This paper presents a review of the position-sensitive detector(PSD) sensor, covering different types of PSD and recent works related to this field. Furthermore, it explains the theoretical concepts and provides information about its structure and principles of operation. Moreover, it includes the main information about the available commercial PSDs from different companies, along with a comparison between the common modules. The PSD features include high position resolution, fast response, and a wide dynamic range. These features make it suitable for various fields and applications, such as imaging, spectrometry, spectroscopy and others.

The kinetics of criegee intermediates are important for atmospheric ***,the quantitative kinetics of criegee intermediates are still very limited,especially for those with hydroxy ***,we calculate rate constants for the unimolecular reaction of E-glycolaldehyde oxide[E-hydroxyethanal oxide,E-(cH_(2)OH)cHOO],for its reactions with H_(2)O and(H_(2)O)_(2),and for the reaction of the E-(cH_(2)OH)cHOO…H_(2)O complex with H_(2)*** the highest level of electronic structure,we use W3X-L//ccSD(T)-F12a/cc-pVDZ-F12 for the unimolecular reaction and the reaction with water and W3X-L//DF-ccSD(T)-F12b/jun-cc-pVDZ for the reaction with 2 water *** the dynamics,we use a dual-level strategy that combines conventional transition state theory with the highest level of electronic structure and multistructural canonical variational transition state theory with small-curvature tunneling with a validated density functional for the electronic structure.

基于合约、借方和贷方三方面特征设计农户民间放贷离散选择实验,依据陕西、山东两省289户农户实验数据,构建效用相互依赖模型考察农户民间放贷选择偏好的内在机理,采用Mixed Logit模型探究农户选择偏好及其异质性来源。研究结果表明,农户民间放贷选择中经济理性与道义理性偏好并存。其中,经济理性体现为农户偏好向亲戚或信用水平较高的借方放贷,农户手头资金紧张时放贷意愿减弱;道义理性体现为农户偏好向经济情况比自己差、曾与自己有过互动经历且用途为生活性应急需求的借方放贷,农户拒贷有压力时放贷意愿增强。进一步研究发现,农户民间放贷选择偏好存在异质性,表现为受教育程度会强化放贷农户经济理性偏好,家庭收入会强化放贷农户道义理性偏好,风险偏好型放贷农户的道义理性偏好更弱,而山东省放贷农户的经济理性和道义理性偏好均高于陕西省。
