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.

将10个STR位点的PCR产物用聚丙烯铣胺凝胶电泳和银染法或基因片段扫描法进行检测，结果从23例可疑患者中发现7例DS患者，其中6例均出现三条带图谱，1例虽未发现3条带图谱，但除纯合子外其余位点均表现为双倍剂量（2：1）的2条带图谱。26例胎儿羊水细胞STR基因型均表现为正常2条带图谱（1：1），表明为非DS胎儿。

Hamamatsu R2868 is a UV TRON ultraviolet detector that makes use of the photoelectric effect of metal and the gas multiplication effect.

Hamamatsu R2868 是利用紫外线 TRON 通过金属的光电效果和瓦斯乘法效果来发现火星源。

As a rapid calculation of radioactive shield attenuation in truncated cone, the cross points penetrated through the truncated right angle cone shielded region from source points to the detector point have been studied via numerical analysis.

提出一种数值解析法计算从放射线源到评价点的放射线所穿透圆锥台形屏蔽物体的交点坐标，从而可快速预测辐射屏蔽衰减率。

A tungsten halogen lamp and a projecting lens are used to generate the collimated light. A CCD detector is used as light spot position sensor to measure the changes of the spot position at the rear focal plane of the imaging lens, and the optical angular deviation can be derived.

采用钨灯和投射透镜产生准直白光，用CCD探测器作为光斑位置传感器在成像透镜的后焦面测量光斑位置的变化，从而可得光学角偏差。
