offset data meaning in Chinese
补偿数据
偏移数据
Examples
- The accuracy of migration image of ground - penetrating radar data is strongly related to the accuracy of permittivity distribution determined from multi - offset data
摘要地质雷达资料偏移成像的精度与地下介质介电常数分布的确定精度有直接关系。 - Because doubly linked list can dynamically distribute store place , it is used in storing the offsets data of ship . through adding and deleting the node , we can easily add the offsets data and modify the model
系统采用双链表来存储船体的型值点数据，之所以采用双链表，是因为其可以动态分配存储空间，同时可以很方便地增删节点，从而进行船舶型值点加密以及模型修改。 - To interpolate the given ship offset data , the ship - hull surface is represented successfully by nurbs . the boundary conditions computation and knots vector construction are detailed in nurbs curve and surface interpolation
本文根据船体型值表的数据，用nurbs曲面来描述完整船体曲面，对插值曲面边界条件构造及节点矢量计算进行了研究，实现了船体曲线曲面的nurbs表达。 - It can transform offsets data into control - points data and subsequently build the scenery model of ship with these control points data . the three methods all have their advantages and disadvantages . we select one of them according to the hardware of computer and the precision required
由船体的型值点生成控制点数据，再由控制点生成船体曲面，此三种表达方式各有优劣，根据硬件条件和精确度要求我们可以选择不同的船体曲面表达方式。 - As the basic concept , the first step is to modeling by ug . there is different model between propeller and commonly hardware , so we must be use curve modeling , at the same time , characteristic modeling and entity modeling in the whole process . first , we apply offset data for spline fit curve , then scanner smooth curve face
首先在三维绘图软件ug中对螺旋桨及叶片进行三维建模,由于螺旋桨的造型不同于一般零件的cad造型,故在造型过程中同时采用了曲面造型,特征造型和实体造型几种方法,先由型值数据生成样条曲线,再由样条曲线扫掠生成平滑的曲面,最后通过圆整?延伸得到螺旋桨的三维模型。
