FIELD: medicine.;SUBSTANCE: patient's blood is analysed for the absolute concentration of CD57+B mm (X5) and CD4+CD25+Treg in mm3 (X4) phenotype cells, and the levels of spontaneous interleukin-6 in pg/ml (X3), interleukin-8 in pg/ml (X2) and interferon-y in pg/ml (X1) ...
若令β=(x1,x2,x3,x4)T,则W⊥就是齐次线性方程组的解空间. 易求得该方程组的一个基础解系为 ξ1=(1,0,1,0)T,ξ2=(-2,-2,0,1)T 故 W⊥是子空间,由于线性空间是由其基向量生成的,所以,要求W⊥,关键是求W⊥的基.反馈 收藏

任何 x ∈ N (A) 滿足 Ax = 0, 或寫成向量方程式 x1u1 + x2u2 + x3w1 + x4w2 = 0 1 進一步將 ui 和 wi 分離: x1u1 + x2u2 = −x3w1 − x4w2 等號左邊的向量屬於 U , 而等號右邊的向量屬於 W , 所以此向量屬於 U ∩ W . 由題 (a) 結果, 可繼續化簡 A 至最簡列梯形矩陣,...
