It has been shown by the test that macroscopic inhomogeneous draft may occur in the cold ro-lling of strips if the parameter l′/h is less than a certain value. The coefficient n_f given by the the-ory of homogeneous deformation does not seem proper and should be modified by an amount of△n_f∝(l′/h)~(-1). The statistical model of n_f taking account of inhomogeneous deformation given in this workis not only proper for cold rolling strips, but also for hot rolling sheets and plates rolling.

实验证实了当l′/h小于一定值时,即便对于冷轧板带,也会出现宏观的不均匀变形,基于均匀变形假设导出的n_f理论解不适用,必须给以校正量Δn_f∝1/(l′/h)。本文给出的考虑不均匀变形影响的n_f统计模型不仅适用于冷轧机组,也适用于板带热连轧机组与中厚板轧制。

This paper derives rigorous F and T statistics which are used for the global test of outliers and for the test of each outlier immediately and directly after F-test respectively. Then an example is given for the purpose of comparison with the methods in [1,7 ].It can be seen that the method presented in this paper is rigorous in theory, feasible in practice and better than the methods [1 , 7].

本文首先导出了严密的F和T统计量,F统计量可用于粗差的整体检验,而T统计量可用于F检验后的各单个粗差的检验。然后给出一个算例,且与[1,7]中的方法进行比较。可以看到,文中提出的F-T法在理论上是严密的,在实用上是可行的,因此,它优于现有的几种方法。

We discusse the distributions latent roots of matrix-ratio under the gener- alized noncentral Wishart distribution for elliptically contoured distributions. Also, we have obtained the probability density function of the latent roots of generalized noncentral F estimate in general-cases.
