Saturnian

An international team of scientists have discovered that Saturn's ultraviolet auroral glow pulsates in time with its radio wave emissions, possibly signalling a ticking over of each Saturnian day.

近来有国际科学家小组发现，土星紫外极光频率与其射电脉冲频率一致，也许可以据此来确定土星一日的长短。

This paper establishes the differential equations of motion of space explorer according to the Newton's Laws of Motion and the universal gravitation, computes the flying orbit of Saturnian explorer, taking the Saturnian explorer as the computational example and using accurate numerical integration method.

根据牛顿第二定律和万有引力定律，建立了空间探测器的运动微分方程，并以土星探测器为例，利用精确的数值积分方法对其轨道进行了设计和计算。

In the design and computation of orbit of Saturnian explorer, the author fully utilizes the gravitational force of some celestial bodies, thus reducing greatly the launching conditions.

在土星探测器的轨道设计和计算中，充分利用了有关天体的引力机动，有目的地使探测器飞过一系列行星来增加探测器的能量，从而大大降低了探测器的发射条件。
