background: an effective method for management of large and bulky malignant tumors. this treatment modality is also known as specially fractionated radiation therapy (sfrt). in this treatment technique a grid block converted the open radiation field into a series of pencil beams. dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and mo...

Abstract By analyzing the degree of grain deformation FGH96 alloy under different plastic process parameters, as well relative frequency and distribution characteristics recrystallized core boundaries with orientation differences, comprehensively considering evolution law grains sizes, relationship between boundary is studied. The correlation nucleation mechanism grains, growth cores, related d...
