Through minimizing the Stein Unbiased Risk Estimate based on the function, the optimal threshold, varying with the signal and noise, is obtained in the Mean Square Error sense.

进而通过极小化SURE估计得到MSE意义下自适应于信号和噪声的最优阈值。

The optimal thresholds and neighboring window sizes are determined for every subband in the wavelet domain using Stein's unbiased risk estimate, and NeighShrink is also extended from orthogonal wavelet transforms to dual-tree complex wavelet transforms in this paper.

该文运用Stein的无偏风险估计，在小波域每一个子带为NeighShrink方法确定一个最优的阈值和邻域窗口，并将NeighShrink方法从正交的小波变换推广到对偶树复数小波变换。

In a transportation network supported by the Advanced Traveler Information Systems,the drivers equipped with ATIS are directed by a control center to select their routes so as to minimize the total network travel time,while the unequipped ones make the route choice decisions on the base of minimizing their individual travel times.

考虑一个被路径诱导系统支持的交通网络，装有ATIS的出行者接受交通中心的指挥、按照系统最优的原则选择路径，没有该装置的出行者根据个人成本最小的原则择路，建立了刻画这种混合交通行为的变分不等式模型，推导了混合交通行为网络的效率损失上界，并以多项式路段成本函数为例给出了一些上界的特殊值。

The safety path vector is an approximate measure of the number and distribution of the faults in the neighborhood and can be setup or updated through the n?1 rounds of information exchanges among neighboring nodes by consuming only n bits storage space.

其中SPVs的赋值可以通过n-1轮邻节点之间的信息交换来完成，且算法中各节点的存储开销仅为n bits，因此，SPVs是安全向量与扩展安全向量的一种扩展，具有比SVs和ESVs更好的记录最优通路的能力。

The improved Pareto multi-objective optimization with GA adopts non-dominated ranking, elitist preserve and niche approaches, and proposes individual vector module adaptive function as wash out rule. As an example, two duality functions are used to validate the two algorithms.

通过两个多元函数的最小值优化算例验证，两种方法均获得较为均匀分布的Pareto前沿，并且改进的Pareto遗传多目标优化算法由于采用了小生境技术，使得最优解的分布更加均匀，避免了局部收敛的问题。

The mPAP correlated nagatively to RVEF (r=-0 .6097, P＜0.001). For this reason, the measurement of RVEF by radionuclide ventriculography was regarded as reliable . Through stepwise regressive analysis we got the multiple linear regressive equation as follows

本文结果显示mPAP与RVEF呈显著负相关(r＝-0.6097，P＜0.001)，说明核素技术检查COPD、肺心病人的EF值是可靠的。mPAP与RVEF、SaO〓、PAD等多项无创检查参数相关，并通过逐步回归分析得到下面的最优多元回归方程
