In inner loop,we use a modified conjugate gradient algorithm and a restarted technique; in outer loop, the Morozov's discrepancy principle is used as a stopping rule.

该方法的内层循环采用修改的共轭梯度法，并使用重开始技巧；外层循环使用Morozov偏差准则作为停机准则。

As an application in engineering, a natural stopping rule to operational testing based on Bayesian method is proposed.

作为测试的工程应用，对于常用的运行测试，我们提出了一个基于Bpesian 方法的自战的停止测试原则。

An average cost and merging stopping rule are given in adjacentregion merging.

避免了由于水分线算法对噪声的敏感而产生过分分割。

The use of a 24-week retreatment stopping rule did not affect SVR rate.

使用24周停止再治疗规定并未影响SVR率。

The algorithm requires the bound of the eigenvalues of the Hessian can be estimated and uses the bound to determine the stopping rule.

算法要求函数的Hesse矩阵特征值的界可估计，并利用该界确定算法的终止条件。

And the new rule can simulate the error level of the righthand in the linearized equation nicely. Combine the new stopping rule and using the implicit iterative method in the inner iteration, we get a new method.

这个新的准则结合在内层采用隐式迭代法，由此得到的新方法与Tikhonov方法和Bakushinskii方法进行了比较，结果显示了该方法的优越性。

Thirdly, under the condition with noαpriori smoothness, in order to obtain the optimal convergence rates, it is not practical to use theαpriori rule. And it is necessary to use the a posteriori stopping rule which not only depends on the error boundδbut also on the perturbed data y~δ.

再次，在没有先验的光滑性信息情况下，为了获得最优收敛速率，利用先验选取准则则变得不再实用，而利用不仅依赖于误差界δ而且依赖于扰动数据y~δ的后验停止准则是必要的。

Base on the classical problem of the theory of optimal stopping──the secretary problem,k-th choice problem is worked out(k managers choose k secretaries ).The optimal stopping rule is given,and we proved that the optimal value of probability is the kth item of Poisson distribution with parameter k.i.e.e￣-K/k!.

从最优停止理论的经典问题──秘书问题出发，构想了K个经理从N个姑娘中各选一秘书的问题，证明了其最优规则，得出了概率最优值是参数为K的泊松分布的第K项，即e￣k￣k／k从！

Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.

因此，目前最常采用的是「反覆多重加权」的方式，但「反覆多重加权」实际执行时，最大的问题在於其检定方式是透过卡方检定，通常只要其检定P值大於0.5，就认定样本与母群一致，而未考虑一个最佳化的加权值。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
