The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.

通过极小化输出误差目标函数获得了系统参数估计；提出了正交梯度搜索方法用于解决系统参数的非唯一性问题，正交梯度搜索的本质是在输入-输出等价类相切平面的正交垂空间更新系统参数；给出了用 L-M 算法进行参数优化的充分条件；提出的系统参数递阶优化辨识方法包括两步：首先用给出的自适应 L-M 算子正交梯度方法确定参数优化方向；其次由一维搜索方法计算最佳步长。

By analyzing discreditable behavior in the terms of economy, the reason was found out that discreditable behavior resulted from non-equivalent information, unclear property right and that the income exceeded the cost.

从经济学的角度对失信行为进行了分析，发现导致失信行为产生和蔓延的原因是信息不对称、产权不明晰以及失信所得的收益大于其成本等诸多因素的共同作用的结果。

Through social credit environment with actual examples, the pedagogue to see trustworthiness is real benefits, let not the sincerity to bring the deep-rooted non-equivalent loss in the whole society and build a cannot tolerate any discreditable behavior of atmosphere, so it not, without living space, accounting problems will then solved dishonest, accounting for possible once again for his social doing basic commitment.

通过社会诚信环境的治理，用实际事例让受教育者看到守信的是实实在在的好处，让不诚信者体会到失信带来的铭心刻骨的损失，在全社会营造一种不能容忍任何失信行为的氛围，这样，不诚信者就没有了生存空间，会计失信问题也就随之迎刃而解，会计才有可能再次承担起他对社会所做的基本承诺。

Further more, we get the necessary and sufficient conditions for the two-dimensional discrete system, where the permanence and extinction of the system are decided and only decided by the relationship of the non-delay coefficients in the system. Further, we for the first time find the equivalent permanence and extinction between the two-dimensional discrete Lotka-Volterra and its corresponding continuous system.

进一步，本得到了此类离散系统二维自治情形下，其持续生存和灭绝分别等价于系统非时滞系数构成的相应不等式；通过比较本文中二维自治Lotka-Volterra竞争系统的连续和离散两种情形的有关结论，首次发现这两类系统具有等价的持续生存和灭绝性质，建立了这两类系统之间的联系。

Finding out the maximum point of the equivalent plastic strain on each of the vertical lines, a group of discrete points on the critical slip surface will be obtained. Last, the discrete points are smoothed by means of the thin-plate smoothing spline; and the position of the critical 3D slip surface is determined.

最后，采用被称为薄板光顺样条(thin-plate smoothing spline)函数的插值方法对滑面上的离散点进行了插值光顺处理，在不指定边坡滑动模式和滑面形状的前提下就可以得到三维边坡的临界滑面。
