向地的

Paul, in his turn, communicates to Christians their true apostolate: to reveal to every person, without discrimination, that God is close to them and loves them infinitely.

保禄在皈依后，向我们基督徒述说何谓真正的宗徒事业：就是不带歧视地向所有的人宣示，天主就在我们身边，他无限量地爱着我们。

The effect of tribology factors on bearing vibration is studied experimentally. AR model and WPT are used to processing the normal arid abnormal signals. The results are as follows:1. The vibration of ball bearings is caused by the tribology action of contact pairs of ball and ring races and has the essential of tribo-dynamics. Any factors affecting the tribology characteristics of contact pairs will affect vibration and noise of bearings consequently.2. Vibration characteristics of bearing keep almostly unchanged with the increasing of axial load expecting the increasing of nature frequencies. When radial load increasing with axial load unchanged, nature frequencies keep unchanged but some new vibration peaks appears in the spectrum.3. Vibration amplitudes are damped and nature frequency are enhanced with sufficient lubrication. Vibration and noise of bearings increase obviously and roar can happen and the contact surfaces scratch slightly under insufficient and unclean lubrication state. Bearing will be disabled in a few minutes without any lubrication.4. Bearing vibration is unstable under low speed. With the speed increasing, the vibration become stable and natural frequencies increase slightly but the amplitudes increase apparently.5. Bearing vibration can be excited only by some harmonics ofwaviness without lubrication and by all harmonics with lubrication based on the theoretical analysis.6. The nature frequencies of ball bearings decrease with the increasing sizes. When international clearance increasing, nature frequencies decrease in radial and increase in axial and angular and the amplitudes increase in radial and decrease in axial and angular. When the number of balls increasing, nature frequencies increase and amplitudes decrease. When the pitch diameter increasing, axial nature frequency increase and others nearly keep no change. When outer race groove curvature radius increasing, nature frequencies increase in radial and decrease in axial and angular and amplitudes keep no change in radial and increase in axial and angular. When inner race groove curvature radius increasing, nature frequencies decrease and amplitudes increase.7. The distortion in amplitude and frequency components of bearing vibration signals picked up by the present probe measurement method is founded and right conclusions cannot be achieved by the signals. When accelerometer is rigidly screwed with steel stud onto a flat outer surface of a ball bearing, vibration signal can be got without distortion and the reliability of research on bearing vibration is assured.8. AR model is suitable for large samples of bearing vibration signals, square root of length of samples can be used as the upper limitation of order determination and the FPE order selection criterion is effective. Many advantages of AR spectrum are founded over the classical based on FFT.9. Time-Frequency analysis is necessary for abnormal noise of ball bearings. WPT overcomes the principle shortcomings of STFT and proved to be a best tool to process the abnormal signals.

理论分析和试验研究表明： 1球轴承振动是钢球—滚道接触副中的各种摩擦学作用引起的，具有摩擦动力学的本质，任何对接触副的摩擦学特性有影响的因素都将对球轴承的振动和噪声特性产生影响； 2中心轴向载荷作用下，载荷增大使球轴承的固有振动频率升高，载荷越大同样的载荷增幅引起的频率升幅减小，足够大的中心轴向载荷作用下载荷的变化对球轴承振动的频率特性不会产生明显的影响； 3轴向和径向联合载荷作用下，径向载荷不大时球轴承振动的固有频率基本不变，但是可能引起变刚度激励的非线性振动，出现新的频峰，过大的径向载荷将使部分钢球脱离接触，使球轴承的振动和噪声呈现不稳定状态； 4润滑对球轴承的振动和噪声特性有重要的影响，良好的润滑对振动有明显的抑制作用，润滑不充分时，振动和噪声的水平会有明显增高，一定条件下还会激发接触副中的谐振，发出啸声，造成接触表面的伤害，无润滑干接触时，短时的运转就会损伤接触副表面，使振动和噪声迅速增大，并随时可能引发严重的磨损和卡滞失效；接触副润滑良好时，油膜的"刚化效应"使球轴承振动的固有频率有所提高，润滑剂中含有弥散性污浊时，振动的幅度总体升高，但弥散性污浊不会改变球轴承振动的频率特性；浙江大学博士学位论文：球轴承振动的研究 5低速时，球轴承振动的基本特征呈现不稳定状态，随着转速的提高，球轴承振动的频率特性趋于稳定，固有频率频峰升高； 6理论分析表明，干接触时钢球和滚道表面波纹度的某些谐波分量能激励球轴承的振动，振动的幅值与谐波幅值成正比，实际球轴承中钢球的分布不可能完全均匀，波纹度的激励作用会随时发生；润滑接触的分析表明，波纹度的任意谐波分量均能激励球轴承的振动； 7球轴承的几何和结构参数分析表明，球轴承尺寸越大，径向、轴向和角振动的固有频率越低；钢球中心圆直径增大，球轴承的径向和轴向振动的固有频率基本不变，角振动的固有频率有所上升，振动的幅频特性基本不变；径向游隙加大使球轴承的径向振动固有频率降低，轴向和角振动的固有频率有所升高，径向振动幅频特性的幅值升高，而轴向和角向降低；钢球的数量增多使球轴承振动的固有频率上升，幅频特性的幅值下降，径向振动的幅值下降最为明显；外圈沟曲率半径系数增大使球轴承径向振动的固有频率升高，轴向和角振动的固有频率降低，径向幅频特性基本不变，轴向和角向幅频特性幅值升高；内圈沟曲率半径系数增大使径向、轴向和角振动固有频率均下降，振动幅频特性的幅值均有升高； 8试验对比表明，传感器采用探针式安装时，由于探针接触副接触特性的影响，钡(量得到的球轴承振动信号有失真，采用专门设计和制作的试验球轴承，以固定式安装加速度计，首次测量得到了球轴承振动的真实信号，通过对振动信号的分析，验证了球轴承振动的理论模型； 9)基于时间序列分析的AR模型适用于大样本球轴承振动信号的分析，以样本长度的均方根值作定阶上界，FPE做判阶准则，给出的AR谱光滑，频率分辨率高，是球轴承振动分析的简便而可靠的手段； 10以时频域分析的小波包变换分析球轴承异音信号能够比较好地定位和聚焦异音发生的时间，时间间隔，频率范围，同样是球轴承振动分析的可靠的手段，可用作球轴承故障诊断技术。

