基本解釋[測(cè)繪科學(xué)技術(shù)]楔形投影英漢例句雙語例句Sphenoid sinus dilated forward surrounding manifests as parasphenoid sinus air cavities in lateral projection.蝶竇向周圍擴(kuò)展有時(shí)在側(cè)位片上表現(xiàn)為蝶竇傍氣腔。Sphenoid projection, a projection has more projective centers which are the crossing points intersected by minor axis of the ellipsoid and the parallel planes.楔形投影是以過該點(diǎn)緯線所在平面與橢球短軸交點(diǎn)為投影中心作中心投影。sphenoid projection更多例句專業(yè)釋義測(cè)繪科學(xué)技術(shù)楔形投影In this paper, we adopt two projection modes: Sphenoid projection and the projection according to the normal of ellipsoid surface.本文主要采用了兩種投影方式將橢球面上的各點(diǎn)按經(jīng)緯網(wǎng)格投影到相應(yīng)的切割平面上：楔形投影和按各點(diǎn)的橢球面法線進(jìn)行投影。
