使波动

The analysis of the continuous property of raw silk size Setting the decaying rateλand the quasi-cycle value T in the model of the silk size autocorrelation coefficient, building the time series of a single cocoon reeling silk size with autoregressive model, then by combining k such time series according to different phrase, obtained time series of the raw silk size, and finally count up the silk size deviation of the time series.

利用一理想化的正弦波模型生成一粒缫生丝纤度时间序列，通过调查该模型中波动幅度及波动周期的变化对自相关系数序列衰减率的影响，初步建立起一粒缫生丝纤度自相关系数列衰减率λ与纤度时间序列特征数之间的关系式。从而使我们可以生成具有要求连续性特征的生丝纤度时间序列，为进一步研究生丝纤度连续性特征提供了新的途径。

The TCR firing angle can be fully changed within one cycle of the fundamental frequency, thus providing smooth and fast control of reactive power supply to the system.

即不管负载的无功功率如何变化，总要使二者之和为常数，这个常数等于电容器组发出的容性无功功率的数值，使取自电网的无功功率为常数或为0，即：=常数（或0），最终使得电网的功率因数保持在设定值，电压几乎不波动，从而达到无功补偿的目的，以抑制负载波动所造成的系统电压波动和闪变。

The theatrical foundation of this paper is option pricing model. This paper focuses on the Black-Scholes model, details the basic postulation, principle and pricing formula. And it is pointed out that the postulation that volatility is constant can't reflect the varying market volatility. Violation of this postulation will lead to biased pricing results.

期权定价模型是本文分析的理论基础，文中以Black-Scholes模型为主，分析了期权定价模型的基本假设、原理与定价公式，指出波动率为常数的假设不能反映市场波动率的变化状况，对该假设的违背将使定价结果产生偏差，因此，波动率在期权定价中有重要的作用。

Thirdly, they migrate to a certain direction. Asthenosphere movement leads to the movement of depression-uplift structure. Crustal surface shows undulatory movement due to the asthenosphere. Deformation and movement law of depression-uplift structure accordingly develops.

坳陷构造运动的动力是软流圈运动的结果，软流圈作波动运动使地壳表层也作波动运动，并形成相应的坳隆构造变形和运动规律。

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。

In this work the unhomogeneity of microstructure in product strips has been studied, and the methods to control grain size with the hot rolling technological parameters are given. The capacity to control the property unhomogeneity of hot strips has been greatly improved after using the methods. According the statistics of production, the the property unhomogeneity over 99% strips is less than 80 MPa in a batch of coils, and less than 40MPa in a coil.

8对大量实际生产带钢组织和性能的不均匀性进行了研究，提出了通过调整热轧工艺参数来进行晶粒尺寸均匀度控制的的具体措施，实际生产采取该控制手段后，使宝钢对管线钢性能波动的控制水平得到大幅度的提高；强度波动由管线钢生产初期的批量内150～200MPa，卷内100MPa提高到批量内00MPa，卷内0MPa，可按合同交货；大生产实际水平为：99％产品的强度波动量达到批量内0MPa，卷内0MPa。

In the process of impact of abrasive jet on rock, resulting dynamic stress plays an important role in rock destruction. The stress wave resulted makes local rock tensile and shearing, then makes rock destructed. In the conditions of some hypotheses, the mechanical model that rock is applied by stress wave, i.e. jet wave basic equations, are set up by wave theory, and the formula of the maximum normal stress resulted by stress wave is deduced according to known boundary conditions.

描述了岩石材料在磨料射流的冲击下破坏的主要原因，分析了应力波就是岩石局部受到拉伸和剪切并最终使岩石发生破坏的根本因素，在这一假设的前提下采用波动理论建立了岩石受应力波作用的力学模型即射流波动的基本方程，在已知的边界条件下推导出了由波动引起的最大正应力的计算公式。
