Examples
- The absorption characteristics was that the surface plasma absorption peak appeared around 570 nm shifted to a short wavelength and strengthened as the cu composition increased . but the maximal shift range of the absorption - edge preponderated over 500 nm , and leaded that the dipolar plasma resonance absorption peak were covered up and gradually disappeared in the absorption spectrum . we theoretically explained the mechanism of the modulating action
实验观察到cu表面等离子体共振吸收峰位在570lun附近的吸收边频移量超过了500nln .理论分析表明，吸收峰位的移动主要源于偶极共振，而峰形的宽化主要由纳米粒子的表面效应和量子尺寸效应引起 - Based on the modularized asi , cascade inverter topology structure and modulation mode is introduced in this paper . comparing with several control strategies such as single closed - loop feedback and dual close - loop instantaneous value feedback , the voltage - current dual closed - loop control strategy , which is the voltage effective value feedback and inductance current instantaneous value feedback , is adopted
针对级联逆变器讨论其pwm调制技术,在比较几种pwm调制技术的基础上,对该级联逆变器采用倍频载波移相调制技术,其输出不含载波谐波,边频谐波次数比二阶和三阶调制的边频谐波次数提高一倍,等效开关频率也提高一倍。
