When applying phase-stepping interferometry to measure a surface, distortion will be caused as a result of various error factors especially the phase stepping error from the phase shifter. Even seriously flexuosity can be produced.

用相移干涉术测量物体表面形貌时，各种误差因素特别是相移器移相误差的影响使得表面形貌的测量偏离了实际值，甚至会产生形貌失真的现象。

It has many functions such as conputerized control,frequency conversion speed regulation,fixed-length setting(Fixed-length is divided into servo and stepping two type.The speed is little slower during stepping fixed-length.It can cut paper to maximum 350 gramme of thickness),automatic count,voice-light alarm,electrice eye tracking automatic deviation-correcting etc..

具有电脑控制、变频调速、定长设置（定长分伺服与步进两种，步进定长是速度会慢一点，切纸时最厚只能切到350g）、自动记数、声光报警、电脑跟踪、自动纠偏等功能。

Convenient principle Major person has experienced change the awkwardness that sucks dome light bulb: Stepping on a table, stepping a chair, hold one's head high 90 degrees, carry double arm overdoes 2.5 meters tall taller even ceiling.

方便原则大部分人都经历过更换吸顶灯灯泡的尴尬：踩着桌子、踏着椅子、昂首90度，抬双臂过头到2.5米高甚至更高的顶棚。

Major person has experienced convenient principle to change the awkwardness that sucks dome light bulb: Stepping on a table, stepping a chair, hold one's head high 90 degrees, carry double arm overdoes 2.5 meters tall taller even ceiling.

In addition, this article took the isoclinic information which unwrapped already into isochromatic formula to get the correct retardation. This method might not get the form of arc-tangent because there are not output quarter-wave plates in three and six phase-stepping methods. Therefore, this paper corrected it by load-stepping method.

另外，为了使相位展开技术能顺利完成，进而得到相对的延迟量，在修正等色线包裹相位图中的不连续点时，本文使用之方法是将修正完的正确等倾线数值带入等色线公式中，此法在三场与六场中因为少掉了输出的四分之一波板，造成公式的结果使得条纹角度分布非反正切形式，因此需另外使用负载相移法来做修正。

In view of the present major problems of the open-loop control system for economic CNC lathe with stepping motor as feed motor, a newtype of closed-loop control system for stepping motor has been presented in the paper.

针对目前以步进电机驱动的经济型 CNC车床开环控制系统存在的主要问题，提出了一种新型的步进电机闭环控制系统。

The step motor can receive digital signal directly and has the ability to response outer environment immediately and has no accumulation error, which often is used in driving system. In this driving system, open-loop control system is composed of stepping motor, which can satisfy the demand not only for control precision but also for the target of economic and practicality. On this basis , the analysis of stepping motor in power calculating and style selecting is also given.

由于步进电机能够直接接收数字量，响应速度快而且工作可靠并无累积误差，常用作数字控制系统驱动机构的动力元件，因此，在驱动装置中采用由步进电机构成的开环控制方式，这种方式既能满足控制精度的要求，又能达到经济性、实用化目的，在此基础上，对步进电机的功率计一算及选型问题经行了分析。
