Abstract: The present disclosure relates to a sample rack loading system and loading method, and a chemiluminescence detector. The loading system includes: a sample rack storage device, provided with multiple sample holders for storing sample racks; a sample rack transmission device, comprising a rail component and a sample rack block piece mechanism; and a sample rack transfer device, transfers the sample racks between the sample rack storage device and the sample rack transmission device; the sample rack block piece mechanism is configured to block or unblock transmission passages of the rail component; and a guide block is arranged on the sample rack transfer device. When transfer rails of the sample rack transfer device are in abutment with the transmission passages, the guide block drives the sample rack block piece mechanism to unblock the transmission passages.

Abstract: Disclosed is a terahertz laser device based on phonon vibration excitation, including a resonant cavity composed of a hollow waveguide made of a composite film and optical lenses at both ends of the waveguide, where M represents nano-metal particles. A zinc oxide mesomorphic microsphere is used herein as a source, symmetric stretching vibration of nanosheets on the zinc oxide microsphere is excited and induced by a laser and is transmitted through elastic and electric coupling among the nanosheets, and a terahertz wave with a frequency of 0.
