發現有些小油滴可能由於摩擦作用而帶了電。Thus, glass becomes positive, while the silk with which the glass was rubbed becomes negative.
例如，玻璃與絲綢摩擦時，玻璃帶正電，而絲綢帶負電。The research of macro friction phenomena is a synthetically analytical method based on test. however, in micro world, the friction force and vertical press are all minute, which brings difficulties to test. when high measure precision is required, the resolution and sensitivity will be higher and not easy to obtain
宏觀摩擦現象的研究一直是採用以試驗為基礎的綜合分析方法，對于微摩擦研究，由於微機電系統結構體積比較小，且所測摩擦力和正壓力亦為微小量，這就給微摩擦測試裝置的實現帶來了很大的困難。Diamond is a remarkable material due to its special crystal structure, which shows high hardness, low friction coefficient, high thermal conductivity, high optical transparency, low permittivity and high band gap etc. cvd diamond films are widely used in mechanical coating, heat sinks, optical window, semiconductor devices and other application fields because of its low price and high performance
金剛石的特殊晶體結構使其成為一種性能優異的功能材料，它具有高硬度、低摩擦系數、高熱導率、高透光率、低介電系數和高禁帶寬度等性質。化學氣相沉積制備金剛石膜成本低、質量高，廣泛應用於工具塗層、熱沉、光學窗口、半導體器件等方面。However, the traditional dc motor uses brush so as to switch the phases, so there are relative mechanical frictions. then it comes out many fatal failing, such as yawp, spark, wireless disturb, etc. what " s more, its making cost is high, its maintain is also difficult, therefore its application is greatly limited
直流電動機具有運行效率高和調速性能好等諸多優點，但傳統的直流電動機均採用電刷，以機械方法換向，因而存在相對的機械摩擦，由此帶來了噪聲、火花、無線電干擾以及壽命短等致命弱點，再加上製造成本高及維修困難等缺點，從而大大地限制了它的應用范圍。No sooner were the pieces of silk rubbed against the glass rod than electricity appeared on the rod.
用絲綢摩擦玻璃棒，棒上就帶電。Study on testing the quantity of frictional static electricity of rdx
炸藥摩擦靜電帶電量測試研究This machine has great feeding ability, easy to be regulated, can be fed with fixed quantity under control of time delay relay ; it is divided into one - way feeding and bidirectional feeding in terms of feeding direction, suspending type and seating type in terms of installation ; in order to assure precision of feeding, roller encapsulation is equipped to increase frictional coefficient between adhesive belt and rollers ; the rectangle discharging mouth has large dimension which can prevent humping up materials ; this machine has close structure, reliable application and can be easily repaired because it has many similar parts with belt type conveyor
該機給料能力大，調節給料量方便，又可在時間繼電器的控制下定量給料按給料方向該機可分為單項給料和雙向給料，按安裝方式又分為吊掛式和座式為了保證給料的精度，主動滾筒包膠，以增加膠帶與主動滾筒的摩擦系數料倉矩形卸料口的尺寸大，物料不易起拱該機結構緊湊，使用可靠，它與帶式輸送機有許多通用部件，故維修方便。Contact electrification between metals
