34、W9R9H3E5G1离散数学试卷（九）60 解：0000000010100000100000011RMi1 时，RM1,1=1,A=RMi2 时，A1,2=A4,2=1 A=0000001010100000100001011i3 时，A 的第三列全为0，故 A 不变i4 时 A1,4=A2,4=A4,4=1 A=0000001010100000101001011i5 时，A 的第五行全为0，故 A 不变。所以 t(R)=,。十、证明 15%1、（7 分）证明：设,21naaaA，,A全序集。若,A不是良序集，那么必有一子集)(BAB，在 B中不存在最小元素，由于B是一有限集合，故一定可找出两元

35、素x,y是无关的，由于,A是全序集。Ayx,所以 x,y必有关系，矛盾。故,A必是良序集。2、（8 分）证明：设ZXfgZYgYXf:,:,:，Zz由于ZXfg:满射，故必有Xx使得zxfg)(，由复合函数定义知，存在Yy使得yxf)(，又因为文档编码:CP5M8S6N6L5 HY10J7U6V1D4 ZW9R9H3E5G1文档编码:CP5M8S6N6L5 HY10J7U6V1D4 ZW9R9H3E5G1文档编码:CP5M8S6N6L5 HY10J7U6V1D4 ZW9R9H3E5G1文档编码:CP5M8S6N6L5 HY10J7U6V1D4 ZW9R9H3E5G1文档编码:CP5M8S6N6
