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 Ca〓 oscillations occured before GVBD were associated with the resumption of GVBD, because when the oocyte was cultured in medium with hypoxanthine, no Ca〓 oscillation occurred, without hypoxanthine the oscillations occured again.

这些Ca〓波动与卵母细胞的GVBD有关，被次黄嘌呤抑制于GV阶段的卵母细胞不出现这种形式的波动，当再次培养于无次黄嘌呤的培养液中则又出现Ca〓的波动。

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。

The macroeconomics has demonstrated the relation between investment and economical growth. Investment affects the general demand and GDP via multiplicator. On the other hand, the fluctuation of GDP affects investment via accelerated vector. There exists a relation between GDP and investment. A macroeconomical seasonal fluctuation represents a slack or climax under the effect of GDP and investment. Chronically, investment and GDP growth will arrive at equilibrium, and GDP shows disciplinarian fluctuation.

宏观经济学论证了投资与经济增长之间的关系，投资通过乘数影响总需求进而影响国内生产总值，而GDP的向上或向下的波动又通过加速数影响投资，二者是动态的关系，在投资乘数和加速数的共同影响下，出现宏观经济的周期性的波动，表现为宏观经济的高涨和萧条，投资和经济增长在长期将达到均衡状态，使得GDP呈现出有规律的波动。

In the research of dynamic difference, based on the factors analysis of house price level, constructing similar and normal error correction model, the paper studied the determinant of short-run dynamics, and analyzed the reason of difference in autocorrelation and mean reversion.

在住房价格短期波动差异研究中，在城市房价水平影响因素分析的基础上，通过构建类似和标准误差修正模型，考察房价短期波动的决定因素，分析了房价波动自相关和均值回复表现差异的原因。

The exercise settlement value for VIX options (Ticker: VRO) is a Special Opening Quotation of VIX calculated from the sequence of opening prices of the SPX options used to calculate VIX at settlement.

行使解决价值波动率指数期权是一个特别开放报价计算出来的波动率指数的顺序开放价格指数来计算期权波动率指数在解决。

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。

In the analysis, a nonlinear wave vibration equation of the thin cylindrical shell including damping and items due to geometric nonlinearities was established and then transformed by Galerkin's method. With different combinations of modes different nonlinear differential equations in modal coordinates were obtained. The Runge Kutta method was used to solve the equations numerically and some features of nonlinear wave vibration were discussed.

在研究过程中，首先，考虑阻尼并引入几何非线性项，建立薄壁圆柱壳的非线性波动方程，然后，采用Galerkin方法对波动方程进行转换，选取不同的模态组合，得到相应模态坐标下的非线性微分方程，最后用Runge-Kutta法进行数值计算并对圆柱壳的非线性波动振动特性进行了分析。
