Namely , the volumetric - scan data of two weather radars are applied after they are projected onto a predetermined co - plane by an interpolation . to some extent , the technique settles the difficulty that the time and the space are not accordant by using two weather radars in volumetric - scan 为了便于分析比较双雷达联合探测资料，使用了一种共面投影技术，即将双雷达联合探测的体积扫描资料利用某种插值方法插值到某一共面上。
Re - projection and smooth - transition technology is the kernel of panorama - based virtual reality system . the policy of zooming middle image is introduced to achieve approximate smooth transition animation . an efficient technology of re - projection template is presented in this paper 反投影技术和视点间的平滑过渡技术是基于全景图的虚拟现实系统中的核心技术，本文提出一种简化的策略，通过缩放中间过渡图像得到近似的插值图像，实现了视点间的平滑过渡。
Combining with the practical project , the development of an instrument for multi - channel harmonic detection and analysis were described in the third chapter , including the system structure , hardware and software of the device . then the technology of multi - channel data gathering was discussed , and some key techniques have been presented including high precision 、 high speed sampling of the voltage and current , fast flourier transform ( fft ) , data compression and storage techniques , planar graphic fitting , three dimensional graphic projection , multithreading and the computer graphics techniques 第三章结合多通道谐波监测及故障录波一体化装置的研制这一课题,介绍了装置的体系结构和硬件、软件构成,详细介绍了在装置研究过程中所提出的关键技术,主要包括电流电压信号高精度、高速采样技术,快速傅立叶变换fft 、数据压缩存储技术,多线程技术,二维图形拟合、三维图形投影技术及海量存储技术,计算机图形技术等。
The algorithm ' s ideal is benint from the ideal of generalize projection technique and strongly subfeasible direction algorithm . it can be approximately describe as follows : firstly , by the introductin of a perturbed parameter / / , replace the complementarity constraints with a generalized function , then ( mpec ) can be reformulated equivalently nonlinear constraints programs . secondly . combine the ideal of strongly subfeasible direction algorithm and generalized projction tech - nique , we setup a generalized strongly subfeasible direction algorithm 本学位论文结合广义投影技术和强次可行方向法思想，建立一个新算法，该算法的主要思想大致可描述如下：首先引入一个趋向于0的参数，用一个互补函数代替性质不好的互补约束，将问题等价的转化为一般的非线性约束最优化问题，然后结合广义投影技术和强次可行方向法思想，建立一个广义强次可行方向算法