There are also closed centers embedded on the belt, appearing zonal non-uniformity. The classic method of zonal deviation can just depict the zonal non-uniformity of subtropical high partly, while meridional deviation from the zonal mean along the equator can describe both the belt and the centers on it, i.

用传统的纬向偏差仅仅能部分地描述副高的纬向不均匀；而用新引进的相对于赤道的纬向平均的经向偏差可以同时描述副高带及其上单体的经向和纬向不均匀。

Medium 的含义是"介质",没有这种"介质"便达不到一定的目的 It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help itspassage even when the wind is adverse.

它不知疲劳，也不夸耀自己的飞翔能力，然而它在空中十分自如，可以一直飞行6，000英里。飞向北方的筑有鸟巢的家乡以及从那里飞走，在飞行的过程中还要喂养已出窠的雏燕，甚至在顶风的时候也能够不费劲地穿过那似乎有助它迁栖的气流。

Arethusa was once a fairy maiden huntress.she carriedbow and arrows for artemis in her hunting.she was sodevoted to her work that she cared for neither admirationnor love.one sunny summer day,she felt hot and found a coolstream quite attractive.she jumped into the delightful streamand happily started swimming.presently she heard a bubbling in the stream and was surprised to find it was the thunderingvoice of the rivergod alpheus.the maiden made for the shore and,fully naked,started running away.taking a human form,the river-god followed closely in pursuit .onward they spedover hill and valley,across dark heights and over broad plains,until the waters of the western sea lay stretched out right before them .helplessly the exhausted arethusa cried to her patronessfor help.artemis instantly cast a cloud over her body,but the pigheaded alpheus was not to be tricked.then a cold sweatbroke from the maiden''s arms and legs.the drops of water fellfrom all over her body.she had been turned into a spring!

阿瑞塞莎是位迷人的仙女猎人。每逢阿耳特弥斯打猎时，她负责携带弓箭。她对工作专心致志，既不考虑赞美也不顾及爱情。一个炎热的夏日，她感到很热，便找到一条凉爽的溪流，深感惬意。她跳入令人愉快的溪水中，兴致勃勃地畅游。不一会儿，听到水泡声，她大吃一惊地发现：那是河神发出的闷雷声。仙女向岸边游去，赤身裸体地跑开了。河神便装成凡人的样子在后紧紧地追赶着。他们一直向前飞奔，越过小山，跨过峡谷，翻越大山，掠过广阔的平原，直到西海的水域展现在他们的眼前。绝望中精疲力竭的阿瑞塞莎哭叫着向她的保护神求救。阿耳特弥斯迅速将一层云雾披在仙女的身上。但顽固不化的阿耳法斯并未上当受骗。接着一股冷汗从仙女的肢体上溢出，并且浑身上下淌着水珠，她被变成一眼泉水了。

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地眼振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下：水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石，本文报告3例以快速转头治疗逆地眼振型水平半规管良性阵发位置性眩晕成功的病例，显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果，对於逆地眼振型水平半规管良性阵发位置性眩晕的治疗，作者建议先以快速转头作治疗性诊断，若病人马上复原，诊断为囊侧的顶帽沉石；若眼振转为向地型，则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石，进一步再以向地型的耳石复位法治疗病人。

She burned for two hours without changing, without swaying or kneeling-only glowing within, like a boiling fire glimpsed through silhouetted walls, like a hollow saint, like a flame-faced virgin gone to God, while I read by her light, kindled while Rimbaud in Paris burnt out his brain in a thousand poems, while night pooled wetly at my feet.

她毫无变化地烧了两个小时，没有剧烈晃动过或者低头闷烧，像个沸腾的火焰向墙的轮廓短暂地闪光，像个空洞的圣徒，或者像个有火焰般的脸孔的处子飞向神。我借着她的光读着里姆保，她烧着的时候里姆保在巴黎殚精竭虑地写了一千多首诗，夜晚的聚集的湿气湿了我的脚。
