But repetitious launching tests show that there is a remarkable error in the measurement of the angle which is measured in the technical position . the error has so notable effect on sight precision of weapons that this scheme is abandoned in the design of later missile weapons 但经多次发射试验证明,技术阵地测量的两基面夹角存在较大误差,对武器的瞄准精度产生了较大影响,以致后继的某些型号放弃了基面转换方案。
At last , our experimentation uses java rmi but not pvm used by much many parallel and distributed experimentations . we combine distributed theories with realization technology that would be basis of the industrialization in future 最后，不同于一般的并行分布式实验以pvm进行实验，本文中对信息中心调度策略实现模型是依托先进的javarmi技术，将分布式理论和分布式实现技术有机的结合了起来，为后继的分布式理论产业化研究打下了基础。
The i for according to front or p proceeds estimate , because of but compress ratio to want higher than i , the data measure the average to attain the i of 1 3 or so . p p for b for is rightly in front and back with subsequencep a basis of front for iswhich have error marginning , if p is also p , can result in the error margin to spread P帧根据前面的i帧或p帧进行预测，因而压缩比要比i帧高，数据量平均达到i帧的1 3左右。 p帧是对前后的b帧和后继的p帧进行解码的基准帧。 p帧本身是有误差的，如果p帧的前一个基准帧也是p帧，就会造成误差传播。
The so - called automatic recognition of modulation ( amr ) schemes automatically classifies the modulation types from the samples of received signal by abstracting the related features such as amplitude , frequency , and phase , followed by employing proper recognition algorithms based on the fast digital signal processing techniques and advanced computing technology . the result of amr can be used in the following processing blocks such as demodulation , supervision processing and anti - interference processing and so on 所谓调制类型自动识别( amr )是根据接收信号样本提取出振幅、频率和相位的特征参数，然后借助信号处理技术和计算机快速处理能力，采用合理算法进行处理，从而实现对未知已调波调制类型的自动识别，为后继的解调、监控、抗干扰等处理奠定基础。
The paper discusses following issues in the introduction of the modules : dos defense support in the pppoe protocol ; bring forwards and implement a pppoe connection controlling method based on ppp ; windows tapi - oids sequence which the virtual dialup adapter has to deal with properly ; how to deal with the communication between kernel driver and the application the paper makes an all - sided study on the pppoe protocol for the first time in china , so it has relatively important values of reference for following study and developing ; it not only realizes a practical tool for adsl , which has tremendous economy profits , but also perfects the pppoe c / s platform , which could support corresponding r & d actives at source code level 在对这些功能模块的介绍过程中还做了以下工作：探讨了pppoe协议在防范dos攻击方面的支持；提出并实现了一种基于ppp协议的pppoe连接控制方法；记载了虚拟拨号网卡完成安装和开始工作所要正确处理的windows系统的tapi序列；使windows应用程序与核心驱动程序之间正确通讯。本课题在国内较早对pppoe协议进行了较为全面的研究，故对后继的开发和研究都有着较为重要的参考价值；该课题不仅实现了一个实用的adsl工具，带来了可观的经济效益，更完善了在pc上实现的pppoe ‘服务器/客户端’结构平台，从而为相关研发提供源代码级的支持。
In the wavelet image compression system ， the choice of wavelet basis directly determines the statistical characteristics of wavelet coefficients , thus it not only affects subsequent processes , but also affects the final compression ratio and the the quality of reconstructed image . the method of realizing wavelet transform determines computational complexity , whether the transformed data can be lossless recovered or not , etc . , accordingly it can affect the time spending on compression and the quality of reconstructed image 在小波变换图像压缩方法中，小波基选择的好坏，直接决定小波系数的性质，从而影响压缩过程中后继的其它处理，影响最终的压缩比和图像重建质量；小波变换的实现方法决定着计算的复杂度、数据的恢复性能等，从而影响压缩时间和图像重建质量。
Under varied loads such as cyclic and / or transient loading , soil structures or foundation will induce permanent and / or fluctuating plastic deformations . such plastic deformations are cumulative and / or alternating in nature with increase of time of loading during a sequence of cyclic loading . if the resulting accumulated deformations is limited within a given bound or the alternating deformations will be adapted to a given plastic state after a certain cycle numbers or a certain period of loading , the soils will be in shakedown state 在复杂变值荷载作用下，结构有可能出现两种状态：一种是在若干次载荷循环之后，塑性变形趋于稳定，在此后继的载荷循环中结构表现为纯弹性响应，这种状态称为安定状态( shakedown ) ；另一种则是塑性流动一直持续地发展或不断反复，直至结构破坏，结构的破坏有两种型式：一种是由塑性应变的累积引起的增量塑性破坏；一种是塑性变形多次反复引起的疲劳破坏，也称为交变塑性破坏。
A study of combustion of the furnace in high - speed - wire factory of tangshan steel company is made , from which the conclusion is acquired , that is the process is a casual process of nonlinear and distributed parameter with big inertia , pure lag and casual disturbance . this makes prepare for further studies 研究了唐山钢铁公司高线厂的蓄热式加热炉的燃烧情况，得出了结论，即其过程为大惯性、纯滞后、受随机干扰的非线性分布参量过程，为后继的研究作了准备。
