2 . based on the revelant standards of itu - t and related references , is designed . the general scheme of 32 x 10gbit / s 480km wdm transmission system are designed for the most systems which fiber are model g . 652 基于国际电联的itu - t系列参考标准和信息产业部的相关标准，进行32 10gbit s480km的wdm光纤通信系统总体设计和规划。
" presently available systemic therapies for hepatocellular carcinoma have no documented survival benefit , " he said . " our study establishes sorafenib as the new reference standard for systemic therapy in these patients . 他说： “现在所应用的肝细胞癌全身治疗对于生存率没有任何效果，我们的研究为这类病人建立了以索拉非尼为新参考标准的全身治疗方案。 ”
The senior site quality manager ( io ) or quality unit ( di & a ) is responsible for ensuring specifications , reference standards , sampling plans , test methods , laboratory procedures , and raw data and record management are in place for all laboratory tests and controls 高级质量管理人员或质量部门应保证各种规程、参考标准、样品计划、试验方法，实验室程序及原始数据和记录的管理应与实验室的试验与控制相适应。
Note 1 sources contributing to the uncertainty include , but are not necessarily limited to , the reference standards and reference materials used , methods and equipment used , environmental conditions , properties and condition of the item being tested or calibrated , and the operator 注1 :构成不确定度的不源包括(但不限于)所用的参考标准和参考物质、方法和设备、环境条件、被检测或校准物品的性能和状态以及操作人员
The thesis firstly summarizes the current research of hdtv test pattern signal , and introduces the hdtv technology , hdtv signal design reference standards , such as smpte international standards and chinese standards for hdtv digital video signal interface of studio 论文首先对hdtv测试信号研究现状进行了概述,并介绍了hdtv技术、 smpte国际标准及国内的演播室高清晰度电视数字视频信号接口等hdtv信号设计参考标准。
Other imperfections are due to the practical limits to which correction can be made for systematic effects , such as offset of a measuring instrument , drift in its characteristics between calibrations , personal bias in reading an analogue scale or the uncertainty of the value of a reference standard 其它非理想性因素是由于对系统效应的修正产生的实际限制，比如测量仪器的误差，两次校验之间的性质偏移，个人读取量数的偏差或者参考标准值的不确定性。
Deformation control of deep excavation pits is firstly introduced in detail , and new conceptions of effective coefficient , effective area , no - effective area and critical line , including the referential criteria and economic - effective measures of deformation control , have been put forward 摘要文中首先对深基坑工程变形控制进行了详细的论述，提出了基坑有效系数、有效区、失效区、临界线的新概念，同时提出了变形控制参考标准和经济有效的变形控制对策。
Meanwhile the elements and attributes of the detail dataset are introduced and the formal and canonical description of the detail dataset are also given by means of xml . for metadata element of media material database , the description of xml makes it possible to exchange with other international reference metadata standards 同时利用xml语言对元数据详细集进行了规范化和形式化的描述， xml的描述使得媒体素材库的元数据元素可以与国际上的其它相关元数据参考标准进行互相转换，在一定意义上实现了开放性。
The thesis is organized as follows . first , i introduce the essential ideas of middleware , the core technologies of streaming media and the standard of multimedia middleware of itu and iso . then , the framework and the main components of directshow are described . after that , i sententiously introduce the main idea of streamingware . the following two chapters are the design and implementation of framework of streamingware and the most important system service - rtp / rtcp . the last is summarization of the thesis 本文先精要地分析中间件的要素，流媒体的核心技术，流媒体中间件的参考标准;然后全面深入的分析directshow的框架组成，运作机理;在这个基础上针对directshow的不足，阐明streamingware的设计思想;然后介绍基础框架的设计与实现以及最重要的系统服务一流式协议rtp / rtcp的设计与实现。
