摘要地質(zhì)雷達(dá)資料偏移成像的精度與地下介質(zhì)介電常數(shù)分布的確定精度有直接關(guān)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
系統(tǒng)采用雙鏈表來存儲船體的型值點(diǎn)數(shù)據(jù)，之所以采用雙鏈表，是因?yàn)槠淇梢詣討B(tài)分配存儲空間，同時(shí)可以很方便地增刪節(jié)點(diǎn)，從而進(jìn)行船舶型值點(diǎn)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
本文根據(jù)船體型值表的數(shù)據(jù)，用nurbs曲面來描述完整船體曲面，對插值曲面邊界條件構(gòu)造及節(jié)點(diǎn)矢量計(jì)算進(jìn)行了研究，實(shí)現(xiàn)了船體曲線曲面的nurbs表達(dá)。 - 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
由船體的型值點(diǎn)生成控制點(diǎn)數(shù)據(jù)，再由控制點(diǎn)生成船體曲面，此三種表達(dá)方式各有優(yōu)劣，根據(jù)硬件條件和精確度要求我們可以選擇不同的船體曲面表達(dá)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
首先在三維繪圖軟件ug中對螺旋槳及葉片進(jìn)行三維建模,由于螺旋槳的造型不同于一般零件的cad造型,故在造型過程中同時(shí)采用了曲面造型,特征造型和實(shí)體造型幾種方法,先由型值數(shù)據(jù)生成樣條曲線,再由樣條曲線掃掠生成平滑的曲面,最后通過圓整?延伸得到螺旋槳的三維模型。 - It's difficult to find offset data in a sentence. 用offset data造句挺難的
- Abstract : mechanism of optimal cutting movement track for stone sawing machine was analyzed . the system mathematical formula was established , the calculation expressions of system technique parameter and the exact calculation methods of optimal offset data were reduced , and the optimization for complex movement mechanism was realized
