结果表明:偏转矢量喷管的壁温沿周向有明显变化,沿偏转方向的壁温较低,相反方向的壁温较高。
The results show that the temperature of deflected vectored nozzle varies apparently along the circumference, temperature along the deflecting direction is lower than that of the opposite direction.
高分辨 距离像(HRRP)是宽带雷达获取的 目标散射点子回波沿雷达视线方向的投影矢量和。
High resolution range profile(HRRP) is the projection vector sum of target scattering point echoes acquired by wide-band radar along the direction of radar line-of-sight(LOS).
It's good to have a vector pointing in the radial direction of length one.
所以引入这么一个模长为 1,方向沿圆心向外辐射的矢量作用很大
er is a vector at each point of length one pointing radially away from the center.
r 是一个模长恒为 1 的矢量,方向沿半径向外
