波动的

Base on the China's limit order-driven electronic trading system,such factors as the stock price,the depth of market,the probability of informed trading, the fluctuation of stock price,the impact of information and the imbalance of orders will all affect the implicit transaction cost.

4指令驱动制度下的股票市场，隐形交易成本和股价、市场深度、知情交易概率、股价波动、信息冲击与买卖指令的不平衡性密切相关，理论和实证表明：市场深度越大、知情交易概率越小、股价波动越小、信息对股价的冲击越小以及买卖指令的不平衡性程度越低，隐性交易成本就越小。

While the new components having the same numbers with these original physical vectors are introduced and the new components are combined with those original physical components to form a new symplectic space, the ray problem of wave propagation in geometrical optics is converted into the problem of Lagrange submanifold in the symplectic space.

本论文的工作作为国家自然科学基金地震波传播与成像项目（NO.40174032）的一部分，得到如下结果：论文分析了利用Maslov方法求解非均匀介质中波动方程高频近似解的基本原理和求解过程，构造了介质系数只在一个方向变化时波动方程高频近似解的通用计算公式。

The paper employs the CF band pass filter to measure the cross-correlation coefficient and the leading / lagging relationship between credit variables and the economic growth rate. The result shows that the cyclical fluctuation of medium- and long-term loans and construction loans is in advance of the economic growth, and the cyclical fluctuation of industrial loans and commercial loans is relatively consistent with that of the economic growth.

运用CF带通滤波测算信贷变量与经济增长率之间的交叉相关系数和先行/滞后关系，得到的结论是：中长期贷款和建筑贷款的周期性波动提前于经济增长，工业贷款和商业贷款的周期性波动与经济增长率相对一致。

We use the data from BHP company in 1995-2001 and calculate the implied volatility. By comparing the implied volatility calculated from actual option price and the assumed volatility in the model, it is found that Black-Scholes Model does underprice the Out-of-The-Money options and overprice the In-The-Money options because of the wrong assumption on the volatility.

本文选择了澳大利亚BHP公司1995年-2001年其中五年的数据，从实际期权价格中计算得到隐含波动率，并把其与Black-Scholes模型中的假设波动率进行比较，最后可以发现，Black-Scholes模型低估了虚值期权的价格，高估了实值期权的价格，与一般的研究结果恰好相反。

As a result, this paper gets some important findings just as follows: Firstly, the participancy of institutional investors has great effect on the co-movement of stock prices.

本文得到如下重要研究结果：第一，机构投资者的参与程度对股价波动同步性具有显著的影响作用，中国证券市场以个体投资者为主体的结构是较高股价波动同步性的原因之一。

This research hope uses the information of "bond yield spread" and "the market value of equity" which is available in the market to do the calibration by "Nelder-Mead Simplex Method" numerical method, and obtain the theoretical default probabilities which calculates in the most suitable property market value and the volatility of property market value.

由於资产市值与资产市值波动度的难以评估，所以无法以正向带入变数预测公司违约机率，本研究主要希望利用市场上所能获得的资讯『公司债殖利率差』、『股东权益市值』对模型以Nelder-Mead Simplex Method的数值方法做回推求得在最适资产市值与资产市值波动组合下计算出的理论违约机率。

This will increase the frequency of the inverter. The output of the hysteresis band is changed to be anisomerous and some available results are given by emulating.

本文在分析这种波动产生原因的基础上，提出对滞环比较器进行不对称上下限的设置以抑制转矩较大的波动和降低逆变器的开关频率。

In order to adapt the rural electricity system which has the character load fluctuate frequentand the range of fluctuate is large, this paper apply instantaneous reactive power theory to detectreactive current of the system, this method enhance the speed of detection, at the same time, it canassure the detection precision when the load of rural electricity system is dissymmetric.

为了适应农电系统负荷波动频繁且波动范围大的特点，本文应用瞬时无功功率理论检测系统的无功电流，这种检测方法即提高了检测的速度，同时在农电系统负荷不对称的情况下也能保证检测精度。

A large space of the dissertation is devoted to a thorough exploration and interpretation of the complicated variation of Yeats'passion to Gonne, which correspondingly arouses changes in poetic style of his lyrics to Gonne.

结合文体学与诗歌研究的方法，文章首先深入阐释了叶芝对Gonne 感情复杂的波动，这种波动在叶芝写给Gonne 各阶段的诗中有明显风格变异的体现。

It provides the link between the theoretical background for limiting the voltage stress on each switching component and the range of voltage variation for an imbricated cell of flying-capacitor multilevel inverter.

并根据单元电压的波动特性，给出了悬浮电容容量的具体选择方法，为保证功率开关承受均衡的阻断电压和有效限制单元电压的波动范围提供了理论依据。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
