Examples
- By changing the composition of n and in , we can adjust the band gap of galnnas to about 1 . 3 m and also make it lattice matched to gaas . it makes the resonant cavity enhanced ( rce ) infrared photo detector based on gaas become possible
通过调节n和in的组分，可以使gainnas的带隙在1 . 3 m左右，同时使得它与gaas晶格匹配，这为实现gaas基的共振腔增强型( rce )红外探测器和激光器提供可能。 - Galnnas is a very promising new material for infrared lasers , photo detectors , solor cells and optical integration . it has much more advantages than galnasp because much better electron confinement can be achieved in this system , thus much higher the laser ' s characteristic temperature will be
由于gainnas在红外激光器，光探测器，太阳能电池以及光集成等方面巨大的应用前景和相对于gainasp的优越性，人们对ganas及gainnas的研究在最近两、三年里蓬勃发展。 - Summarizing the development statement of monitoring technology for bridge , based on principle of pulse laser ranger detection and fiber - optic strain measurement , in view of the problem affected by single - chip inherent feature , integrating the goodness of cpld device and single - chip , using a / d converter to measure the count quantization error , a strain measurement system is worked out . the above system chiefly consists of light source , optic fiber sensor , photo detector and signal processing circuit
本文综述了国内外桥梁监测技术的发展概况，在深入研究脉冲激光测距和光纤应变测试原理的基础上，针对单片机固有计数频率低、计数量化误差大和延时不固定等不足，结合cpld计数频率高、延时小而固定和单片机控制功能强的优势，并采用模数转换技术设计计数量化误差测量电路，提出了基于激光脉冲时间测量法的光纤应变测量的方案。
