If can utilize hall ' s component to measure displacement under the condition of the simple magnetic field , increase the range of measuring ; it inertia little , merit that exposed to make it function in the measurement of vibration and in various kinds of displacement , become a kind of displacement sensor with fine performance . it can solve this difficulty to adopt the feedback servo mechanism 若能在简单磁场的条件下利用霍尔元件测量位移，增加测量范围；它惯性小、非接触的优点将使它在各种位移与振动的测量中发挥作用，成为一种性能优良的位移传感器。采用反馈随动机构可解决这个困难。
This paper addresses the novel on - line flaw detection method for continuous and non - contact detection adopted in this detection system , which completes flaw detection by measuring the leakage current when forcing the enameled wires to pass through a high - voltage dc electric field . this paper also studies and designs the sensor for the detection system 文章着重论述了本系统中所采用的一种新型的非接触的直流高压电场漆膜连续性缺陷在线检测方法，其原理是产生足够的高压电场，让高速行走的漆包线从电场中通过，通过测量其泄漏电流来了解漆包线上漆膜连续性缺陷的情况。
The most significant advantages of the electrostatic suspension are as follows : ( i ) it keeps the characteristic elegance of the conventional electric suspension methods mentioned above ; ( ii ) it is capable of realizing electrostatic levitation of conductors , semi - conductors and non - conductors , such as the liquid crystal display ( lcd ) , the compact disk ( cd ) , the silicon wafer and so on ; and ( iii ) it provi des the possibility of implementing non - contact conveying or manipulation of precision objects on the basis of suspension 利用该悬浮方法可以广泛实现导体(如金属片) 、半导体(如硅wafer ) 、常规绝缘体或电介质(如lcd片、 cd片、玻璃片、纸片)等悬浮，进而对其进行非接触的无损操作。与常规电悬浮和磁悬浮相比，静电悬浮的突出优点是不受悬浮体的磁性和导电性的制约，因而应用领域更加广阔。
