4) raising point
抬头点

在光电效应法测普朗克常量的实验中,用3阶逐差确定光电管对各种单色光的伏安特性曲线的抬头点,可以精确到0。
5) nose up pitching moment
抬头力矩
1.
The principle of the increase of the nose up pitching moment by opening the drag plate for an airplane has been studied in NH 2 wind tunnel.
在NH-2风洞中对某机放减速板产生较大抬头力矩的机理进行了研究,通过减速板分离涡场的测量和测力试验表明,抬头力矩主要是由减速板分离涡在平尾处产生较大的诱导下洗角所致,诱导下洗角沿机身轴线向后逐渐减小,减速板前移可以消除抬头力矩。
