sinusoidal approximation 中文意思是什麼

sinusoidal approximation 解釋
正弦式近似法
  1. This dissertation emphasizes on the creation of image space, the author present a display system in which screen moves with a sinusoidal velocity profile to create image space. this paper uses linear approximation to make the system display homogeneous graphic and analyzes worst - case positional error due to linear approximation

    本論文重點分析了顯示單元中成像空間的構造,提出屏幕按正弦曲線運動的方式來構造成像空間,用線性近似的方法得到均勻的圖像,並分析了由於線性近似帶來的最大屏幕位置誤差。
  2. As for nonlinear problem, the approximation schemes and the error analysis of pti are investigated, in order to avoid the computation of inverse matrix, the pti with dimensional expanding is proposed. the methods of constant, linear, sinusoidal approximation are proposed for the transformation of non - homogenous terms

    通過增維技術,該演算法將非齊次方程齊次化,從而避免了矩陣求逆,並給出非齊次項常數近似、線性近似和正弦餘弦近似的處理方法。
