波动的

When investors are in the treasury secondary market, they have to undertake two kinds of risks: the first one is yield risk, that is, return of investment is lower than inflation rate. This risk can be depicted as the deviation between the ROI and the inflation rate. Secondly, fluctuation risk in the treasury secondary market, that is, the uncertain fluctuation risk may be bullish or bearish in the treasury market.This risk can be depicted as the square deviation of the treasury price in the secondary market.

在国债现货二级市场上的投资者，要承担的风险主要有两种：第一种风险是收益率风险，也就是投资收益率可能低于通货膨胀率的风险，这种风险可以用与通货膨胀率相比较的差值的大小来描述；第二种风险是二级市场价格波动性风险，也就是市场价格上、下波动的不确定性风险，这种风险可以用二级市场价格的标准差来描述。

And when the numbers of rational and irrational investors are almost equal, the effect of volatility on expected returns is weak.4. having extended a Bivariate Mixture Distribution model.

研究结果显示，在中国股市中，1997年之前，相同强度的冲击，收益为正的冲击与交易量放量的冲击对波动的冲击分别大于收益为负的冲击和交易量缩量的冲击；而1997年后情况则相反。

His Age of Diminished Expectations and Peddling Prosperity filled the gap between the boringly descriptive genre of "up-and-downeconomics" books and sensationalist and shallow "airporteconomics" books.

他写的《期望灭失时代》与微弱繁荣的时代，填补了枯燥乏味地描述经济波动的经济学书籍，与标题党式的、浅陋的、在机场出售的经济学书籍之间的鸿沟。

In this thesis, we theoretically analyze the fundamental reasons of profitability of technical analysis, stating the time-varying characteristic of expected return series and predictability from historical returns and other factors.

本文从理论角度分析了技术分析有效性的基础，从历史收益率等角度出发阐述了收益率的时变性特征，结合收益率波动的记忆效应，为技术分析的核心前提假设即价格趋势的存在提供了国内外研究的实证支持。

Using the climatologically mean temperature and salinity from the Levitus data, the solutions with different modes of the gravity waves and planetary waves are analyzed.

利用Levitus气候平均温盐资料，分析了线性理论意义下南海的重力波及行星波的不同模态解，其一阶模的相速度分布与真实地形关系十分密切；通过行星波的临界频率的计算，从理论上描述了南海行星波动的特征。

Our analysis result shows: in the judgment and decision-making process, the investor cognation biases can be divided into the cognation bias of price fluctuation, the estimate bias of corporate value, the manager bias of risk and wins, the manipulate bias of trading.

本文认为金融市场上投资者所具有的典型性认知偏差包括对股价波动的认知偏差、对上市公司价值的估计偏差、对风险和回报的管理偏差以及股票交易中的操作偏差四种；而深入分析投资者的这些认知偏差很有理论和现实意义。

Although the current price index system composed of representative indices such as consumer price index, retail price index and producer price index can reflect the inflation level with approximate accuracy, there still exist deficiencies such as inability to precisely reflect the purchasing power of consumers, inaccuracy and incomparability of price indices, easily affected by short-term volatilities thus misleading monetary policy.

尽管我国现行的以居民消费价格指数、商品零售价格指数、工业品出厂价格指数为代表的物价指数体系基本准确地度量了我国的通货膨胀水平，但也存在容易受短期波动的影响从而误导货币政策取向、不能有效反映消费者购买力的变化、价格指数的准确性和可比性不高等一系列缺陷。

In this state, theorists postulate, the liquid is made up of a continuously fluctuating mix of tetrahedral and more disordered structures, with the ratio of the two depending on temperature – just as Nilsson and his colleagues have found to be the case with water at the ambient temperatures important for life.

在这种状态下，理论家假设，这种液体是由一个不断波动的混合四面体和更加无序的结构构成的。两个比例主要取决于温度，-正如尼尔森和他的同事们发现，水的周围介质温度对生活的重要性。

Through the past six years they've been the most maniacal spending machines the world has ever seen. Stock market wobbles, rising interest rates, staggering personal debt, war, floods, hurricanes - nothing could slow them down. That was mainly because the value of their largest asset, housing, kept going up, and because they were confident about their jobs.

过去六年时间里，他们是全球最大的烧钱机器，即使股票市场振荡不止、不断升息、波动的个人债务市场、战争、洪水、台风的发生都无法让他们减慢花钱的速度，最主要是因为美国人家庭资产殷实、住房供给充足，而且他们对自己的工作充满信心。

A simulation research is conducted on the example of six-phase double star winding shifted by 30°synchronous motor.In order to investigate the control algorithm of multilevel inverter , high harmonics as well as its problems, a mathematical model of the control algorithm based on the voltage space vector is built. For the first time, the principle along boundary is introduced to confirm the chosen switch state when many switch states are corresponding to the same vector. Simulation analysis and hardware realization are conducted with the combination of diode clamped three-level inverter and five-level inverter.

建立了基于空间电压矢量控制算法的仿真模型；仿真研究中采用对偶小矢量搭配改善中点电位波动的问题；针对多个开关状态对应同一待选矢量的问题引入&循边原则&确定被选择的开关状态；对过调制问题进行了相应的处理：结合二极管嵌位式三电平逆变器和五电平逆变器进行了仿真分析和硬件实现。

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％。
