三倍的

After rigorously mathematical deduction, some valuable conclusions are drawn: at the multiple times of symbol period, discrete peaks of the PACA function appear with 3 peaks in group, which includes a larger peak located in the middle and the other smaller two located symmetricly beside the larger one. The distance between small peaks is modulation offset of pulse position PPM.

经过严格数学推导，指出了TH-UWB信号的PACA函数不但在字符周期整数倍处出现离散峰值，而且按三个峰值(一大峰值左右对称出现小峰值)成对出现，大峰和小峰的间隔就是PPM调制时间偏移。

Suspects of DS and 26 cases of fetal amniocytes come from pregnant woman with high risk of DS were undertook to analysis 10 STR loci simultaneously by PAGE and silver staining or automated fluorescent laser activated detector sequencer (ABI310). 6 suspects of DS were determined as DS by trisomic triallelic with a ratio of 1: 1: 1 and the other STR loci show nonnal diallelic pattern with a ratio of 1: 1 or homozygous with two alleles of the same size. The other one suspect determined as DS by 7 STR marker showing trisomic diallelic band or peak.
