Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

347关于宇宙日益扩大进化的冥想：新月期的月亮，即使在近地点也看不见。从地表向地轴挖掘纵深五千英尺的圆筒状垂直轴，一个观察者呆在轴底儿上，就连白昼也辨认得出那漫无止境、网络状、亮光闪闪、非凝结性的银河。天狼距地球十光年（五七、000、000、000、000英里）；体积大于地球九百倍；大角；岁差运动；有着&猎户&腰带、六倍于太阳的&伐二&以及星云的猎户座，星云中能容纳我们的一百个太阳系；死去的和新生的星宿，例如一九0 一年的那颗&新星&我们的太阳系正朝着武仙座冲去；所谓恒星的视差或视差移动，也就是说，实际上恒星是在不断地从无限遥远的太古朝无限遥远的未来移动着。相形之下，人的寿命充其量才七十年，不过是无限短暂的一段插曲而已。

Namety, under the action of J2 perturbation, relative right ascending node, argument of perigee and mean anomaly of satellites formation will drift secularly.

首先，分析J2摄动对编队卫星相对轨道要素的影响，即J2摄动使相对升交点赤经、近地点辐角和平近点角产生长期漂移。

The configuration stability of the elliptical orbit satellite constellation requires the stabilization of the ascending node right ascension, the argument of perigee and the mean anomaly at the same time.

椭圆轨道星座构型稳定性要求同时实现升交点赤经、近地点幅角和平近点角的稳定。

Because of the secular perturbation variations of the ascending node right ascension, the argument of perigee and the mean angle caused by the initial deviations of the semi-major axis, the inclination and the eccentricity are linear time-variant, then the active biases of the semi-major axis, the inclination and the eccentricity can realized the self-stabilization design of the elliptical orbit satellite constellation, and so the configuration stability will be improved.

通过初始偏差对椭圆轨道卫星的长期影响分析可知，轨道半长轴、倾角和偏心率的初始偏差对升交点赤经、近地点幅角和平近点角的长期摄动变化是线性的，因此通过主动偏置轨道半长轴、偏心率和倾角能够实现椭圆轨道星座构型的自稳定设计，从而提高其构型稳定性。

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution.

结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。

The production moved off-Broadway to New York City, where she won the Joseph E. Calloway award for her performance, and was profiled in American Theater Magazine as one of ten young theater artists to watch.
