双向转换 meaning in Chinese
bilateral switching
Examples
- And any numeric type
和任何numeric类型之间的双向转换 - Conversions from a data type or object type to a type derived from it
之间的双向转换从数据类型或对象类型到其派生类型的转换 - The constitutions and principles of position of gps > glonass and beidou navigation system are described all around in this article , and the following technologies are studied and realized : communication between com ports with oop technology , compound navigation with gps and glonass . calculate velocity , pseudorange difference , smoothing pseudorange with the carrier - phase and models to correct error are also done ; the transforms between wgs - 84 and pz - 90 , as well as wgs - 84 and beijing54 coordinate system ; the technologies to display and manage bitmap , vector map based on mapx also ; conversion of data formats between gjb and mif data format of maplnfo corp . arithmetic of creation dem data based on contour line data from 1 - . 25000 map data with gjb format . texture the surface of terrains with corrected aviation image
本文全面介绍了gps 、 glonass 、北斗导航系统的组成、定位原理，研究并实现了面向对象的串口通信技术、 gps + glonass组合导航、测速及伪距差分、相位平滑伪距差分以及有关误差的模型改正、 wgs ? 84和pz ? 90 、 wgs ? 84和北京54坐标系的坐标转换、栅格地图的显示和管理、基于mapx的矢量地图的显示和管理、 1 : 25万军标数据和mapinfo的mif数据格式双向转换、基于军标数据的dem生成算法、基于opengl的三维地形构造、航空图像纹理地形表面、三维坐标量算、虚拟现实模拟导航、三维地形的层次细化算法以及数字图像处理中的图像增强、几何变换、影像匹配等技术。 - Supported by national 863 / cims high tech program - semantic integration of enterprise heterogenous data source , this paper takes xml as a public model and studied the conversion technology among heterogeneous relational database systems by means of bidirectional reversible conversion between relational and xml
本文结合国家863 cims研究项目“基于语义与模型的企业异构数据源集成关键算法与实现技术” ，研究以xml为公共模型，通过关系数据库与xml的可逆双向转换，建立异构关系数据源的统一转换工具。 - So , in this paper , it does the research of the bidirectional conversion between uml and xyz / adl . in this way it combines the oo visual modeling language and formal method based on temporal logic together to describe software architecture , and so to find how to apply the formal method to real software development to promote the research not only on main technologies in software but also on formal method
基于此,本文开展了对基于时序逻辑的软件体系结构描述语言xyz / adl和uml之间的双向转换问题的研究,通过研究二者之间的转换,实现将基于时序逻辑的形式化方法与面向对象的可视化建模语言相结合描述软件体系结构,来探讨如何将形式化方法应用于实际的软件开发过程中,这样不但能促进对当前软件主流技术的研究,而且能促进对形式化开发方法的研究。
