scattering object造句
例句與造句
- 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
并指出體積光柵效應(yīng)對透射全息衍射效率是有貢獻的,討論了影響散射物體全息衍射效率的問題,最后指出在一般情況下,調(diào)制折射率是一個很小的量,化學(xué)處理對它起著關(guān)鍵性的作用。 - 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
相對于一些傳統(tǒng)的方法如幾何光學(xué)方法,幾何繞射方法,彈跳射線方法有著更高的精度和更廣的適用范圍。但是由于其基于積分方程方法,需要對全局中所有的子散射體之間的相互耦合加以考慮,從而導(dǎo)致在求解電大尺寸目標的散射問題時需要巨大的存儲空間。同時由于其在譜域上嚴格積分導(dǎo)致計算量也很大。 - 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
該算法選擇基于質(zhì)心利基于代表對象方法之間的中間策略，它不用單個質(zhì)心或簇中全部對象米代表一個簇，而是選擇數(shù)據(jù)空間中定數(shù)目的只有代表性的點，這些點代表和捕捉到了簇的形狀。此外，由于引入了收縮因子使代表點向簇小心“收縮”而使該算法能夠較好地消除孤立點的影響，在處理孤立點上也更加健壯。 - It's difficult to find scattering object in a sentence. 用scattering object造句挺難的
