【摘要】 为了探测和研究大气能见度与湍流特征,应考虑大气湍流气团运动与气溶胶粒子之间存在的复杂关系。但传统测量仪器只能单独测量能见度或者大气湍流,忽略了二者之间的相互作用。基于布格-朗伯定律与光强起伏原理,设计并实现了大气能见度与湍流同步测量系统。实测结果表明系统可用,与同行业已有仪器测量结果相对误差为6.7%。相对于传统仪器,其设计更为简捷,成本更加低廉。更多还原

【Abstract】 In order to detect and study atmospheric visibility and atmospheric turbulence characteristics,the complex relationship between the motion of atmospheric turbulence air mass and aerosol particles should be considered. However,traditional instruments only measure visibility or atmospheric turbulence separately,ignoring the interaction between them. In this work,a measurement system capable of simultaneously detecting that atmospheric visibility and atmospheric turbulence has been designed,based on Bouguer-Lambert-Beer law and the fluctuation principle of light intensity. The measurement results show that the system is available,also simpler and cheaper than traditional products. The relative error is 6.7% compared with the measurement results of existing instruments.更多还原
