查询词典 diffuse and flat

Saddle shaped AMF can produce a radial expanding force, which has more effective effect on resisting the pinch effect of self-generated azimuthal magnetic field of arc current. This effect of saddle shaped AMF can keep vacuum arc in diffuse mode under much higher current. So the limiting current interruption capacity of vacuum interrupter can be enhanced.

为了进一步提高纵向磁场对真空电弧的控制作用，本文提出在真空灭弧室的触头间引入从触头中心向边缘逐渐增强的非均匀纵向磁场，马鞍形纵向磁场会对真空电弧产生一个径向扩张力，而纵向磁场分布的合理设计可以使这一扩张力进一步抑制真空电弧自生环向磁场对电弧的箍缩作用，从而使真空电弧在更大的电流时仍能保持在扩散态，使真空灭弧室的极限电流开断能力得以提高。

Soon after, various progressive environmental laws were enacted, including a groundbreaking legal recognition in 1985 of a civil public action to defend diffuse interests in environmental matters, locus standi being extended to the emerging NGOs .

不久之后，各种进步的环境法律的制定，包括1985年为维护公众被剥夺的环境权益的民事诉讼中所达成的开拓性法律共识，和形成的非政府组织也得到公认的正式地位。

Voyager 1 found that Enceladus orbited in the densest part of Saturn's diffuse E ring , indicating a possible association between the two, while Voyager 2 revealed that despite the moon's small size, it had a wide range of terrains ranging from old, heavily cratered surfaces to young, tectonically deformed terrain , with some regions with surface ages as young as 100 million years old.

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。

After he had slumber'd, rather than slept, about half an Hour, he wak'd again, and comes out of the Cave to me; for I had been milking my Goats, which I had in the Enclosure just by: When he espy'd me, he came running to me, laying himself down again upon the Ground, with all the possible Signs of an humble thankful Disposition, making a many antick Gestures show it: At last he lays his Head flat upon the Ground, close to my Foot, and sets my other Foot upon his Head, as he had done before; and after this, made all the Signs to me of Subjection, Servitude, and Submission imaginable, to let me know, how he would serve me as long as he liv'd; I understood him in many Things, and let him know, I was very well pleas'd with him; in a little Time I began to speak to him, and teach him to speak to me; and first, I made him know his Name should be Friday, which was the Day I sav'd his Life; I call'd him so for the Memory of the Time; I likewise taught him to say Master, and then let him know, that was to be my Name; I likewise taught him to say, YES, and No, and to know the Meaning of them; I gave him some Milk, in an earthen Pot, and let him see me Drink it before him, and sop my Bread in it; and I gave him a Cake of Bread, to do the like, which he quickly comply'd with, and made Signs that it was very good for him.

他的皮肤不怎么黑，略带棕色，然而不像巴西人或弗吉尼亚人或美洲其他土人的肤色那样黄金褐色的，令人生厌，而是一种深茶青色的，油光乌亮，令人爽心悦目，劫难以用言语形容。他的脸圆圆胖胖的，鼻子却很小，但又不像一般黑人的鼻子那样扁；他的嘴形长得也很好看，嘴唇薄薄的，牙齿又平又白，白得如同象牙。他并没有睡得死死的，实际上只打了半小时的盹就醒来了。他一醒来就跑到洞外来找我，因为当时我正在挤羊奶，我的羊圈就在附近。他一见到我，立刻向我奔来，爬在地上，做出各种各样的手势和古怪的姿势，表示他臣服感激之心。最后，他又把头放在地上，靠近我的脚边，然后又像上次那样，把我的另一只脚放到他的头上，这样做之后，又向我作出各种姿势，表示顺从降服，愿终身做我的奴隶，为我效劳。他的这些意思我都明白了。我告诉他，我对他非常满意。不久，我就开始和他谈话，并教他和我谈话。首先，我告诉他，他的名字叫"星期五"，这是我救他命的一天，这样取名是为了纪念这一天。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.
