查询词典 implicit difference scheme

A new scheme of frequency measurement in hydro-turbine governor is introduced in this paper. Instead using single-chip computer or P LC high-speed count module, it utilizes the interrupt functions and high-speed counter in the PLC base unit and peripheral circuit. With enhanced reliability and reduced cost, the governor designed in this scheme shows good application pr ospect.

介绍一种在水轮机调速器中实现频率测量的新方案，该方案不需要单片机，也不需PLC的高速计数模块，它是利用PLC基本单元的中断功能、内藏的高速计数器及相应的外围电路得以实现，从而既提高了调速器的可靠性，又降低了其成本。

The synthesis scheme we developed can deal with changes in visibility, produce perspectively correct views and handle the distortion around the circumferences in the synthesized views. In our scheme, the area without corresponding points was first determined by using Fourier transformation in order to deal with distortion problem, within the mutual overlapped area the z-buffer values of matched key points were computed so that the visibility in novel views can be handle correctly, lastly the common points in new views are rendered through epipolar geometry constraint.

算法的步骤为：利用傅立叶变换方法确定相邻源图像无对应点的区域；然后，利用尺度空间和相位一致原理在共同区域提取及匹配边缘上的关键点，计算其深度值，并在新图像中由该值判别虚拟图像中的可见性；再由关键点恢复极线约束，通过极线间的位置和颜色插值生成虚拟图像中有对应区域的一般点；在确定极线位于无对应点区域段后，利用加权平均或放大插值的方法实现了源图像无对应点区域在虚拟图像中的自然过渡。

We constructed a finite volume scheme of fifth order Hermite type with high accuracy for twopoint boundary value problems, choosing trial and test spaces as the fifthorder finite element space of Hermite type and the piecewise linear function space respectively. We didn't use higher derivatives as interpolation conditions, which is the same as the thirdorder finite element of Hermite type, but the scheme obtained had higher accuracy.
