In 110 Xinjiang unrelated healthy Uygur subjects, 27 alleles were detected in HLA-B loci. Of them, B * 35 and B * 51 were the most common alleles with an allele frequency of 0.1136 and 0.1136, respectively; while B * 41, B * 56 and B * 78 were the rare alleles with a frequency of 0.0045, 0.0045 and 0.0091, respectively. Frequencies of "Caucasoid origin" HLA alleles such as B * 08, B * 35 and B * 50 in Xinjiang Uygurs were higher than other ethnic groups in China.

For example, HLA associations with vitiligo include HLA-DR4 in Caucasian Americans, DR4 and DQW3 in black Americans, DR4 and DR6 in a Dutch caucasoid population, DR7 and DQW3 in north Italians, DR7 in Omanis, DR1 in Hungarians, DRW12 in north Germans, and DW7 in Slovakians. Negative association of DR1, DR3 and DR52 were observed in north Italians. With the DNA typing of HLA, it was found the frequencies of HLA-DRB1〓0701, DQB1〓0201, DPB1〓1601 alleles were significantly increased in Slovak patients and DRB4〓0101 were increased in Dutch patients.

Researched influence of frequency on characteristic of electromagnetic wave transmission in tunnels, and analyzed characteristic of electromagnetic wave transmission in circular, arches and curved tunnels by method of metal wave guide, and gives approximate formulas of attenuation rate. Main conclusions we obtain are as follows: in circular,rches tunnels, if frequency is higher, attenuation rate is smaller, it is beneficial for EM waves to transmit, in curved tunnel, higher frequency, more attenuation rate ...
研究了频率对井下电磁波传输特性的影响,采用金属波导法分析了圆形、拱形及弯曲隧道中电磁波的传输特性并给出衰减率近似公式,得出主要结论:在圆形和拱形隧道中,频率越高,衰减率越小,越有利于电磁波的传播;在弯曲隧道中,频率越高,衰减率越大,不利于电磁波的传播;通过特性曲线与井下实验数据相比较得出在900MHz左右为井下无线通信系统传输信号最佳频段。
