angular shift造句

• Because mercury is so far from earth, the angular shifts were too small to be measured accurately
  因为水星离地球太远，角差太小而无法准确测量。
• This angular shift, called the parallax of venus, would provide a measure of the distance between earth and venus because the two quantities are inversely proportional to each other
  这个角差称为金星视差，可以做为地球和金星距离的指标，因为两个数值互成反比。
• Because each path takes the form of a chord ? a straight line connecting two points at the edge of the sun's disk ? astronomers could measure the angular shift between the paths by comparing the durations of the transits
  因为每条路径都是一条弦（连接太阳盘面边缘两点的直线），天文学家便能比较凌日持续的时间，而计算路径间的角差。
