岁差

In addition to being a fun and intriguing gadget, the Powerball also is a great way to directly experience the Gyroscopic Effect (you know - angular momentum, linear momentum, centripetal force, precession and all those neat physics properties).

除了是一个有趣和迷人的小工具，威力也是一个好方法直接获得的经验的陀螺效应（你知道-角动量，动量，向心力，岁差和所有那些整齐的物理属性）。

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。

I want to live to be a hundred minus one day

那我就活一百岁差一天。

If you live to be a hundred,I want to live to be a hundred minus one day.

如果你要活上一百岁，那我就活一百岁差一天

Its values, determined from different kinds of observations and models are reviewed. Moreover, its relation to precession and its effect on nutation computation are discussed.

介绍了由不同的观测方法和模型给出的地球动力学扁率值，并讨论了它与岁差的关系和对章动计算的影响。

Under the effect of every order tidal moment, the expression of precession and nutation for the CIP axis is presented.

在各阶潮汐力矩的作用下，得到CIP轴岁差章动的表达式。

Due to lunar precession , this time is longer than that if the perigee's position was fixed.

由於月岁差的关系，这个时间比近地点不变的情况下所需之时间长。

This alignment occurs as a result of the precession of the equinoxes.

此路线的发生是由于分点岁差的结果的。

It is proved that the expression of precession is independent of Earth model.

同时还证明了岁差表达式与地球模型无关。

The so-called lunisolar precession is caused by the inequality of the moments of inertia of the earth.

所谓日月岁差，是由于地球转动惯量的不相等造成的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
