椭圆离心率

TCECS分辨率的影响因素较多，主要有椭圆的离心率、狭缝的宽度、光源没在椭圆的前焦点上、探测圆轴线没有通过椭圆后焦点、瞄准对中等引起的误差。

There are many influencing factors for resolving ratio of TCECS , which are elliptical eccentricity , aperture width , light source not locating in the front focus of ellipse , the axis of detector does not pass through the back focus , aiming and alignment error .

作为理论天文学家，巴蒂金试图将一颗行星安放其中。这打散了柯伊伯带中的不少天体，但形成的椭圆轨道的离心率依然不够大。

Dr. Batygin , a theorist , tried placing a planet among them , which scattered some Kuiper belt objects , but the orbits were not sufficiently eccentric .

变位后的齿轮节曲线仍然是一对共轭的椭圆，其离心率与变位前椭圆节曲线的离心率相同，而大小的相对变动量等于中心距的相对变动量。

The pitch curves of gear after modification are still a pair of conjugate ellipse with the same eccentricity as that of elliptical pitch curves before modification , and with the amount of relative variation of their size equals to the amount of relative variation of centre distance .

拖动此形状，可添加一个由直径定义的圆。椭圆中允许调整离心率。

Drag to add a circle defined by diameter . Adjustable eccentricity allows for ellipse .

根据椭圆的几何关系，研究了光谱相对孔径与椭圆的离心率和谱线探测角之间的关系，它随X射线波长增大而减小。

The relation between the spectrographic aperture ratio and elliptical eccentricity , spectral angle is also analyzed according to the elliptical geometry , it will decrease when the x-ray wavelength increases .
