derived estimate造句

• Class uses a least - squares criterion for deriving estimates of what the y intercept and slope parameters should be
  类使用最小二乘法准则推导出y轴截距（ y intercept ）和斜率（ slope ）参数的估计值。
• By computing the between two resolution units , we can estimate terrain azimuthal slopes and derive estimate of terrain elevation . the terrain contour is determined uniquely by ay / from azimuth slop on range gates . american began to study p - sar three - dimensional images technology in 1990s
  Schuler已经证明，对于一个均匀分布场景， sar图像上两个相邻分辨单元的极化椭圆方向角偏移量，与地形方位向坡度的对应关系是线性唯一的，地形方位向的倾斜度可以通过解唯一地被测定。
