The R2 and Adjusted R2 tell us whether the regressors are good at predicting, or "explaining" the values of the dependent variable in the sample of data on hand.

R2和调整过的R2告诉我们，解释变量是否很好地预测了，或"解释"了，手头数据中被解释变量的值。

Based on the samples of over 1000 listed companies at the beginning of Reform of Non-tradable Shares in 2004 and 2006, the share proportion CR1 of the largest shareholder, Z index calculated as the ratio of share ratio of top 2 shareholders and H10 index calculated as the sum of square of share ratio of top 10 shareholders, and Tobin'Q reflecting the value of target company are sele

本文以股权分置改革开始的前后两年即2004年和2006年的一千多家中国上市公司为研究样本，选取第一大股东持股比例CR1、前两大股东持股比例的比值Z指数以及前十大股东持股比例的平方和H10指数作为衡量大股东控制程度的指标，采取托宾Q值来作为衡量公司价值的指标，把公司规模、财务杠杆和第一大股东性质虚拟变量作为控制变量，建立回归方程，实证结果发现三次？

To simplify and reduce the effort required for solving control equations, separation of time-space variables is invoked.

在此基础上，在整个时间空间上构造了迭代求解方法，将问题化为局部状态变量修正和全局控制变量求解问题；从而形成了有限变形问题过程最优控制计算方法的理论基础。

First, for a given integer value of the objective function, the lower and upper bounds of the variables were determined by the optimum simplex tableau of the linear programming relaxation problem. Then the conditions on the bounds were added to the constraints as cuts to the associated objective function hyperplane. Finally, a branch procedure of the branch-and-bound algorithm was applied to finding a feasible solution on the objective function hyperplane.

对于给定的目标函数整数值，首先利用线性规划松弛问题的最优单纯形表确定变量的上、下界，然后将变量的上、下界条件加入约束条件中对相应的目标函数超平面进行切割，最后应用分支定界算法中的分支方法来搜寻目标函数超平面上的可行解。

To overcome the long test time and big error in single variable open loop step test method, a novel identification method based on asymptotic theory is presented.

为克服传统单变量开环阶跃测试法测试时间长和误差大的缺点，提出一种基于渐进黑箱理论的多变量辨识方法。

In the process of solving it, the slack variable was introduced, which has an important physical meaning. If the slack variable of the solution has a larger value, it means there's an unknown water source.

在模型求解过程中引入的松弛变量具有重要的物理意义，如果解中松弛变量取值较大，则意味着存在未知水源。

Within the optimization of systematic level of cooperated optimization, the slack variable is introduced to let the restraint of consistency equality be transformed to the restraint of non-equality. The value adoption of slack variable will affect the convergence speed in the optimization of systematic level.

在协同优化的系统级优化中，引入松弛变量，将一致性等式约束转化为不等式约束，松弛变量的取值影响系统级优化的收敛速度。
