核運載工具 的英文怎麼說
中文拼音 [héyùnzǎigōngjù]
核運載工具
英文
nuclear delivering vehicle-
As a new generation of micro - satellite based on micro - electro - mechanic system ( mems ), pico - satellite, in virtue of its low weight ( 1kg or lighter ), is unburdened from high - cost large sending sets. thereby research of pico - satellite can be progressed with much lower cost without huge experimental establishments and wide - span workshops so that institutions, mostly universities, became the main researching force. besides reduced expenses, another advantage of research in university laboratories is the potential high privacy
皮型衛星是新一代以mems技術為核心的微小衛星，由於質量很輕（ 1kg以下） ，可不使用高成本的大型運載工具進行發射，其成本可比一般衛星大大降低；此外，皮型衛星的研製將不再需要大型的實驗設施和高跨度廠房，因此目前大學等研究機構是研製皮型衛星的主要科研力量，在大學的實驗室里研製皮型衛星，可以降低它們的研製費用。This paper sums the situations and trends of domestic and international engineering machinery firstly, discusses the demands and implements of intelligent and long - range monitoring and controlling, and constructs a three - layer model of the engineering machinery long - range monitorin and control system : the front unit control systems, the machine - mounted monitoring system and the long - range control center ; proposes a kind of structure of embedded system based on c / os - ; dissects the characteristics, structure, operation and schedule principle of c / os -, modified the kernel, and improves dependability of the schedule algorithm ; designs the hardware in detail : the microprocessor at91rm9200, the store unit, the serial interface, the human - computer interaction interface, the can bus control module, the debug interface and the reset circuit etc. ; on this basis, succeeds in transplanting c / os - to the system, sets up the operating system framework, designs the driver, sets up the institutional framework of upper user ' s application, provides the method and concrete application process of the graphical user interface module based on c / os -. the system designed in this paper, not only has the functions of local control, friendly human - computer interface, but also has various interfaces which make the system can be managed by the long - rang center
本文首先綜述了國內外工程機械行業發展的現狀和趨勢，闡明了實施工程機械智能化及遠程監控的意義和需求，並為此構建了工程機械遠程監控系統三層結構模型:前端單元控制系統、車載監控系統和遠程監控中心;提出了一種基於c / os -的嵌入式車載監控系統構建方案;深刻剖析了c / os -的特點、內核結構、運作機理、調度演算法，在此基礎上對其內核進行移植前的必要修改，並對其調度演算法進行了可靠性改進;對構成嵌入式系統硬體的各個主要部分:嵌入式微處理器at91rm9200 、存儲單元、串列介面、人機交互介面、 can總線控制模塊、調試介面以及復位電路等做了詳細的設計;在此基礎上，成功地將c / os -實時內核移植到本文研發的嵌入式硬體系統中，建立了車載監控系統的操作系統體系結構，編寫了該操作系統的底層硬體驅動程序，建立了上層用戶應用程序的組織結構，並給出了圖形用戶界面模塊化應用程序在c / os -操作系統上的建立方法和具體應用過程。Information from 2003 details the construction of a terrorist cyanide - based chemical weapon that can be made with easily available items, requiring little or no training to assemble and deploy
報告說，隨著核技術、生化技術和彈道導彈技術越來越容易得到，制止大規模毀滅性武器及其運載工具的擴散也越來越困難。
