  quasi-standard
This quasi-standard error (QSE) closely tracks the actual error in an example, and looks to be at least as accurate as a standard error based on random replication.
      
We also show that the quasi-standard error is not unreasonably large in its intended use.
      
A sufficient condition is given in order that a von Neumann algebra with cyclic vector is quasi-standard.
      
With the help of this result it is proved that a locally normal state with a cyclic and separating vector in the representation space gives rise to a quasi-standard von Neumann algebra.
      
Moreover, it integrates with the quasi-standard modelling tool Rational Rose which allows UMLbased graphical design of information models.

For a variety of reasons, a practical screw of which the main elements are more or less modified to be different from those demanded by standard screw series is usually a quasi-standard type screw. The open water performance estimation for such screw is given in this paper. Especially, for a non-standard thickness screw more practical analysesare carried out, and the formulae necessary for calculations together with the parameters are given here. By virtue of these, one can estimate the performance of non-standard...

For a variety of reasons, a practical screw of which the main elements are more or less modified to be different from those demanded by standard screw series is usually a quasi-standard type screw. The open water performance estimation for such screw is given in this paper. Especially, for a non-standard thickness screw more practical analysesare carried out, and the formulae necessary for calculations together with the parameters are given here. By virtue of these, one can estimate the performance of non-standard thickness screw simply with manual calculations.The use of this estimation method in the screw design is also illustrated in this paper.It has been found that the calculated results fitted the experimental data better than all other approximate methods.

According to conceit of author about classification of error,this paper describes to comprehend the classification of uncertainty in sugges-tion of INC-1 (1980), which suggested by BIPM working group on statmentof uncertainty. And it introduces a method of appraised uncertainty of B class.This paper advances that the unknown error in deterministic function andthe random error which don' t cause randomly fluctuation of measuring datacan deal with uncertainty of B class. Further it considers error function orcurve as a realization of ergodic stationary random process. So we can finethe pseudodistribution density of this error function or curve by analyticmethod or plotting method, which have been given in this paper. As a resultwe can use its pseudo-standard deviation to express uncertainty of B class.Moreover we can fine corresponding pseudo-confidence factor of confidenceinterval while it is neccessary.

本文从作者对误差分类的设想出发,来理解国际计量局不确定度工作组的INC-1(1980)建议中对不确定度的分类,并探讨其中B类不确定度的一种估算方法。文中提出未定的确定函数误差与未引起测量数据作随机变动的随机误差宜作B类不确定度处理。并设想将确定函数误差视为遍历性平稳随机过程的一个现实,以求得其准分布密度,且给出其解析求法与作图求法。从而可用其准标准差u来表征B类不确定度,必要时可求得相应的准置信因子k。

An intercomparison of four environmental samples analyzed by γ spectrometry was organized. Three samples consisted of standard or quasi-standard substances with known specific activities of some nuclides while the radioactivity of the other sample was unknown. The authors presents a new method, the model real time weighted average, used for determining the reference values of intercomparison and comparison with other methods.
