| 求翻译一段文字谢谢Solar-grade boron doped silicon has been directionally solidified in a vertical gradient freeze-type furnace equipped with KRISTMAGs-heaters to study the influence of travelling magnetic fields (TMFs) on the ingot quality. As-grown silicon ingots of 22 x 22 x 13 cm3 in volume were cut vertically and analysed. Information was obtained on the curvature of the melt-solid interface，the grain size distribution，the content of SiC and Si〗N4 particles and the electrical activity of defects. TMFs were used to enhance melt stirring and to control the growth interface shape. Primarily inclusion-free ingots were solidified with grains of several centimetres in size. |
