查询词典 undulation

The results indicate that the formation of loess vertical joints can be divided into two phases:① the formation of inner fissure, i.e. in the beginning of deposition, the undulation of terrain leads to uneven distribution of loess, then when it rains uneven collapsibility generates, which leads to generate inner fissures ;② the stage of fissure extension, namely loess continues deposition after the inner fissures have been formed, the increasing of the top pressure makes the top of inner fissure lie in the state of tensile stress, so, when the stress reaches its tensile strength, the inner fissure extends along the vertical direction and then becomes a vertical joint.

结果表明黄土垂直节理的形成可分为 2 个阶段：①内裂隙形成阶段，开始沉积时，由于地形的起伏导致黄土厚度上的分布不均匀，在降雨时产生不均匀湿陷，从而导致产生内裂隙；②裂隙扩展阶段，内裂隙形成后黄土继续堆积，顶部压力的增长致使裂隙顶部土体受到拉应力作用，当达到其抗拉强度时裂隙就会沿竖直方向产生扩张而形成垂直节理。

In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。

The fish is propelled by undulation s of a long-based dorsal fin while the body axis is in many cases held straight in swimming.

以依靠长背鳍推进的&尼罗河魔鬼&为研究对象，对柔性长鳍波动推进模式的运动学进行了研究。

If the TBCs system is homogeneous, the TGO will take on relatively regular and periodical undulation. Unfortunately, in actual situation, some abnormal thick areas will be presented in TGO, which is in single-layer or multi-layer form. In SEM, it can be seen that such protrusion areas originate from TGO, and penetrate into bond coat layer gradually with the increment of oxidation time, namely, the oxidation localization phenomenon occurs.

如果体系均匀，则TGO层将表现出较规则的周期状起伏，但在实际服役过程中，TGO层经常出现单个的异常厚部位或多层的异常厚部位，在扫描电镜图上呈现出钉子状或瘤状的局部突起物，这种突起物源于氧化层，并随着高温工作时间的延长向粘结层中扩展，即发生了氧化局域化现象。

The results show that within the Philippine Sea and the South China Sea, short wavelength lineations of the geoid undulation are parallel or cross to magnetic lineations and rifting ridges.

After Huang Qu senior official yellow Jinlong looking pensive stopping, also in a low voice saying:"Knows, on the Earth 60,000,000 year ago dinosaur exterminate, it is said is because at that time a diameter reached 200 kilometers planetoids to hit Saturn high speed, caused the Saturn entire stratum and the earth's crust receives the undulation, and caused the fierce reverse volcanic eruption, finally acted according to the near several centuries the continually exploration research to indicate, Saturn periphery several satellites, and even the giant beautiful saturn's ring, possibly all was creates by this direct hit, moreover most surprising was, spouted the Saturn parent substance together after the burning hot Saturn lava material coagulation, formed the diameter reached 30 kilometer hit fragment, after is hit unexpectedly Saturn fierceSways the movement, flung the Saturn orbit rapidly ......"

黄区长官黄金龙若有所思的停了停之后，又低声的说道：&知道吗，地球上6000万年前的恐龙灭绝，据说就是由于当时一颗直径达200千米的小行星高速撞击土星，导致土星整个地层和地壳受到波动，并引起剧烈的反向火山喷发，结果根据近几个世纪的持续探索研究表明，土星外围的几个卫星，乃至巨大美丽的土星光环，可能都是由这次直接撞击造成的，而且最令人惊讶的是，一块喷出土星母体由炙热的土星熔岩物质凝固后，形成的直径达30公里的撞击碎块，竟被撞击后土星剧烈的摇晃运行，急速甩出了土星轨道……&

In Hogarth's view, the undulation line, and the snake line are both called beautiful lines, aspecially the snake line, it is beautiful, full of charm and attraction, third, revealing the characteristics of The Analysis of Beauty: one is from the nature, the other is the observation with the eyes, with the analytic method in form.
