40 blind samples were examined by AGAR gel precipitation (AGP), hemagglutination inhibitory (hi) test and reverse transcription-polymerase chain reaction (RT-PCR).
对40份盲样采用琼脂扩散试验(agp)、血凝抑制试验(H I)和反转录聚合酶链反应(RT - PCR)进行了检测。
Reverse Engineering can be used to reconstruction the prosthesis. The 3d surface information of the prosthesis can be collected by the laser scan system and there is no blind area.
利用反求工程可以实现修复体的三维重建，激光扫描法可以快速收集修复体的三维表面信息，精度高，并且没有测量盲区。
