波动

Based on the HP filtering analysis,the stylized facts and important influence of China's energy efficiency fluctuations are detected in the article,and then a dynamic stochastic general equilibrium model is developed to describe the mechanism of energy efficiency change in the short run.

本文从波动角度分析了中国能源效率的变化，特别强调波动成分对能源效率的短期影响，并在动态随机一般均衡框架下构建能源效率的机制决定模型，以探讨不同冲击对中国能源效率波动的作用差异。

In the DDMRS-GARCH model, the transition probability of the volatility state variable is not only related to the volatility state, but also to the duration of the volatility state.

在DDMRS-GARCH模型中，波动状态之间的转移概率不仅与波动所处的状态有关，而且与波动状态持续的时间有关。

The call for flexibility in last September's Group of Seven (G-7) communiqué caused the volatility implied by option contracts on the yen to rise temporarily (Figures 2.12 and 2.13). The February 2004 G-7 communiqué highlighting the undesirability of excess volatility helped to dampen volatility expectations.

去年9月份的七国集团（G--7）公报呼吁灵活性，造成日元期权交易暂时上升所隐含的波动。2004年2月份强调过度波动不可取的七国集团公报，有助于阻抑各种对波动的预期。

A simplified kinematic model on locomotion of the undulatory long dorsal fin propulsion is based on the the observation and experimental data.

在"尼罗河魔鬼"巡航游动试验的基础上，通过对鱼体几何形态和柔性长背鳍波动的运动学分析，建立了"尼罗河魔鬼"长背鳍波动推进的简化运动学模型，并利用大摆幅伸长体理论分析了长背鳍波动推进的水动力学特性。

The cycle undulatory theory tell us that there is certain periodicity in economical development. This kind of periodic performance almost simultaneously expands for the many economic activity, then universal declines, contracts and recovers, thus influend economy development.

周期波动理论认为经济发展存在周期性，这种周期性表现为很多经济活动差不多同时扩张、继之以普遍的衰退、收缩与复苏，从而影响经济的发展；而景气理论则是在周期波动理论的基础上，构建景气指数来监测宏观经济受经济周期波动的影响。

By analyzing and comparating of every kinds of coal balter equipments,based upon the as-sets of the fluctuating balters and roller balters,a new kind of coal balter- fluctuating roller balter was designed and installed.

通过对各种筛煤设备的分析比较，根据波动筛和滚轴筛的优点，设计安装了一种新型筛煤设备——波动滚轴筛，并介绍了波动滚轴筛的特点和技术改造方案。

The cogging force ripple is analyzed in different slot structure quantificationally and the way to reduce cogging force is also studied.

在此基础上，定量分析了不同齿槽结构下的齿槽力波动，研究了消除齿槽力波动的方法，验证了采用近槽极配合的分数槽是减小推力波动的一项非常有效的措施。

Statistic analysis indicated that three kinds of irregular components show complicated random characteristics, and their probability density distributions change with increasing gas velocity, that is, irregular occurrence time fluctuations of all three kinds of elements of heterogeneous structure (the dilute phase, the dense phase and the dilute/dense cycle elements) evolve similarly from symmetric distribution similar to Gauss distribution at low gas velocities to double-peak distribution at medium gas velocities, and become dissymmetric single-peak distribution at high gas velocities.

相关分析表明：动态行为中的三类非规则波动呈随机性；直方图分析表明：随表观气速变化，非均匀结构的各种非规则波动的概率密度分布均具有复杂的演变；其中，对于时间非规则波动，其演变趋势是：小气速下的单峰分布、中气速下的双峰分布和高气速下的非对称单峰分布。

; 3 younger Dryas Only has reflection in the hundred-year-scales climatic curve, it is not evident in the curve of long period; 4 in the hundred-year-scales climatic curve, the last glacial maximum fluctuation as frequuently and 18-28KaBP was the stage in which the frequency fluctuation was the largest.

；（3）新仙女木事件仅反映在百年尺度的气候曲线上，在较长周期的饿曲线上不明显；（4）在百年尺度的气候曲线中，末次冰盛期气候波动频繁，其中18-28KaBP 是频率波动的最大阶段，但随着周期尺度的加大，气候的波动频率逐渐趋于均匀。

Because we use the two factors,γ1 andγ2, to explain monetary policy and another two factors, m and n, to explain market volatility exogenously, these results can characterize the relationships in government bond market between volatility and monetary policy, liquidity and returns well.

实证结果表明，模型中引入利率调整因子γ1、准备金率调整因子γ2及流动性因子m和n作为外生解释变量，能够较好地刻画我国货币政策对国债市场波动的冲击、市场流动性对国债收益率波动的影响及国债收益率波动与收益率的关系。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
