expression precision
1.From the analysis and the corresponding discussion, it is concluded that the new expression has a high precision and can construct multi-attribute AVO crossplottings, and that one can easily construct such non-conventional seismic attribute sections as and fluid factors, shear modulus, and compression-to-shear-wave velocity.
2.Based on precision machining,the concept of edge quality of parts is put forward and the measuring methods of edge quality didcussed. The necessity and practicability of classification,quantitative expression and unified standards for the edge of precision parts are described in detail.
3.In this paper, the GDOP(geometric dilution of precision) expression of area navigation system is deduced.
4.2. 5 X 105/L of Dane particles. Specificity and precision of the assay was very high. Using polyclonal anti-PreSl antibody could inhibit in combination PreSl synthetic peptide,gene expression PreSl protein,purified Dane particles and PreSl antigen positive serum with coated antibody, separately.
