This text studies carefully the state of the crane and monitors the dependability design how the result guided the crane too , design basic theories and basic procedure frame after describing the life - span of dependability of the crane , have told the basic demand that the life - span of dependability of the crane is designed at present 本文研究了起重机状态监测结果如何处理来满足起重机可靠性设计的要求,论述了起重机可靠性寿命设计基本理论和基本流程框架,讲述了当前起重机可靠性寿命设计的基本要求。
Contraposing the main problems existing in construction project management presently : awful in scientific capability , low in efficiency , modes of informational management in several key stages of the process of construction project management are studied carefully : [ 1 ] measuring the information in quantity is the foundation of the construction of the information management system . a method of measuring the information in quantity , the work break structure ( wbs ) , is introduced , and an analysis of how the wbs contributes to the comprehensive planning and comprehensive controlling is made 主要针对当前建设工程监理中存在的主要问题:科学性差、效率低,就建设监理工作中几个关键环节的信息化管理模式进行了深入的研究: ( 1 )信息量化是构建信息管理系统的基础,对信息量化方法? ?工作分解结构( wbs )的基本原理进行了详细的阐述,并就wbs如何在项目的综合计划和综合控制中发挥作用进行了分析研究。
It study carefully the distortion of the remote sensing imagery , the rectification of the radiant quantity , the rs image strengthen and the color fusion . based on these achievements above , we do experiment on the differential rectification , the rs image fusion , the object determining and the exchange for the different format data , propose the plan and flow chart of the terrain map rectification by the rs imagery . we demonstrate the method for the target location and the direction outside by the rs imagery and how to select the reference point and read the information of the rs imagery 本文阐述了利用航天遥感影像进行1 : 25万地形图数据库更新的必要性和可行性,在对spot和landsat遥感影像特性进行分析的基础上,对航天遥感影像的系统变形、辐射量校正和影像增强与彩色融合等内容进行了认真研究,并在此基础上对航天遥感影像数字微分纠正、影像融合、地物判读、数据库数据格式转换、基于遥感影像的地形图修测等方法进行了具体试验,提出了利用遥感影像进行地形图修测的具体方法和作业流程。
