Two kinds of models by estimating pool equations and panel estimation have been constructed. Based on the idea of Reduced Form Model, by adopting lags-adjustment or not, time-series dynamics models of the fluctuation of urban residential real estate market, in which the endogenetic and the exogenous sensitive variable include, have been estimated. In logarithmic form the models are applied in a case.

同时，借助缩约模型的基本思想，将住宅市场波动的外生和内生敏感性因素纳入到城市住宅市场的动态分析中，从纵向角度引入非时滞调整和时滞调整的两类模式，构筑了不同形式的住宅市场波动的时序动态模型，采用对数模型估算案例城市商品住宅市场的时序动态波动状况。

Under the hypothesis of stock price submitting to exponential Ornstein-Uhlenbeck process ,we solve the formula of pricing of stock and analyse the kind of the option formula, and then aiming at the blemish to suppose to interest rate before and considering the relation of the fluctuation of interest rate and the fluctuation of stock price , we bring up the model of the market interest rate and focus on analyzing the effect of the fluctuation of market interest rate on the option price based on the model.

本文首先在股票价格服从指数Ornstein-Uhlenbeck过程模型假设下，求解了股票的定价公式，分析了期权公式的性质，然后针对以往对利率假定的缺陷，考虑到市场利率波动与股价波动的相关性，提出了市场利率模型，并在此基础上，着重分析了市场利率的波动对期权价值的影响，求得了适合于期权有效期较长情形下的期权定价公式，并将该公式通过实例与著名的Black-Scholes期权定价公式进行了深入比较。

The tested results show that there is an optimal magnetic flux density for depressing effect on the level fluctuation .

实验结果表明磁场对结晶器液面波动的抑制作用有一最佳值，当磁场为0.5T 时液面的平均波动最小。

An early comprehensive attempt to incorporate the Schwabe cycle into a business cycle framework was suggested by William Stanley Jevons (18351882), who early in his career was a practicing meteorologist. In JevonsInvestigations in Currency and Finance, he discussed economic fluctuations and isolated three components of economic activity: seasonal fluctuation, business cycles and trends. Jevons attempted to statistically link the business cycle with fluctuations in sunspot activity.

早期努力将施瓦布周期并入商业周期的框架由早期是实习气象学家的William Stanley Jevons (18351882)提出在他流通与金融的研究一文中，他讨论了经济波动和经济活动独立的三个内容：季节性波动商业周期和趋势他还努力统计商业周期与太阳黑子活动波动的关系另外有由Jevons的儿子H.S。

Many factors are related to this fluctuate, one of them is the permanent magnet flux fluctuate.

造成转矩波动的因素有很多，其中永磁体磁链波动是一个重要原因。

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。

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。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
