The second one : we studied the effect of temperature on performance of lds . it was found that threshold current increase exponentially outpower and slope efficiency decrease parabola and exponentially respectively . coefficient of temperature shift is 0 . 24 / k , wheras characteristic temperature also decrease with rise of temperature 研究了温度对激光器各参数的影响,随着温度的增加,阈值电流呈指数增加,输出功率和斜率效率分别呈抛物线和指数关系递减,同时特征温度也减少,波长随温度的漂移系数为0 . 24nm ,并且总结了一些温度和结构设计方面的关系。
By means of temporary stability of combining drift coefficient of angle sensor and through missile rotating two - position measurement , measuring rotating angle between the two positions by vertical sensitive axis x , and sensing the changes of ground velocity component between the two positions by horizontal sensitive axis and z , the position of the component is determined to realize the azimuth alignment before launch of tactical missile 角敏感元件漂移系数具有短期稳定性,通过转弹前后两位置对组合的测试,垂直敏感轴计测转弹过程中两位置之间的转角,两水平敏感轴敏感计测地速分量在前后两位置的变化,由此计算出部件当前所在方位,从而实现战术弹射前的方位对准。
