自转

According to the analysis of the relation of between angle momentum and magneticmomentum, we find that a2 dynamo is main mechanism for the stars withdeep interior convection zone similarly late-M type stars.

从M型主序星的自转周期的和恒星内部对流区随色指数的分布来看，M型主序星的色球活动行为与αΩ发电机理论的预期有明显的差异。

The earth rotates in counterclockwise direction or from west to east.

地球按照逆时针方向或者由西向东自转。

The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second

整个蟹状星云跨越约10光年，在其正中心存在一脉冲星---有太阳一样的质量但体积只有小镇大小的中子星，蟹状星云脉冲星的自转速度约为30圈每秒。

2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.

深入剖析：地球可以说是一个非常奇妙的热核反应堆，当地球内部的压力达到一定的临界，地球物质中可衰变的核物质统称为热核物质，就会发生热核反应，从而产生巨大的能量，进而融化部分物质，形成岩浆即液态物质，这个反应层面可能是多个层面，第一层可能位于地壳与地幔之间，向上下两边对流，表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象；第二层可能位于下地幔与地核之间，压力更为强大，引起不易发生热核反应的热核物质发生反应，形成相对比较稳定的液化物质层，同时向上下两边对流，形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象；这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

根据访问期间对比利时皇家天文台在地球物理方面所开展的研究工作的了解及比方提供的材料，本文介绍了比利时皇家天文台在地球固体潮和重力测量方面的工作，在时间确定、地球自转的观测与研究和空间大地测量方面的活动，以及在地震学方面的工作，最后还简要地介绍了卢森堡大公国瓦尔弗当日地球动力学地下实验室的情况。

With Jupiter different, the air is the equatorial east blow, and the rotation direction of the same.

与木星不同，赤道的气流是向东吹动的，与自转方向相同。

5First direction with said motor and rotated in a second direction independently of said motor and gear train; anda governor for inhibiting rotation of said spool gear when it is independent of said motor and gear train, said governor including a governor gear mounted on said frame independently of said motor and gear train, said governor gear being meshed with said spool gear to rotate in unison therewith, and said governor gear 6 including means for inhibiting its rate of rotation in the form of a spring for fractionally engaging said governor gear with a friction surface.

This is by far the most serious and immediate problem now facing mankind, declared geophysicist Joseph Jankowski, who first observed the phenomenon.

这种自转减慢会不断导致更长的白天和夜晚，还会引起灾难性洪水到地震，再到大规模饥荒等一切灾难。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
