To solve problem of die lock area appeared in process of stamping, this paper presents method of coordinate comparison to qualitatively detect die lock area, and set out mathematical model to quantitatively adjust the stamping direction. The methods are utilized to a stamping part, and the results show the methods can effectively solve the die lock area problem.

Recent studies suggest the determinations of clinical laboratories must be made more precise than at present. This paper presents a means of examining benefits of improvement in precision. To do this we use a mathematical model of the effect upon the diagnostic process of imprecision in measurements and the influence upon these two of Importance of Diagnosis and Prevalence of Disease. The interaction of these effects is grossly non-linear. There is therefore no proper intuitive answer to questions involving these matters. The effects can always, however, be calculated.Including a great many assumptions the modeling suggests that improvements in precision of any determination ought probably to be made in hospital rather than screening laboratories, unless Importance of Diagnosis is extremely high.
