光截面 meaning in Chinese

optical cross section
optical cross-section

Thirdly , the cluster - cluster aggregation model is used to study the possible structure of aggregated smokescreen particle . we also develop the mathematical radiation extinction model of aggregated particle based on t - matrix method . associated with monte carlo method , another computer program is designed to simulate the extinction cross section and scattering cross section of actually aggregated particle
本文还将“凝聚体?凝聚体”凝聚模型应用于烟幕凝聚现象研究，模拟出了烟幕凝聚粒子的可能结构，并且根据t矩阵方法发展了凝聚粒子消光特性的计算方法，结合montecarlo方法，编写了能够模拟实际烟幕凝聚粒子消光截面、散射截面的计算程序。
Secondly , the mathematical radiation extinction model of nonspherical particle is developed based on t - matrix method , and a computer program is designed to calculate the extinction cross section , scattering cross section , absorption cross section and scattering phase function of fixed or randomly oriented axially symmetric particle
然后根据t矩阵方法，采用回转体微粒消光特性的计算模型编制出的相应程序，对固定取向和随机取向的非球形回转体微粒的消光截面、散射截面、吸收截面及散射相函数进行了计算。
