抗生素  近海  前处理技术  综述  antibiotics  coastal  pretreatment techniques  review  The widespread and massive usage of antibiotics for the prevention and treatment of diseases in human and animals have resulted in their continuous discharge into the environment, and finally, into the coastal environment through various pathways. Accumulation of antibiotics in aquatic organisms poses a great threat to ecological and human health, especially because it facilitates the generation and spread of bacterial resistance. Given the diverse range of antibiotics with various features, as well as their presence at low concentrations in the environment, it is imperative to develop pretreatment techniques for antibiotics in various matrices. In this paper, the pretreatment methods proposed in recent decades for antibiotics in coastal water, sediment, and biota are summarized, with emphasis on commonly used methods such as solid-phase extraction, solid-liquid extraction, matrix solid-phase dispersion, and QuEChERS. Additionally, the potential factors influencing the extraction performance and clean-up efficiency are analyzed. The advantages and disadvantages of the methods and their development are finally discussed.

Most conventional spacious solar photoelectric detection systems suffer from unexpected stray light. This paper demonstrates the effects on photoelectric detection system bring out by stray light. On this foundation  build up evaluation index of stray light system  to search the reasonable programme to eliminating stray light. A detailed telescope system geometry model was created  and scatter models were create for telescope and enclosure components. By the means of designing the structure of main baffle  baffle vane and the coating technology. In order to verify the prosperity of structure that designed  we utilizes software to analysis opto-mechanical model. we utilizes software to analysis opto-mechanical model. The simulations show that point source transmittance of the system is thus reduced by up to two orders of magnitude between 10-8 and 10-10. Meanwhile  the experiment obtains clean detection data which satisfies the system requirements. Stray light has been suppressed effectually  and so measurement precision was improved from detection graphics. (2012) Trans Tech Publications.
