请各位高手帮我把着段文字翻译成英语啊 酬谢两百分

[ Abstract ]: This article mainly elaborated can the opposite angle matrix condition, how as well as the opposite angle matrix is asking a matrix opposite angle the higher mode power matrix, the known characteristic value and the latent vector asks the matrix, to ask the determinant, the judgment matrix to be similar and so on the aspect application.

[ Key word ]: But opposite angle matrix, solid symmetrical matrix, diagonal matrix. But diagonal matrix and its utilization

【摘要】： The principal expounded on the syndrome can be matrix conditions, how will a matrix of matrices in Alport syndrome and for the economy to high matrix, the value and characteristics of the known characteristics of the vector for the matrix, and determinant, matrix similar judgement in the application.
