In the course of getting acquainted with a varied world , whirling on through the ever changing phases of it , he had learned a rule of conduct which was to the effect that when one played a strange game , he should let the other fellow play first 他认识多姿多彩的世界,曾在它于变万化的局面里旋风般前进。在那过程中他学会了一种行为准则,大体是:凡是新花样都让别人先动手。
At first , the dissertation author analyzes the measure method characteristic of three - phase three - line system and three - phase three - line system by power measure principle , and analyzes all kinds of power theft way , then concluding them to five styles : voltage style , current style , change phase style , enlarge error style , shunt style 论文从电能计量原理和准确计量方法入手,简要介绍了电能计量的发展历史,单相电路和三相电路的各种计量方式。其中重点介绍了三相三线经电流互感器和电压互感器接入式和三相四线只经电流互感器接入式这两种计量方式。
In sensored case , the theory of hall signal checking ahd how to change phase are discussed . in sensorless design , using a single line resistance measure phase current and estimating rotor position are brought forward by analyse associate codes . at the same time , problems and solution which meet in task are mentioned in report 在有位置传感器方案设计过程中,详细讨论了霍尔位置信号检测原理和换相控制原理以及实现过程;在无位置传感器方案设计中,提出了单电阻电流检测原理和位置估算的算法,并且对相关的软件代码进行了分析。
The freezing phase refers to the process to understand the needs for change , to inspire unsatisfactory to realism and to breed the desire to spurn the old . at the same time , the influence of the change must be understood and a secure sense must be created . the change phase is a process transiting from the old stage to the new one , which points out the direction of reform , applies transformation and guide the staff to form new attitude and behavior 卢因认为任何组织的发展都要经过“解冻?变动?再冻结”三个阶段:解冻是指人们认识到变革需要的过程,在此阶段应激发人对现实的不满,并产生摒弃旧态度、旧行为方式的愿望,同时使人们了解变革的影响,创造心理上的安全感;变动是旧阶段向新阶段的过渡,它指明变革方向,实施变革,使职工形成新的态度和行为;再冻结是指固定新行为和新态度,不让它进一步变动的过程,以防止恢复到解冻前的状态。
Study on the laser scanner is very important since fluctuate of rotating speed of the motor , wobble of the shaft of the laser scanner , tremble introduced by motor changing phase , shake generated out of dynamic balance , turbulence introduced by the deflector rotating at high speed have an influence on rotating shaft and light beam so as to decrease quality of the laser imagesetter 转速的波动、扫描器主轴的晃动、电机换相过程中的抖动、动不平衡产生的震动、转镜高速旋转产生的湍流对转轴和光束的影响等诸多因素,直接影响激光照排的质量。所以,对转镜式激光扫描器的研究有十分重要的意义。
