波动说

For improving the accurateness of theoretic analysis, a space variable method based on wave optics is presented.

为了提高理论分析的准确性，提出一种建立在波动光学基础上的空间变分析法，详细说明了形成新月形的空间变过程，并用计算机模拟出不同屈光度的近视眼瞳孔像及其沿子午方向的光强分布。

The wave has consciousness. As I mentioned before, when it realizes that it is being observed and measured, it will agglomerate as an object.

但是这个波动它有一个自觉性，我刚才说了，当它觉察到自己被观察、被测定的时候，会凝聚起来。

"If you define risk as volatility," which is what most analysts do, Mr. Glassman says,"history has shown that stocks are no more volatile than bonds" over the long term.

"如果你界定的风险波动"，这是什麼大多数分析家这样做，先生格拉斯曼说："历史已经表明，股市没有更多的波动大於债券"的长远目标。

Direct measurements splendidly confirm these predictions, and thus also the wave theory of light.

直接测量的结果圆满地确认了这些预言，因而也确认了光的波动说。

And it's just this hand which brings one country into the status of unsafety. No other than government can unify the interest of nation, government and people, can balance the long-term economic profit and short-term economic profit.

甚至可以说，正是这只"看不见的手"才使经济发展波动幅度变大，波动频率变高，正是这只手将国家经济带入了一种不安全的状态。

What does it mean in the wave theory?

在波动说中它的意义是怎样的呢？

Independent toxicologists contacted by New Scientist said Séralini's analysis overplays the importance of minor variations that most experienced toxicologists would consider to be random background noise.

新科学家》（New Scienctist，此文发表刊物）联系的独立毒理学家也说，Séralini的分析过分夸大了统计数据里的微小波动，对大多数有经验的毒理学家而言，这类波动只能算背景噪声。

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。

针对随机波动率模型下美式期权定价的复杂性，本文在已有的欧式期权定价公式下，利用二叉树与随机波动率矩阵的结合，当股票价格收益波动率服从马尔可夫随机过程时，实际波动率σ下美式期权价格是随机状态波动率下价格的加权和，其权重可以由波动率矩阵算出，并且给出了对应思想的算法，最后通过数值算例进一步说明了算法的有效性。

Maybe we need a "wave theory" of cultural exchange, to explain the constant oscillation between East and West.

也许我们需要用文化交流的&波动说&来解释东西之间持续的摇摆。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
