horizontal trace
1.BEHAVIOUR PATTER ANALYSIS AND ENVIRONMENTAL SIGNIFICANCE OF THE HORIZONTAL TRACE FOSSILS FROM THE SINIAN-CAMBRIAN BOUNDARY BEDS AT MEISHUCUN, YUNNAN,CHINA
2.In order to speed up the design of plough bottom surface, we have established the computing and drawing FORTRAN program. On the computer DJS-8 we have computed for the outline, the horizontal trace, the performance templet curves of plough surface. On the drafting machine DC300 we have drawn the graphs.
3.YH computer,a vector supercomputer,frequently uses parallel repeated operation and vector dual processing array technique. The vector algorithm may be used for the integral migration of 3D wave equation,it includes five essentials:(1)time-varying convolution of every horizontal stacked trace is made before summation;
4.Actual seismic data procession shows the efficiency of this method to increase the signal-to-noise ratio of horizontal stacked profile, especially for inaverage signal-to-noise ratio in pre-stack trace assemblage data.
5.DETERMINATION OF 25 TRACE IMPURITY ELEMENTS IN U_3O_8 BY HORIZONTAL ICP-AES AFTER SEPARATION WITH TBP LEVEXTREL RESIN CHROMATOGRAPHY
6.THE DETERMINATION OF TRACE Gd, Sm, Dy, and Eu IN Zr-Nb ALLOY BY CATION ION-EXCHANGE SEPARATION-HORIZONTAL ICP-AES METHOD
7.DETERMINATION OF TRACE Hf, Zr, Sc, Th AND Ag IN U_3O_8, BY HORIZONTAL ICP/AES AFTER SEPARATION WITH TBP LEVEXTREL RESIN CHROMATOGRAPHY
8.The sample is dissolved with mixed HNO_(3-)-HClO_(4-)-HF acid in pressure. Trace beryllium, chromium, manganese, vanadium and zirconium content in rocks can be simultaneously determined using horizontal ICP-AES with calibration curve method.
