一致估计

The convergence of them is proved, i.e if the parameters estimation is consistent, then self-tuning fusion estimator will converge to the optimal fusion estimator with known model parameters and noise statistics, and the accuracy of self-tuning fusion estimator is higher than that of each local self-tuning estimator.

证明了它们的收敛性，即若ARMA新息模型的参数估计是一致的，则自校正信息融合Wiener估值器将收敛于当模型参数和噪声方差己知时的最优信息融合Wiener估值器，且自校正信息融合Wiener估值器的精度高于每个局部自校正Wiener估值器。

In 2008 the World Bank estimated that a global flu pandemic similar in its deadliness to the 1918-19 Spanish flu could kill over 70m people worldwide, and could cause the world economy to contract by 4.8%.

据世界银行估计，2008年全球性的流感的死亡数量与1918-1919年的西班牙流感中的死亡数可能一致，全球约七千万，全球经济也因此可能下降约4.8%。

How to quantitatively determinate the relation between system behaviors and parameters variations was an important problem of systems biology.In order to study robustness of NF-κB signal transduction networks,the parameters of system model were assigned to subject to stochastic distributions.

然而，包括速率常数和反应物初始浓度在内的许多参数都是通过实验测量或者根据文献推断得到的，即使对于那些完全通过实验来估计参数的模型，也不能确定参数的实际值与对应的生物系统是否完全一致。

The WBMS has continued to issue upward adjustments to its series for world primary aluminum consumption, and its total for 2005 now almost exactly matches CRU 's downwardly revised estimate.

就世界主要铝消费量来说，世界金属统计局WBMS已经继续发布向上的调整。2005年的总量现在几乎和CRU下降的估计是一致的。

In study of equational data on bipolar disorders, the application of linkage analysis was limited, but the results of else three statistical models were similar. They all suggested that the relation between DRD2P or COMT and bipolar disorders had no significance.

在平衡数据的双相情感性精神障碍家系资料致病基因位点的研究中，连锁分析的应用受到限制，而其它三种统计模型的结果一致，DRD2P和COMT基因位点与疾病的关系均无统计学意义，但随着样本含量的增大，广义估计方程表现了一定的优势。

仿真结果表明上述与信号模型相关的因素对DOA估计的精度有一定影响，与理论分析一致，且证实改进算法有效。

Under some moderate conditions, the prior estimate of the solutions of the system is obtained. Making use of constructing Picard iterative sequence, Doob martingale inequality, Gronwall inequality, Borel-Cantelli lemma and some fundamental inequalities, together with the uniform Lipschitz conditions, the existence and uniqueness of the solution for stochastic functional differential equations with infinite delay is derived on the interval t0,∞.

在适当的条件下，得到了随机泛函微分方程的解的先验估计；再结合一致Lipschitz条件，通过构造Picard迭代序列，利用Doob较不等式、Gronwall不等式、Borel-Cantelli引理及一些基本不等式，得到该方程的解在区间[t0，∞]上是存在且唯一的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
