查询词典 tri-angular thread

It also introduces the discrete ordinates couple-solving method (DOT-BSTP-DOT) which uses the half-symmetric angular quadratures for core geometry and the quadratic S〓 biasing angular quadratures for duct geometry. Calibrations for several types of duct are carried out and the schemes of XPR epithermal neutron filter are successfully designed. The other international popular code ANISN is also exploited and modified.
