scattering object meaning in Chinese
散射体
Examples
- This paper also discussed the factors that influenced the diffraction efficiency of scattering object , and proposed the amount of refraction index modulation was very small , the diffraction efficiency was mainly determined by chemical treatment
并指出体积光栅效应对透射全息衍射效率是有贡献的,讨论了影响散射物体全息衍射效率的问题,最后指出在一般情况下,调制折射率是一个很小的量,化学处理对它起着关键性的作用。 - On the other hand , the multi - level fast mutipole algorithm ( mlfma ) which based on the integral equation method can obtain the result with great accuracy , but this method accounts in all the couplings between every sub - scatter objects , it needs much more to store all of the information , and because of the rigorous integral on the spectrum space the computational complexity is also enormous
相对于一些传统的方法如几何光学方法,几何绕射方法,弹跳射线方法有着更高的精度和更广的适用范围。但是由于其基于积分方程方法,需要对全局中所有的子散射体之间的相互耦合加以考虑,从而导致在求解电大尺寸目标的散射问题时需要巨大的存储空间。同时由于其在谱域上严格积分导致计算量也很大。 - This algorithm adopts a middle ground between centroid - base and all - points - based approaches . instead of using a single centroid or all points to represent a cluster , a fixed number of representative points in space are chosen , these points represent and capture the geometry and shape of the cluster . in addition . the representative points of a cluster are generated by first selecting well - scattered objects for the cluster and then " shrinking " or moving them toward the cluster center by a specified fraction , or shrinking factor . the shrinking helps dampen the effects of outliers . therefore , cure is more robust to outliers
该算法选择基于质心利基于代表对象方法之间的中间策略，它不用单个质心或簇中全部对象米代表一个簇，而是选择数据空间中定数目的只有代表性的点，这些点代表和捕捉到了簇的形状。此外，由于引入了收缩因子使代表点向簇小心“收缩”而使该算法能够较好地消除孤立点的影响，在处理孤立点上也更加健壮。
