test scope
1.The test mechanisms of capacitor evenness tester and EIB photoelectric yarn appearance tester are analyzed. The capacitor evenness tester gives out the mean volume or mass of yarn section in test scope, but the EIB photoelectric yarn appearance tester reveals the diameter variation of yarn projection area, these two methods reflect the different property of yarn evenness, and their results are not in be in accordence.
3.Ultraviolet absorption detector, PhotoDiode Array detector (DAD), fluorescence detector, and electrochemical detector are optional detectors, response value of which is relative to not only quality of the object under test, but also structure of the compound; refractive index detector and evaporative light-scattering detector are universal detector, responding to structure of all compounds; evaporative light-scattering detector is quality-type detector, whose responding value only relates to quality of the object under test for compounds with similiar structures; PhotoDiode Array detector (DAD) can, at the same time, record absorption spectra of the object under test in a prescribed wave scope, consequently, it can be used in spectrum control and inspection of purity of chromatographic peaks of the object under test.
9.In this paper,we make a comparison between an advanced mathematics test paper of our institute and an HSC advanced mathematics test paper of New South Wales,Australia,1998.We gain some understandings of the differences in scope of knowledge,mathematics competence and testing style,and make proposals for optimizing this course.
