This paper is concerned with two problems: First, a formula is derived to estimate the error of system identification from the autoeorrelative function of stationary random disturbances and that of pseudo-random sequences. It can be used to select the type of pseudo-random sequences to be used for quick identification with a given error.

本文讨论了两个问题：(1)导出了平稳随机干扰的自相关函数、伪随机序列的自相关函数和系统脉冲响应辨识误差之间的定量关系式，可用来选择伪随机序列和估计试验误差。

This paper describes a demarcation and decoupling technology of helicopter bearingless tail rotor flexible beam,this technology can be used to solve the problem of flapping bending moment and lag bending moment coupling that encountered in bearingless flexible beam fatigue test,it also can be used to separate each test load component on the section effectively and to reduce the test error.

本文介绍了一种直升机无轴承尾桨柔性梁标定与解耦技术，该技术能有效地解决无轴承尾桨柔性梁在试验中挥舞弯矩与摆振弯矩的耦合问题，并能有效分离截面上各分项试验载荷，减少其试验误差。

The results from an example showed that the unbiased estimate of error variance could be obtained so that polygenic variance and polygenic heritability could not be underestimated. Moreover, the AIC values by using the average of two replications were less than that by using the observations of a replication.

在试验设计为重复内分组随机区组设计时，通过甘蓝型油菜初花期的遗传分析表明：这种方案的试验误差方差估计值无偏性好，可避免多基因方差和多基因遗传率被低估；重复观测值平均数的分离分析的AIC值低于利用单一重复资料的AIC值。

After studying analysis of variance on single factor and double factor,this paper reveals that if the difference between levels of the primes exist noteworthily is mainly depended on the sum of its experiment effects or variance of experiment effects and stochastic difference.

0引言 在试验设计时设置重复试验，能够估计试验误差；重复试验次数越多试验误差越低，试验精确度越高。一般认为，适宜重复次数应保证使误差项自由度至少为12，否则F检验或t检验的临界值上升很快，难以呈现显著性川。

To analyze the experimental results, the four operating conditions that influence mean particle size and size distribution, filtration time and the rate of hydrolysis of titanyl sulfate solutions are evaluated, four fitting models between responses and its influence factors are obtained. Optimum operating conditions are predicted. An experiment for validation of predicted conditions was carried out, and confirms the estimations are correct.
