First discarding the thought of fitting by AR model, the ARMA model is fitted by a high order MA model using Gevers-Wouters algorithm on the basis of related functions of ARMA model. Then according to the parameters of the fitted MA model, the ARMA model parameter estimation through solving a system of antipathic linear equations using the least squares method is obtained.

This value is prescribed only vaguely by many authors with no reference to any significance level. This paper will give out an asymptotic critical value in a fixed significance level and an asymptotic p-value for testing by means of extreme value theory in order to detect outliers in AR model.

本文运用极值理论给出诊断AR模型异常点选取临界值的分布近似方法，这种方法选取的临界值可保证控制在一定的显著性水平下，而且还可以计算出检验的渐近p值，比一般仿真选取的临界值更科学合理。

Moreover, after being followed up for 3 years, 49 patients who received regular SIT have less possibility to suffer from asthma than those of 23 cases patients who had irregular SIT, and the difference between them was statistically significant (P.01). For AR patients complicating with asthma, their asthmatic symptoms and physical signs had been improved after SIT. It was increasingly reduced for the level of TIgE, SIgE, and ECP in serum of AR patients after SIT.

此外，观察期满3年的49例接受系统免疫治疗的患者与未系统治疗患者23例发现，前者继发哮喘的几率低于后者，两者比较差异有统计学意义(P.01)；对合并有哮喘的AR患者经SIT后，哮喘症状体征有改善；患者血清TIgE、SIgE和ECP在SIT治疗后水平逐渐降低。

The six data in the age spectra defined an 40 Ar 39 Ar isochron which gives an age of 1862±37Ma.

这一结果表明，虽然变斑晶石榴石中仅仅在显微矿物包体、流体包裹体和晶格缺陷中赋存少量的 K+，但其生成的 4 0 Ar*仍然能够形成稳定的年龄谱。

It was found that sialon thin films deposited in ar and n2 atmosphere have higher relative dielectric constant, dielectric dissipation and leakage current density than those deposited in ar and o2 atmosphere.

发现在ar/n2气氛中沉积的sialon薄膜具有较高的介电常数，漏电流密度和介电损耗也稍大。

In order to establish the complete dynamic simulation model for the heat recovery steam generator and develop an advanced drum level controller, the methods of probability and time series were used to analyze the field data on drum level sloshing noise. The mean value of the drum level was removed and the field data was de-trended to get the true sloshing noise. Meantime, the AR model was set up for the drum level sloshing noise, and simulation results show that the model realizes matching simulation of the drum level noise signals in the power spectrum. The model can also match the drum level noise successfully in the time domain.

为建立完整的余热锅炉系统动态仿真模型，并基于此模型开发先进水位控制器，采用概率统计和时间序列分析的方法，对现场采集的汽包水位晃荡噪声信号进行了分析，去除汽包水位均值和趋势以获得真实的汽包水位晃荡噪声，建立了相应的汽包水位晃荡噪声仿真AR模型；模型的仿真结果表明：AR模型从功率谱上对信号数据进行了匹配模拟，且使用该模型作为噪声模块在时域上对汽包水位晃荡噪声信号进行了成功匹配。
