比如获得地区预选优胜后，老头子笑话他包扎眼伤的纱布上写的字迹（如果是平时越前早就冒十字路口了）但此时他只是淡淡解释那是为了纪念青学夺冠，嘴角甚至是带着若有若无的弧度；又比如当MOMO失去正选资格后没来上课，面对其他人的询问他闭着眼丢下口头禅走人，但在天台上睡午觉时看到MOMO打完水漂大笑着离开，他又不禁莞尔，似乎是终于放下了心中的一块大石；再比如关东大赛第三单打时，乾为了救球摔坏了眼镜，当他重新戴上备用镜时看见青学全体对他微笑着竖起大拇指——如果你够细致的话会发现：眼神无奈的越前的"V"手势是被菊丸弄出来的，但另一只手上竖起的大拇指绝对没有受到他人的牵制，换言之，那是越前自愿的、真心的加油……诸如此类，不胜枚举。

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.

As the density of Al and Cu was quite difference,it was apt to delaminate and restrain the process of alloy by wet milling.The case was improved when dry milling,though it would be some reunite with the time of ball-milling prolonging.(2)The best technique parameters of high energy ball milling to prepare metastable powders of Cu-Al alloy were;the addition of Al powders was 1% in quality,the powders of Cu-Al were completely alloyed after high energy ball milling for 20 h.

1提出采用高能球磨制备Cu-Al合金粉的有效方法，认为由于Cu和Al的密度相差比较大，采用以液态酒精为过程控制剂的湿磨时，容易发生分层，抑制了合金化，采用干磨时，以硬脂酸为过程控制剂，虽然随球磨时间的延长会发生轻微的团聚，但能达到良好的合金化效果。

The speed of the ball early solid shot hurled from the last ball the distance and time to decide, the greater the force distance, the shorter the time, the solid shot the ball the greater the initial velocity, initial velocity of shots depends on the ability of students ...

实心球出手初速度主要是由最后用力投掷球的距离和时间决定，用力距离越大，时间越短，则实心球的出手初速度就越大，出手初速度的能力主要取决于学生的

The Jazz missed again at the other end, but the Lakers bobbled the ball, too, and Williams crashed to the floor for a loose ball and forced a jump ball. The guard didn't stand a chance against Lakers center Pau Gasol, but it ate up time and the Lakers turned it over again.

爵士进攻再次未果，但是湖人也没能控制好皮球，德隆的一次倒地抢球帮助爵士获得一次跳球机会，当然这个190cm的小个后卫在跳球方面肯定不是加索尔的对手，但是它消耗了湖人的进攻时间而且湖人再次出现失误。

使用方法：1、操作就像平时洗发一样简单，戴上手套双手把头发润湿（不管白发、脏发、油污发）。2、用毛巾把水擦净，把本品按1：1比例倒入手上稍加搅拌，长发白发要多用，短发可少些，（初次使用以平时洗发的两倍左右）。3、放在头发上反复揉搓，必须让洗发露沾到每根头发的根部，揉搓可快可慢，累了可稍加休息，总之不停的在头发上前后左右揉搓，特别是根部，坚持7-10分钟的揉搓可冲洗，见到的是一头乌黑亮丽的黑发。4、本品为营养性促黑养发产品，必须要连续使用3次或以上。

As the ball struck the bottom of the post and inched over the line it was clear to me just how far the game had come; in FIFA 08 the ball would have gone out of play because Kuyt wouldn't have kept it in, a defender would have pushed Kuyt over by the time he was just shaping up for the cross, and Gerrard would have chested the ball straight into the goalkeeper's grasp rather than headed it.

当小球击中的底部后，并小幅的路线很清楚我领悟到，比赛已经到来，在国际足联08球会已经发挥了，因为库伊特不会一直在，一个后卫将推动由库伊特的时候，他刚刚形成的交叉，并且将杰拉德胸部球直接进入守门员的把握，而不是领导它。

The same name as on the 1st fairway wood and the ball, the mixed rod also stressed the effects of Face-Centered, that is, the head of the center of gravity location and the most central of the sweet spot even as first-line in order to form a ball the best effect, At the same time expanding the sweet spot hit, in addition to showing stability ball is more, it can play the advantages of the distance.

就像同名的一号木杆和球道木一样，混血杆也强调Face-Centered的效果，亦即把杆头的重心位置与最中央的甜蜜点连成一线，以便形成最佳的击球效果，同时扩大击球甜蜜区，除了展现击球稳定度之外，更可发挥距离的优势。

Use of this tactic in the opponent's first attack, there is no fully effective, and the ball when the ball is not dead, the other side of the ball off you, this time on the effectiveness of this tactic, and then you need to do is have the potential of the fast ball to your teammates are back on the OK!!

运用这个战术是在对手的一次进攻，并没有完全奏效，并且球没有死球的时候，对方的球被你断了，这个时候这个战术就奏效了，这时你需要做的就是又快有准的把球传给你正在进行反击的队友就OK了！！
