 central angle
 Initial data obtained show the critical buckling pressure to vary as a power of the thickness and almost linearly with central angle. Parameters examined included thickness, central angle and toroidal radius. The desired functions are represented by the product of a power function of the radial coordinate and the unknown function of the central angle in the cross section. The lack of 13-day periodicity in the solar 10.7 cm flux is caused by its broad central angle dependence that averages out the 13-day variations and produces nearly sinusoidal 27-day variations. The critical pressure is expressed explicitly by a function of the radius of the inclusion and the central angle sublended by the half length of the crack; especially it is inversely proportional to the square root of the radius of the inclusion. 更多
