The models of permanent and instantaneous failures,which bring the indeterminable delay in interlock information transmission,and the models of repeating interlock information transmission and delay are set up.

在数字化变电站中，分布式联锁功能采用分布式模式实现[1]，即通过网络交换分布在多个物理设备中的不同逻辑节点间的联锁信息，并使用这些信息进行正确协同操作来实现。

The data were measured in 232 permanent sample plots. With the data of permanent sample plots, the parameters of transition probability and ingrowth models were estimated, and some models were compared and partly modified.

通过大量的省级固定样地资料，对林分生长转移概率模型和进界生长模型进行了参数估计，并对模型进行了比较和修正。

Based on modern option pricing theories,Black-Scholes and Merton option pricing model are used to study the pricing of the structured products,and its design,characteristics and risk are studied respectively.Based on Black-Scholes and Merton option pricing models,I also use the checking method to estimate the parameters of the model following real prices data,And calculate the theoretical price.Then,I compare the real and theoretical prices of the two pricing models.The results show that the effects of the Merton option pricing model are superior to the Black-Scholes option pricing model.Moreover,It shows that Hong Kong stock prices are also affected by the instant messages,and the jump phenomenon may exist in Hong Kong stock market.

本文以香港衍生品市场上三种主要结构性产品结构性票据、牛熊证和衍生权证为例，探讨了结构性产品的设计、特点、风险和定价，以现代期权定价理论为基础，以B-S和Merton两种期权定价为基础，根据市场价格经过校验得出模型隐含的参数，编程计算出两种定价模型下的理论价格，并将其实际价格和理论价格进行了比较，结果显示：Merton定价模型的效果要优于Black-scholes定价模型，说明香港市场的股票价格也可能受即时信息的影响，存在跳跃现象。

The human heart is the center of the cardiovascular system. Integrated with mechanical, electrical, neural and biochemical properties, the heart is difficult to model, and there is no ideal integral model now. The developed electrical models haven't considered the mechanical properties and blood flow process in the heart; while the mechanical ones have normally deal with the heart in the diastole period, and the electrical activity was simplified too much although some mechanical models have investigated the heart during systole.

心脏是循环系统的核心，它集机、电、神经和生化控制于一体，建模难度很大，目前尚无较理想的统一模型；心脏电生理模型未与心脏的机械动力过程和血液流动过程联系起来；而心脏力学模型大都只研究舒张期的力学特性，即使研究收缩期心脏的力学问题，也往往对心电兴奋做了许多简化假设。

In this paper,we use the fuzzy integral as the combination operator,give a kind of combination forecasting model that is on fuzzy integral,this model can reflect both the "importantance" of every models and the of the models.

本文利用Choquet模糊积分作为组合算子，给出一种基于模糊积分的非线性组合预测模型，该模型既能反映各种预测模型的"重要性"，又能反映各个预测模型之间的交互作用，并用此模型给出中国卫生总费用的预测。

This sort of models covers the shortcoming that the traditional production-inventory control models only show intermittent production policy.

这类模型克服了传统生产库存模型仅提供间隙性生产策略的缺陷。

Attempting to cover the full spectrum of tuning issues with a single, comprehensive model is bound to fail because of the lack of sufficiently accurate mathematical models or the intractability of advanced models.
