1) stochastic volatility
随机波动
1.
Basing on the theory of system,epistemology and of feedback control,a new security pricing model-stochastic volatility pricing model(SVPM) with jump and feedback,is proposed by amending a defect lying in the original models that neglect the important events happened frequently in financial markets,and by importing the interaction between investors and security price.
基于系统论、认识论、反馈控制论,在传统随机波动价格模型的基础上,通过修正其忽略“现实金融市场中,大事件发生比较频繁”这一事实的缺陷,同时引入证券投资者与证券价格之间的交互作用,提出一种新的证券定价模型——带跳及反馈的随机波动模型。

2) random fluctuation
随机波动
1.
To describe the characteristic of turbulence as 3D transient phenomenon with random fluctuations which is highly nonlinear, turbulence modeling ranging from approximate to highly rigorous was proposed.

结果表明:土性指标变异性并非土体分层后层与层之间土性指标的差异,而是层内土性点与点之间的空间变异;相对于传统随机变量的建模方法,这种空间变异性用随机场理论建模更加科学合理;随机场理论用空间趋势函数和随机波动分量分别表征土性指标的确定性部分和随机扰动部分,通过去趋势化处理,可把握土性参数不确定性的核心;实例分析显示,本文提出的方法可更加精确地了解土性参数的不确定性,为可靠性理念在实际工程中的应用提供有利的途径。
