly and a relatively good prognosis was *** leakage and pleural effusion happened in one case respectively,but these com- plications were cured through conservative management without operation ***:Residual stomach is an ideal candidate for the replacement of esophagus and residual stomach esophagus anastomosis is a simple operative alternative with few trauma and good results for the treatment of esophageal carcinoma after gastrectomy.

Journal of Applied Mathematics and Physics 2024年第8期12卷 2920-2927页

作者： weijie Lin Minhong Yang Chenhao Sun Kaiwen guan Xiaoliang Zhou School of Mathematics and Statistics Lingnan Normal University Zhanjiang China

In this paper, the dynamic properties of a discrete predator-prey model are discussed. The properties of non-hyperbolic fixed points and hyperbolic fixed points of the model are analyzed. First, by using the classic Shengjin formula, we find the existence conditions for fixed points of the model. Then, by using the qualitative theory of ordinary differential equations and matrix theory we indicate which points are hyperbolic and which are non-hyperbolic and the associated conditions.

Engineering（科研） 2024年第1期16卷 38-45页

作者： Zhaoli Wang Changbin guan Xudong Wang weijie Zheng Longfei Su Advanced Space Propulsion Lab Beijing Institute of Control Engineering Beijing China

In order to improve the reliability of the spacecraft micro cold gas propulsion system and realize the precise control of the spacecraft attitude and orbit, a micro-thrust, high-precision cold gas thruster is carried out, at the same time due to the design requirements of the spacecraft, this micro-thrust should be continuous working more than 60 minutes, the traditional solenoid valve used for the thrusts can’t complete the mission, so a long-life micro latching valve is developed as the control valve for this micro thruster, because the micro latching valve can keep its position when it cuts off the outage. Firstly, the authors introduced the design scheme and idea of the thruster. Secondly, the performance of the latching valve and the flow characteristics of the nozzle were simulated. Finally, from the experimental results and compared with the numerical study, it shows that the long-life micro cold gas thruster developed in this paper meets the mission requirements.

隐蔽性证据的细节性、独特性和实质隐蔽性与证据的证明力密切相关。在刑事案件中的证明功能层面,隐蔽性证据作为口供补强的延伸和拓展,在定罪量刑方面发挥着关键作用,可以防止口供翻供。然而在运用层面,易引发侦查人员认知、制度设计、证据核实等方面的风险。对此,侦查人员应巧用大数据技术收集证据,转变理念避免污染证据,完善程序运行机制实现过程控制以降低隐蔽性证据运用的风险。
