Eddy current nondestructive testing ( ecndt ) is widely used to detect the thinness and defects of the sample , because of its characteristics of non - contact , high sensitivity and ease of detection . the principle of ecndt is that : when a probe coil with the ac exciting source is put near a sample , eddy current will be produced in the sample which will conversely affect the impedance of the coil according to the farad theorem . any un - uniformity in the sample will change the impedance of the coil and the output voltage 渦流無損檢測技術具有靈敏度高、檢測速度快、非接觸等特點廣泛應用于厚度檢測和缺陷探傷,它的原理是當載有交變電流的檢測線圈靠近金屬導體時在導體中產生渦流,該渦流又影響原磁場,使得線圈的阻抗和感應電壓發生變化,通過分析阻抗或感應電壓的變化來獲得被測導體的信息。

Sem and tem analysis show that the sample co - doped by nickel and titanium has nano - pellets with morpha like snow and great surface , which the initial discharge capacities in organic electrolyte reached 155 . 8mah / g and which were more than theoretic one farad electron discharge capacities ( 148mah / g ) . during the charging and discharging cycle , the change rate of the crystal volume was only 0 . 233 % and the sample showed long cycle life 樣品在有機電解液的初始電容量( 155 . 8mah / g )大于理論1f電子放電容量( 148mah / g ) ,通過充放電前后xrd衍射圖顯示,放電前后晶胞體積變化僅為0 . 233 ,樣品循環性能好。

Mems ( micro electromechanical system ) has become one of the most rapidly development technologies . along with the rapid development of mems techniques , capacitive sensor is used widely whose capacitance changes small , which has put forward the new request to the measurement technique . the common measure for capacitance measurement is that convert capacitance to voltage , electric current or frequency . the area of polar plate of the capacitor becomes smaller and smaller , and the total capacitance of micro capacitive sensor is usually several pico farad only . as a result , its change amount is smaller Mems ( microelectromechanicalsystem )近年來發展最快的技術之一,隨著mems技術的快速發展,電容式加速度計的電容變化變化量越來越小,對檢測技術提出了新的要求。在電容式傳感器中,常用電容檢測電路是將其轉換為電壓、電流或者頻率信號。目前的微型電容傳感器的極板面積變得越來越小,電容總量只有幾個pf ,變化量就更小。

This meets the headquarters address : american new york farad abundant 40 street 135 - 28 3 buildings a place ; asian and pacific headquarters : in hong kong around the city multi - advantage street 9 business building ten buildings 本財團總部地址設在:美國紐約法拉盛40街135 - 28號3樓a座;亞太區總部設在:香港中環城多利皇后街9號中商大廈十樓。

We can store electrical energy in to metal plates seperated by an insulating medium . we call such a device a capacitor , or a condenser , and its ability to store electrical energy capacitance . it is measured in farad 兩片絕緣的金屬板之間能夠存儲一定的電量,我們稱這種裝置為電容器,它的功能就是具有一定的電容量,其衡量單位是法拉。

3000 hours . lower voltage high capacitance cdf farad - grade aluminum electrolytic capacitor . well suited for use in super car audio systems , industrid robots , telecommunication equipmemt of dc or pulse circuits 3000小時,低電壓高電容量法拉級cdf ,廣泛用于精密汽車聲頻系統、工業機器人,電信設備的直流電或脈動電路中。

In the modern electricity metrology standards , standard capacitor is considered as the best phsical standard which can be used to reappearance of the capacitance unit ? farad 現代電學計量標準中,標準電容器被認為是復現電容量值單位?法拉最好的實物標準。

Cold was farad in an out of the way village in the mountains , and soon a good road and airfield were built 在一個偏僻的小山村發現了金子,很快一條好的公路和飛機場建造起來。
