four of a kind
1.Firstly, the paper introduces the theoretical background and actual study of Activity-Based Costing (ABC) and Business Process Re-engineering (BPR). Secondly based on the theory of ABC drivers, modelling the producing process of a kind of cable enterprise with IDEF,and on the base of which,combines the redundancy activities in the producing process, and puts forword four kinds of calculating on costing drivers,then,instead of the hierarchical multilevel organization establishes flat producing process.
2.In the present study we used conventional CoMFA and introduced four routines of modified CoMFA, cross-validated R2-guided regional selection ( q2-GRS), all-orientation search (AOS), all-placement search (APS) and comparative molecular similarity indices analysis (CoMSIA) , to investigate a set of 18 pinusolide and its derivatives as a kind of newly discovered platelet activating factor (PAF) antagonist.
3.In Chapter 6, the target recognition is discussed by using the four kinds of the recognition feature of target, which are the inter-correlation of shadow images for the inhomogeneous target, the auto-correlation between the shadow image and the original shadow image for a kind of the target, the feature of the midline of shadow profile of the target and actual length of the shadow-profile of target.
5.Based on the social functions of Han Viet Dialect for thousands of years in Vietnamese society as well as the four main distinction features of language and language variety:standardization,autonomy,historicity,vitality , for the first time,we point out that Han Viet Dialect is a kind of Literature Language. It plays the role as the High Dialect of Vietnamese between the year 939 to 194S.
6.Result: Pure LBP has four water solubie polysaccharides,M W was 1.524×10~5.LBP was composed of 6 kinds of monosaccharides(Ara,Rha,Xyl,Man,Gal and Glc),galacturonic acid and 18 kinds of amino acids. Conclusion: LBP is a kind of complex polysaccharides consisting of acidic heteropolysaccharides and polypeptide or protein,and LBP has Glycan-O-Ser glycopeptide structures.
8.In order to validate of the two protocols T/TCP and ESSP, the author analyses and tests the four protocols UDP, TCP, T/TCP, ESSP in theory and reality. Thetesting process takes NetAnalyzer of EQ Information Technology Inc. as the testing tool, that is a kind of net supervisor and protocol analyzer software.
