Connecting with different peripheral devices , the circuit can also have the functions of short circuit protection , soft start and four kinds of dimming control 通过各种不同的外围应用电路能实现短路保护、软起动及四种调光控制方式,应用非常灵活。
Flexible dimming control utilizes either an analog control signal or direct digital pwm control without external rc filtering . this also increases dimming accuracy at low brightness levels 电路采用灵活的调光控制方式,既可输入模拟控制信号,也可直接输入数字脉冲宽度调制信号而不需要外置rc滤波器。
In this thesis , we described the principle of photon modulation , the model of photon induced careers and the model of carrier - induced index change . we analyzed the effect of 3 - d structure of waveguide to the lightwave in the waveguide 本论文首先阐述了光控制光开光的原理、光生载流子的模型,以及光生载流子影响折射率变化的模型,分析了三维波导的结构对传输光波的影响。
But the speed of photon induced optical switch can be several ps , and it is independent to polarization . with the optimization of its structure , its performance can be applicable . so study of photon induced optical switch has science research value and application value . 光控制光开关的开光速度可以达到ps量级,并且对偏振的敏感性不高,通过对开光结构的设计和优化,其性能指标也可以达到实用要求,因此对光控制光开光的研究具有实际的理论意义和应用价值。
The gasman was at his post amid an intricate arrangement of cocks ; a fireman , leaning against the side lights , was craning forward , trying to catch a glimpse of things , while on his seat , high up , the curtain man was watching with resigned expression , careless of the play , constantly on the alert for the bell to ring him to his duty among the ropes 管煤气灯的工人一直忠于职守,呆在装置复杂的煤气灯光控制板旁边一个消防队员倚在一根撑架上,脖子伸得长长的,想看看演出拉幕工坐在高处的一张凳子上,一直守在自己的岗位上,一副尽心尽责的样子,他对演出的戏一无所知,他在等铃声一响,就去拉幕绳。
