Firstly, the approach formulates a cost functional to turn the inverse problem into a constrained minimization problem according to least squares criterion, then the resulting constrained minimization problem is transformed into an unconstrained minimization problem by using a penalty function technique, and then the closed Fr chet derivatives of the Lagrange function with respect to the properties are derived based on the calculus of variations, finally, one can solve the resulting problem by using any gradient-based algorithm and the finite-difference time-domain method.

该方法首先以最小二乘准则构造目标函数，将逆问题表示为约束最小化问题；接着应用罚函数法转化为无约束最小化问题；然后基于变分计算导出闭式的拉格朗日函数关于特征参数的Fr chet导数；最后借助梯度算法和时域有限差分法迭代反演德拜模型参数。

Furthermore, we define a convolution multiplication between characteristic functions of constructible subsets by using push-forward functor from the category of algebraic varieties over C to the category of spaces of constructible functions. We construct geometric model for "intrinsic symmetry" of the octahedral axiom in a triangulated category. Using it, we deduce the multiplication satisfies the Jacobi identity of Lie algebra and then realize infinite dimensional Lie algebras.

进一步，我们使用复代数簇范畴到可构函数空间范畴的pushforward函子，给出了可构集上特征函数的卷积乘法，并构造了三角范畴八面体公理的内蕴对称性的几何模型，最终证明了对于不可分解支撑有界可构集的特征函数，乘法满足李代数定义的Jacobi恒等式，从而给出了无限维李代数的实现。

Firstly, we suggest using context-free language to describe the start code string of MPEG-2 and using minimum-distance error-correcting parser to correct the errors in MPEG-2 start code string. This method hasn't been reported elsewhere. Secondly, side motion estimation rule is proposed for temporal error concealment and based on the rule, many new algorithms are proposed. Among which, the temporal error concealment method utilizing overlapped block motion compensation and side motion estimation rule has exceeded the best performance ever reported.

首先，提出用上下文无关语言描述MPEG-2起始码链，用最小距离误差校正剖析方法进行MPEG-2起始码链的识别与误差校正，该方法国际上尚未有同类报导；其次，提出了用边界运动估计准则进行时域错误掩盖，基于该准则提出了一系列新算法，其中基于重叠块运动补偿和边界运动估计准则的时域错误掩盖算法达到所有已知算法的最佳性能。

The cubic interpolation polynomial is got firstly in the given sub-range of the hydrophone's sensitivity-frequency curve by using the Akima curve smoothed algorithm, and the maximum of the polynomial is calculated in the sub-range by using the one dimension extreme value continued fraction algorithm, finally the frequency of the hydrophone is got.

频率测试是在灵敏度详细测试的基础上，采用阿克玛曲线光滑算法求出检波器幅频特性曲线在给定子区间上的三次插值多项式，再利用一维极值连分式法求出该区间上多项式的极值，从而求出检波器的频率值。

An index is calculated as the ratio of the economic loss estimated by using the continuity method and the economic loss calculated by using the discrete method with different seismic performance levels.The minimum number of performance levels is considered as the rational result when the index is within a prescribed small range.
