查询词典 mean time

In this dissertation , the methods of prediction and parameters\' estimation based on stationary multivariate autoregressive models AR(p are studied systematically. Some properties of these methods are formulized.In the first part, it introduce some basal conceptions about multidimensional stationary time series, contained the estimation and property of mean vector and auto-covariance function. Then the stable condition of multidimensional AR models are discussed.

本文主要研究了多维平稳序列自回归模型AR的参数估计及其相关的统计性质，具体内容如下：第一部分，介绍了多维平稳时间序列及其均值向量和协方差阵函数的概念，并引入了多维AR模型及其数字特征，在此基础上给出了模型的平稳性条件。

The results show that the entanglement of field-atom reduced to a stationary value with time evolution and the entanglement between two modes increase to another stationary value with intrinsic decoherence, and the values only depend on the two-mode photon number and mean photon number.

结果表明，存在内禀退相干时，随着时间的演化，场一原子纠缠逐渐减小到一个确定值，而模间纠缠逐渐增大到一个确定值，两者演化的最终值只取决于双模光子数差和平均光子数，而与内禀退相干因子无关。

The possible inuence of mainly immunological risk factors early after transplantation leads to manifestation of CAN in a shorter period. 4. The study showed no impact of C4d expression on mean serum creatinine levels at the time of biopsy and during 1-year observation. More patients with peritubular C4d deposition lost their grafts during the study period. 5. Deficiency syndrome-type with CAN usually are spleen-kidney Qi deficiency and hepatic and renal Yin deficiency; Sthenia syndrome with CAN usually are syndrome of blood stasis and damp-heat syndrome

并且发生CAN时间早于阴性组；体液免疫因素在慢性移植物肾病早期可能是一个重要危险因素；4、两组的肌酐水平在穿刺时及穿刺后1、3、6、12月没有统计学意义，但C4d阳性组穿刺后1年内失功率高且预后差；5、慢性移植物肾病患者的中医证型特点是本虚标实；本虚主要是脾肾气虚、肝肾阴虚，标实主要是血瘀、湿热。

If you are the lovers of in the same storm-tossed boats, and once owned beautiful happy time, so pleasing didn't ago don't see because of various layer after layer resistances but the cringes, gave up to continue to pursue of the wishes mean forever lose this together bright scenery in the moment.
