1.The results were analyzed by the statistical software SPSS. Results:The detection frequencies of anterior, middle and posterior ethmoidal foramen (AEF,MEF,PEF) were 100%,42.9% and 99.5%.
3.Cribra Orbitalia on the Bronze Age Skulls from Yanghai Cemetery in Shanshan,Xinjiang
4.Conclusions: (1) There are variety in morphology of secundum ASD, such as oval, oblong, Swiss cheese, narrow and long and irregular.
5.The new test index of FA_p is presented to evaluate the percentage passing the sieve of 0.075mm and the rational index ranges for CA ratio and FA ratio fit for the SMA16 aggregate grading which perfect the evaluation of the percentage passing of the critical sieves in design gradation by Bailey method.
6.Methods:106 patients underwent consecutive axial scans by GE lightspeed MSCT and the mutiplanar reformation (MPR),three-dimensional (3D) reconstruction images were observed and measured to study the anatomic characteristics of ethmoidal foramen,involving its frequency of identification and location with AW 4.2 workstation.
7.Product introduction Series of BS undulate screen, which surface are made of more line-up and row peach shape screen pieces, its rotor is circumrotate by same direction and equal speed, the screen surface intervene turning make of levity screen hole, drive materiel above screen go forward with undulate form, thereby reach to separate effectively.
8.The FEM simulation of velocity distribution, viscosity distribution and pressure distribution of basket die flow channel was presented.
9.The paper studied the Bailey method for aggregate grading design and evaluation and recommended the sieve of 0.075mm as the minimal control sieve,and the indexes for design and evaluation of the SMA16 gradation. The road-use performances of asphalt mixtures were tested for gradation contrast before and after adjustment.
10.This machine adopts one pair of rotating grinding blade to grind form damp material into column-shape granule by stainless steel sieve cylinder which is provided for pelletize in next process.
