[Genome] human chromosomes

[Yan Xiang]

Dear Sir/Madam,

     I was using Human Genome Browser and had a question about these chromosomes below(what chromosomes they are? Or contig accession numbers for them?):    

chr1_random 
chr10_random 
chr11_random 
chr13_random 
chr15_random 
chr16_random 
chr17_random 
chr19_random 
chr2_random 
chr21_random 
chr22_h2_hap1 
chr22_random 
chr3_random 
chr4_random 
chr5_h2_hap1 
chr5_random 
chr6_cox_hap1 
chr6_qbl_hap2 
chr6_random 
chr7_random 
chr8_random 
chr9_random 
chrX_random 
 
Below are some chromosomes I got from NCBI webpage. Is there any relationship between UCSC chromosomes up and the NCBI chromosomes below?
