機器極低壓 的英文怎麼說
中文拼音 [jīqìjídīyā]
機器極低壓
英文
melv = machine extra low voltage-
Thus, it is difficult to find the voltage reference for the harmonic analysis. since acem are always operated near to the synchronous speed, the frequency of the excited voltage is very low, even to zero. therefore, this is the power harmonic suppression study of a complicated power supply system, in which the about harmonic general theories and methods are all inapplicable
現代交流勵磁電機（ acem ）採用電力電子變流器作為勵磁裝置，其勵磁電壓諧波含量豐富，難于獲得諧波分析所需的電壓基準，同時交流勵磁電機經常工作在同步轉速附近，致使勵磁電壓頻率極低甚至為直流，通常的諧波檢測方法和理論都無法適用，因而這是一種目前尚未深入探討過的復雜供用電系統電力諧波抑制問題的研究。How to further improve the luminous efficiency, brightness, life length and operating voltage of organic light - emitting diodes ( oleds ) is still in research
如何進一步提高有機發光二極體（ oled ）的發光效率、提高發光亮度、延長器件壽命、降低工作電壓還處于不斷研究中。Compared with the extension actuation mechanism of piezoelectric materials when electric field and poling direction are along the piezoelectric layer thickness, the shear actuation mechanism of piezoelectric materials when applied electric field and poling direction are perpendicular can induce lower stresses in actuators, which can reduce the possibility of debonding in actuators boundaries
與外加電場與極化方向平行於板厚度的壓電材料的拉伸作動機制相比，外加電場與極化方向垂直的壓電材料的剪切作動機制可以在作動器內產生較小的應力，從而降低作動器邊界產生分層破壞的危險。
