FAST台址区广泛分布大量岩堆,厚度大、稳定性差,如何解决台址开挖过程中岩堆的稳定性,是关系到FAST安全稳定运营和台址开挖投资控制的关键。在岩堆现场调查的基础上,通过岩土工程模型试验,探索验证洼地岩堆的特有性质,并对不同支挡方式在该种条件下的稳定性和工作性能进行实验和分析,为FAST台址区岩堆的治理设计提供依据。
Application Note - AN 111 The time of flight mass spectrometer (TOF-MS) is the only system capable of providing high speed acquisition rate to collect sufficient information (15-20 points/peak) for trustworthy peak reconstruction, enabling an accurate recognition and quantification of unknown and co-eluting peaks typically present in complex samples [3].
