relative scatter intensity meaning in Chinese
相对散射强度
Examples
- In the first part , the basic knowledge of particle scattering in meteorology and physics was introduced . the particles to be discussed include aerosol particles , fog droplets and raindrops and the em wave band in the discussion is near - infrared . in the second part , the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles , the result shows that in the visibility measurement meter using forward - scattering method , when the working wavelegth is between 0 . 8 m ~ 2 m , the scattering angle is between 25 ~ 40 , the distinguishability and the relative scattering intensity would be better than those under other conditions . in the third part , the superellipsoid was used to describe a wide range of shapes such as spheres . ellipsoids and cylinders . an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced , and the scattering characteristics of non - spherical atmospheric particles was investigated with this method
计算结果表明，从相对散射强度、同一方向上不同粒子散射的可区分程度来看，在散射式能见度探测仪器中，工作波长介于0 . 86 m 2 m ，探测角度选取前向25度40度时，探测的结果将会是比较理想的。第三部分中，使用超椭球方程来统一描述各种非球形粒子的形状，然后使用t矩阵方法计算了一些形状的非球形粒子的近红外散射特性。另外，在本文中还针对球形粒子的散射场提供了一种三维可视化方法，使对散射场强度的空间分布的理解更加简单，直观。
