Furrow - ridge - opener is the main working part of water - application - furrow seeder , the key requirement to the new design is the furrow opening , ridging , watering and fertilizing of soil completed at a time 起垄开沟器是灌水沟播机的主要工作部件，它需同时完成起垄、开沟、灌水、施肥等多项工作。
During drilling operations , power is directed to the various machine functions by a pump power drive gearbox . the actual configuration is dependent on the drilling process 发动机的动力通过齿轮箱以及其驱动的液压主泵被传递到各个工作部件,实现对各个钻机功能操作.用户可根据实际的要求灵活选择设备配置
Spade is the type of farm machine operator . many moulding - making method were tested in the research . common bi - spade , plain bi - spade and half - sweeps shovel ? solid mouldings were built 以铲式部件为农机工作部件的代表，尝试了各种铲式部件的造型方法，建立了双翼平铲、双翼通用铲、单翼平铲的实体模型。
The primary function of the software are confirming the fundamental dimensions of the ditcher , optimizing the volume of reducer , carrying through dynamic , real - time simulation to working part 该软件的主要功能为：确定新型蓄水保墒机具机构基本尺寸；对减速箱的体积进行优化；对工作部件的运动进行实时的、动态的模拟。
As the key part of synthetic jet technology , the synthetic jet actuator can work without fluid feeding and has momentum flux but no mass flux . since it only needs electricity when works , it can be controlled easily 合成射流激励器作为该技术的关键工作部件，具有无需流体输送，净质量流量为零，动量不为零的特点，而且合成射流激励器工作时只需要电能，易于实现电参数控制。
The exchanging middle ware is adopted to isolate the exchanging gateway from the trade user ' s server when they are exchanging the data . the exchanging middle ware is the unique information channel between the exchanging gateway and the trade user ' s server , they cooperate with the exchanging gateway , they supply the service of data handing to the exchanging middle ware and share the work 在本文中采用交易中间件，将交易网关和商户从数据交换上隔离开，交易中间件是商户服务器同交易网关的唯一信息通道，是交易网关的协同工作部件，为交易网关提供数据处理服务，分担一部分处理任务。
With the deveiopment of hydraulic technology , hydraulic system and hydraulicequipment are more complicated , hydraulic technology is more widely and morecomp1icatedly used in agricultural machine and their malfunction is more difficu1t to bedetected . fault diagnosis of hydraulic system is not as apt to be observed as that of themechanical equipmeflt or is not as easy to be detected as that of electric equipmeflt bymu1tipurpose meter or other meters . flux meter gage and pressure gage ca n ' t meet the needof fault diagnosis for hydraulic system because its working medium and workingcomponents are hiding inside the sealed vessel 随着液压技术的发展，液压系统及液压设备越来越复杂，液压技术在农机上的应用也变得广泛而复杂，农机液压系统的故障诊断也越来越困难，液压系统的故障诊断不象机械设备那样直观，也不象电气设备那样通过万用表等仪器测得，液压系统的工作介质和工作部件都在密闭的容腔内，流量计、压力表等测量仪器远远不能满足故障诊断的需求。
5 the modernizing technical method is applied and mcs - 51 is made as controller of no - tillage transplanter to control all of the execute parts of the equipment automatically by single chip microcomputer through watching these key parts by " some transducer . in this system , the working state of this equipment is online show by calculating the number of transplanted plug seedlings ; and the broken - down occurrence can be predicted by alarming system during transplanting plug seedlings ; at last , anti - jamming system is designed to raise the reliability of this system further by the method of combine the software with hardware together in the condition of achieving all functions in transplanting plug seedlings 5采用现代化技术手段，以mcs - 51单片机为免耕栽植机的控制器，通过对各工作部件的计算机监控，实现了免耕栽植机所有执行部件的计算机控制；通过对钵苗栽植数的统计，实现了机器作业情况的在线显示；通过报警系统的设计，实现作业过程故障的及时报警；最后，本控制系统实现以上功能的基础上，采用软件形式与硬件相结合的办法，对其抗干扰性进行了设计，进一步提高了系统的工作可靠性。
We also give the reliability analysis of cold - , warm standby repairable system of two components with continuous lifetime switch and priority , under the condition that the operating time and maintained time of the two components and the lifetime and repair - time of the switch are all exponential distributions . all the variables are independent , and the lifetime of operating components have nothing to do with its maintained time , and the failure components and switch can be as good as new after repair 对于由两个不同型部件组成的、有优先权的、开关寿命为连续型随机变量的冷、温贮备可修系统，本文在两部件的工作时间、维修时间以及转换开关的寿命和修理时间均服从指数分布、所有随机变量均相互独立、工作部件的寿命分布与其贮备时间无关、故障部件和转换开关均可修复如新的情况下作了研究。
