The approach is that we first calibrate the filter radiometer with cryogenic radiometer and measurement equipment of relative spectral responsivity and then calculate the absolute spectral responsivity . because the drift in blackbody temperature directly influnces measurement accuracy , so we adopt a feedback system to stabilize blackbody temperature through controlling the current of blackbody that improves measurement accuracy greatly 该方法首先要用低温辐射计及相对光谱响应度测量装置对滤光辐射计进行标定，经计算可得到滤光辐射计的绝对光谱响应度；由于黑体温度的漂移直接影响到测量精度，我们采用反馈系统通过控制黑体的加热电流，来稳定黑体温度。
In this paper , the present research and development of the engine vibration control is summarized . in theory , this paper analyzes energy distribution of the engine vibration and discusses the active global - state - feedback control system and the partial - state - feedback control system , and presents the method in selecting the partial feedback states . at the same time , associated with one category of engine , it builds the mathematical model of the engine active control system , provides the lq optimal control strategy and makes a simulation analysis 本文总结了发动机振动控制的研究和发展现状，从理论上，分析了发动机振动的能量分布情况，阐述了发动机的全状态反馈施控系统和部分状态施控反馈系统，并提出了部分施控的状态选取方法，同时结合某具体型号的发动机，建立了发动机的振动主动控制模型，采用以二次型性能指标的最优控制律，进行了整机振动主动控制模拟分析。
By integrating once to chinapt . com , a supplier can offer its customers real - time pricing and availability information , as well as the ability to place and track orders . moreover , chinapt . com s unique " publish instant " supplier content model allows suppliers to publish or update their product content instantly in chinapt . com , instead of having to take time to customize that content for every buying organization and wait for endless response 没有买卖双方的成功，就谈不上电子湾的成功。因此，网上交易的信誉极为重要， "惠特曼就此介绍说， "几年来，我们创制了很多措施保证电子湾是一个安全的交易场所，其中最重要的是创造了一个买卖双方互动式反馈系统。
It advances the following suggestions about this system astern : ( 1 ) to strengthen the subject of higher institutions ; ( 2 ) to prevent from encouraging ; ( 3 ) to carry out competitive tine encouragement management ; ( 4 ) to balance the systematization of encouragement and personalization ; ( 5 ) to combine the satisfaction and the guidance of the need 最后，在以上研究基础上，建立了从需要分析系统到测评与反馈系统的高校人力资源激励管理系统模式并对此系统模式的实施提出了1 、加强高校的主体性。 2 、防止去激励。 3 、进行竞争性激励管理。
This article discusses a concurrent feedback system of customer ideas constructed between integrated services network in inner enterprise and internet platform in outer enterprise . the system can help to collect and analyze customer ideas in time , then provide opinions about the service quality , so the enterprise can monitor their service quality for a long time 本课题通过企业内部的综合业务网及外部的internet网络平台，构建一个用户意见反馈系统，能够使企业及时地收集用户的反馈意见，对企业的服务质量进行长期的监控，由用户的反馈意见来说明企业的服务质量。
3 . based on it , a brand new spe that consists of evaluation preparation system , evaluation execution system , evaluation feedback system , performance amelioration system and as well as evaluation application system , has been reconstructed . this new spe fill up any blank about important tache 根据绩效考评新的定位和对问题的改进思路，本文重新构建了由考评准备系统、考评实施系统、考评反馈系统、绩效改进系统和考评应用系统等组成的绩效考评新体系，填补了该公司在绩效考评体系中关键环节的一些空白。
According to property and function different , differentiate for decision - making system , management system , groom system , harmonious system , superintend and director guides and feedback system , build and govern function of system of system , aggrandizement soundly , make a group each branch , departmental door , various personnel can each doing his own job , ensure the sound development of the group , obtain good economic benefits 按照性质和职能的不同，划分为决策系统、管理系统、培训系统、协调系统、督导和反馈系统、建立和健全管理制度、强化系统职能，使集团各分店、各部门、各级人员能够各司其职，确保集团的健全发展，并取得良好的经济效益。
Fin stabilizer is a kind of active stabilizer , which is designed on the principle of torque counteraction . fin stabilizer applied at present is an angle feedback system which calculate the controlling torque through the fin angle . because the relationship between the lift produced by fin and the fin angle is mainly determined by the hydrodynamic experiment , so there are some defects 目前使用的减摇鳍是一个角度反馈系统，它通过鳍的转角来计算控制力矩，这样就存在一些不足之处，因为鳍上产生的升力和鳍角的对应关系主要靠鳍模的水动力试验来求得。
The implement effect of management system is verified by statistic analysis . it is still planned simply the information program of quality management for oem operation mode . it is specified how to form a close information loop of production , sale and service by computer net , that may avoid quality accidents 本研究还对oem生产方式下的质量管理信息系统进行了初步策划，包括如何运用计算机网络系统使冰箱质量在生产、销售、售后服务等环节中形成闭环反馈系统，实现信息共享，从而避免批量性的质量事故的发生。
