大改变

The present digital water level recording may possibly lose some information,so large earthquake caused abnormal change of water level recorded by analog recording is clearer than that by.

认为：目前的水位模拟记录较数字化记录能更清晰地看到巨大地震引起的水位异常变化过程；大震引起的水位上升和下降可能是地震波的作用改变了构造单元的应力所致，并与井点的地质构造部位有关；同一井孔对同一断层上破裂方式一致的大地震的响应方式是一致的，只是对震级大的地震响应幅度大，震级减小，响应幅度亦减小

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。

First, we made a model of exhaustive exercise in rats, and used sucessfully the model in this study. We studied the effects of exhaustive exercise on adhesive behaviour of leukocytes in mesenteric venules by using an intravital microscope video system Its results indicated that the adhesiveness of circulating leukocytes to mesenteric venules enhanced after exhaustive exercise in rats.

首先，本文以游泳方法建立了大鼠模拟运动力竭模型，并成功地将此模型运用到本研究中；设计制作了肠系膜固定有机玻璃板，组成了一套活体显微观察实验系统；研究了大鼠运动力竭前后肠系膜微循环中白细胞粘附行为，结果表明：大鼠运动力竭后肠系膜微循环血流流态发生了明显的改变，大鼠运动力竭后肠系膜微循环中白细胞粘附性增强、白细胞滚动速率降低、在体白细胞变形性减小，将影响微循环正常的灌注，是导致微循环障碍发生发展的一个重要原因，进而最终表现为机体运动能力和运动质量下降。

A model of continuous beam with spring supports is put forward to analyse time-dependent structural systems.

针对施工期现浇钢筋混凝土结构的时变性，定义楼板刚度与模板支撑的刚度比为施工时变结构体系的弹性特征值，建立了以施工时变结构体系弹性特征值为参数的现浇钢筋混凝土结构施工受力性能分析的弹性支撑连续梁模型，基于该模型，分析了施工期现浇钢筋混凝土结构的受力特性，发现在特定施工方案下，当施工时变结构体系的弹性特征值较小时，最大施工荷载出现的楼层位置会提前，而拆模时间也会改变最大施工荷载出现楼层的位置；施工时变结构体系的弹性特征值和拆模时间都影响楼层承担的最大施工荷载比率(荷载比率定义为结构承担荷载与楼板自重的比值)；施工期楼层承担的最大施工荷载随楼层位置呈现波动特性，随楼层位置增高波幅逐渐减小，最后趋于稳定。

ResultsThere was no expression of Caspase-3 in group A. The expression of Caspase-3 in group C was decreased compared with that in group B（P＜0.01. In groups B and C, expansion and vacuolization of mitochondria, swollen neurons and apoptotic bodies appeared, which suggested that WBH could induce neuron injury, and the neuron injury in group C was more severe than that in group B.

结果A组大鼠海马区神经元无Caspase-3表达，B、C两组大鼠海马区神经元有Caspase-3表达，B组较C组Caspase-3表达平均灰度值减小。B、C两组大鼠海马神经元超微结构发生改变、细胞器水肿，部分线粒体空化，内质网稀疏，突触前膜、后膜结构不完整，可见自噬体结构；B组大鼠的神经元超微结构损害较C组轻。
