| 1. | The sun , for example , takes about 230 million years to go around its elliptical orbit
例如，太阳走完椭圆轨道一周约需2亿3000万年。 |
| 2. | The engine operated for 63 seconds . the elliptical orbit was changed to a near circular orbit
飞船变轨，变轨发动机工作了63秒，使原来的椭圆形接近圆形。 |
| 3. | Orbit adjustment began . the engine operated for 63 seconds . the elliptical orbit was changed to a near circular orbit
飞船变轨，变轨发动机工作了63秒，使原来的椭圆形接近圆形。 |
| 4. | If the satellite has an elliptical orbit , the result is a spiral wave , a miniature version of the pinwheel pattern of our galaxy
如果卫星的轨道是椭圆的，就会产生螺旋波，就像是银河系纸风车形状的缩影。 |
| 5. | A regional satellite navigation system which is made up of geosynchronous satellites and synchronous satellites with elliptical orbit is proposed
摘要提出了一种用静止卫星和同步椭圆轨道卫星构造的区域卫星定位系统。 |
| 6. | This planet , unlike the other planets in our solar system , has an elliptical orbit and moves clockwise rather than counterclockwise
这颗行星，不同在我们太阳系的其他行量，是椭圆形轨道，顺时针方向移动，而不是逆时针。 |
| 7. | A elliptical orbit may occur if the small body has an high velocity when close to the large body , and a very slow velocity when far from the large body
如果小的天体离大天体很近时以很高的速度飞行的，较远时以很慢的速度飞行，就形成一个椭圆的轨道。 |
| 8. | Most of the meteoroids of the leonid meteor stream concentrate in an elongated thin ribbon - like region . the stream orbits around the sun in an elliptical orbit with a period of about 33 years
狮子座流星群聚集于一条狭长的区域内，以极为椭圆形的轨道环绕太阳运行，周期约为 |
| 9. | 2 . based on the spaceborne sar theory , an elliptical earth model and an elliptical orbit model are proposed , which have some advantages over the traditional circular ones
2 .基于星载sar的基本理论,给出了一种进行星载sar回波信号模拟的椭圆地球模型和椭圆轨道模型,它们优于传统的球地球模型和圆轨道模型。 |
