The equivalence, performance bounds, existence, uniqueness and necessary condition of ME control are studied to show the ME method to be reasonable, applicable and effective.

ME方法是一种全局分析法，它不仅包含了MSE和MAP准则，且由于全文在整个推导中并未假定高斯性、线性和非时变等，因而原则上适用于诸如非高斯、非线性、时变等传统方法难以处理的复杂系统；不仅适用于工程系统，将其推广到决策、社会、经济等领域会更为自然和切合实际。

The features of the fractured medium and the rock matrix in the fractal composite reservoirs are describes with the fractal dimension (which describes the geometric features) and the fractal index (which depicts the connectivity of the fractal fluid flow network); An analysis mathematical model of well testing is proposed for inconstant flow rate with the closed outer boundary and the wellborn storage and the skin effects.

It is difficult to control a single inverted pendulum system because of the characteristics of multi-variable, nonlinear and absolutely instability of the system. A controller based on adaptative neuro-fuzzy inference system is designed by using Matlab/Simulink software in the paper. For the sampling data the hybrid algorithm of back propagation algorithm and least squares algorithm is applied in the paper. Thus the parameters of membership function are adjusted and all of the fuzzy rules are generated automatically.

For the models by MMFI is a nonlinear differential equation with variable coefficients and the 'nonlinearity' brings discommodiousness to analyse the nature and quantification of a control system, it applies brim linearization method to better MMFI. By transforming 'triangle wave' membership functions of the base elements into 'rectangle wave' membership functions, we get three models which represent different aspect respectively. By simulating second order system and analysing the errors of the results, a conclusion is drawn, that is, the model obtained by brim linearization method has a good precision in contrast with the real model.

由于模糊推理建模法得到的模型是变系数非线性微分方程，这种&非线性&对该控制系统的某些定性或定量分析带来不便，因此应用边缘线性化方法对模糊推理建模法进行改进，将基元的隶属函数由&三角波&改成&矩形波&，从而得到了三个模型，这三个模型各有侧重，通过对二阶系统进行仿真，分析仿真结果，从而给出了关于边缘线性化方法的结论，即由边缘线性化方法得到的系统模型对该系统的真实模型有较高的逼近精度。
