The data collection mission is important in distributed simulation systems . the data collection and fom agility problems are solved in the framework . based on the dynamic object model representation , an adaptive data logging policy is proposed in yh - fwf , which can meet the new requirements of hla distributed simulation system data collection mission 数据采集是分布仿真系统中的重要任务， hla分布仿真系统的数据采集任务具有一些新的特点，本文提出以对象模型动态表示为基础，在yh - fwf框架中以可接入的方式提供数据记录能力，很好地解决了hla仿真过程中的动态数据采集问题。
In this article , the following is discussed : the realization of signal processing and data logging circuit , the design of optic - fiber sensors and under - well single transfer circuit . a laboratorial model is built to simulate multiphase - flow meter ' s working condition . finally , feasibility of the technical is proven by some examinations 论文中主要讨论了以dsp芯片为核心的多相流量计信号处理及数据记录电路的设计、几种应用于该种多相流量计的光纤传感器的设计、传感器信号变送传输电路设计、以及多相流组分与光折射率关系的推算，并设计油井管道模型模拟多相流体的流动，在此基础上通过试验初步分析和验证了这种计量技术的可行性。
Much work has been done in this paper : ( 1 ) have analyze the principle of fiber optic gyro ( fog ) and strap - down inertial system , and investigate the typical arithmetic of the attitude matrix . ( 2 ) have settled a set of platform to do experiment , have programmed the data logging and processing software , have done experiment to analyze the properties of applying the fog inertial system in the measurement 本文从该方法的原理、实验设计和分析探讨等方面详细阐述了用捷联式光纤陀螺惯性系统测量三维物体形变的新方法，提出了适用于工程测量的解算姿态矩阵方法，总结了减小测量误差的几个方面，根据工程实际对测量系统要求提出了改进意见，对实际的工程测量应用起到了积极的作用。
6 . make some amendments to the daily logfile system : write the daily logging data to the memory using cache technology , mitigating the problem of dom insufficient space ; avoid logfile overflow by using daily log queue technology ; cope with repulsion problem of data logging and data sending 6 .对日志系统做了如下改进:使用cache技术，把日志数据、写在内存中，缓解了dom空间不足的问题;使用日志队列技术避免日志溢出;实现了日志和日志发送程序互斥的访问日志数据。
