The authors find coupling mechanism of momentum of nutations between solar and earth. It is caused by solar radiation, earth's rotation and revolution, angle between ecliptic and equator, irregularity of oceans and continents between northen hemisphere and southen hemisphere and layer structure of earth's core.

作者发现：太阳辐射，地球自转与公转，黄、赤交角的存在，陆地和海洋在地球表面南、北半球的不规则、不对称地理分布，及地球内部因〖ZZ〗形成的分层结构，构成了一套天然的能使地球产生自由章动的日、地间动量相耦合的物理机制。

The multi-gear pump ultimately solves some important problems such as unbalanced radial force and high flow pulsation of the common gear pump.

Technological director Wang Jiang had made an analogy vividly and popularly that game procedure's writing is frame of game,just like the human skeleton; story plot and characters' planning like the muscles of the human body, can let people move; The fine arts picture of the game is the human skin, and can make people more plump and more beautiful.

技术总监汪疆形象通俗地打了个比方：&游戏程序的编写就像人体骨架，是游戏的框架；剧情故事、人物的策划好似人体的肌肉，能够让人动起来；游戏的美术画面就是人体皮肤，可以让人更加丰满漂亮。&

With colorful plumage and wing s that flap when it talks and with the capability of repeating whatever is said to it in brief intervals of seconds, by way of an electronic microphone pick-up, record and playback function

此种鹦鹉通过一个电子麦克风而具备接收、录音和重新播放功能，在几秒内能重复对它所说的话，在说话时它彩色的羽毛和翅膀会不停地拍动。

When we hear the confessions of young believers and the testimonies of well-instructed saints, we are made so happy that we must praise the LORD, and then it seems as if rocks and hills and woods and fields echo our joy-notes and turn the world into an orchestra.

当我们听到慕道友的忏悔告白，或是圣者感人的见证，就快乐地赞美主，而山川草木似乎也应和著我们雀跃的心情，踊动欢唱，编织出一首交响乐。

Initially, assuming that the contact between cam and tappet is"dry contart", a dynamics model of Hertzin contact stiffness and impact damping is established. Next, with dynamic load on cam—tappet pair from the model, an analysis is made both to unsteady EHD oil film in cam—tappet pair under condition of full and partial lubrtication and to wear characteristics of cam profile. then, according to the fact that the lubrication in cam—tappet contact surface is EHD lubrication, taking the interaction between stiffness and damping of unsteady EHD oil film and rigidity of solid object contact into account, a dynamics equation of valve train relating to the dynamic effect of EHD oil film is built up and solved. Consequently, a further study is made on the dynamic characteristics of valve train under interaction of EHD oil film dynamic behavior and the problem of EHD lubrication in cam—tappet pair. Finally, the dynamic effect of full and partial EHD oil film is studied accordingly.

首先，通过对凸轮—挺杆接触为&干接触&的假设，建立了考虑赫兹&接触刚度&和冲击&阻尼&的配气机构动力学模型，用由此求得的凸轮—挺杆表面动载荷对凸轮—挺杆进行了全膜状态和部分膜状态非稳态弹流润滑分析，并研究了凸轮轮廓的磨损规律；然后，是在凸轮挺杆表面存在弹流动压油膜这一事实的基础上，相当于在动力学方程中考虑非稳态弹流油膜的&刚度&、&阻尼&和固体接触&刚度&的耦合作用，建立并求解了考虑弹流润滑行为动力学效应的配气机构的动力学方程，从而深入地研究了弹流润滑行为与动力学行为耦合作用下的配气机构动力学特征以及凸轮挺杆弹流润滑问题；作为前面工作的对应部分，考虑弹流油膜动力学效应的研究工作也同样分为全膜状态和部分膜状态进行。

The comic effort with which he strove to make his tongue work made Princess Marya drop her eyes, and she had much ado to stifle the sobs that rose in her throat.

他仰卧着，背靠得很高，他那双瘦小的、青筋虬结的手平放在被子上面，他的左眼直瞪瞪地盯着，他的右眼歪斜，眉毛和嘴唇一动也不动。

I ailing tremendous pain, forced to swing his legs, arm and leg with a paddling, sweat soaked my clothes.

我忍着无比的疼痛，双腿用力地摆动，胳膊配合着腿划动，汗水浸湿了我的衣服。

He was in his alleys from the break of day, in summer, planting, cutting, hoeing, watering, walking amid his flowers with an air of kindness, sadness, and sweetness, sometimes standing motionless and thoughtful for hours, listening to the song of a bird in the trees, the babble of a child in a house, or with his eyes fixed on a drop of dew at the tip of a spear of grass, of which the sun made a carbuncle.

夏季天刚亮，他已到了畦埂上，插着，修着，薅着，浇着，带着慈祥、抑郁、和蔼的神气，在他的那些花中间来往奔忙，有时又停下不动，若有所思地捱上几个钟头，听着树上一只小鸟的歌唱或别人家里一个小孩的咿呀，或呆望着草尖上一滴被日光照得象钻石一样的露珠。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
