fusus-
European vetchlike herb naturalized in the eastern united states having umbels of pink - and - white flowers and sharp - angled pods
一個歐洲產的巢菜狀草本植物，已在美國東部歸化，具有粉紅及白色花，成傘形花序及銳棱莢果。Palisade parenchyma takes a larger proportion than spongy tissue in mesophyll. different from other dicotyls, the cortex in c album l. is composed of mechanical tissue and assimilating tissue, which are alternately arranged with each other
藜與其它雙子葉植物不同，其莖的皮層呈明顯的機械組織和同化組織相間排列，其中同化組織形態類似海綿組織細胞；機械組織突起成棱。In the application of mini - micro - robot visual perception, there is a need for fish - eye lenses for capturing wide field of view for navigation. though fish - eye lenses provide a wide field of view ( 180 ), they introduce significant distortion in images and the acquired images are quite warped, which makes conventional camera calibration algorithms no longer work well. this paper presents an accurate calibration framework for fish - eye lens ( a high distortion lens ) camera stereo vision system. the accurate calibration model is formulated with radial distortion, decentering distortion and thin prism distortion based on the fisheye deformation model. using fish - eye and non - linear camera model, the author employs levenberg - marquardt method to realize precise non - linear calibration for wide - view - scene dense depth image recovery
魚眼鏡頭成像立體視覺系統在微小型機器人視覺導航和近距離大視場物體識別與定位中有著廣泛的應用.盡管魚眼鏡頭攝像機具有很大的視場角（接近180 ） ，但同時也引入嚴重的圖像變形，常規的攝像機標定方法無法使用.該文提出一種標定魚眼鏡頭攝像機立體視覺系統的方法.在魚眼鏡頭變形模型的基礎上，通過考慮魚眼鏡頭成像的徑向變形、偏心變形和薄棱鏡變形，建立了魚眼鏡頭成像的精確成像模型，然後，利用非線性迭代演算法，精確求解攝像機外部參數、內部參數.實驗表明，使用該方法得到的立體視覺系統參數滿足精確恢復大場景稠密深度圖的要求As increasing the concentration of c4s, the amount of com crystals with a hexagonal prism decreased and that with a thin hexagonal slice increased. when the concentration of c4s was 0. 50 mg / ml, all the calcium oxalate crystals were thin hexagonal slice com crystals. however, as the concentration of l - glu increased from 0. 01 to 0. 50 mmol / l, the hexagonal prism - like com crystals gradually transformed to com crystals with one or two ( 010 ) crystal face disappearance
不同形貌晶體的分佈受添加物濃度的影響： c _ 4s濃度的增加使com晶體由六稜柱形晶體轉變為六邊薄片狀晶體，特別是當c _ 4s濃度為0 . 50mg ml時， com晶體全部轉變為六邊薄片狀晶體； l - glu濃度的增加使com晶體由六邊稜柱晶體逐漸轉變為多棱「不規則」晶體。Physical seate : our company ' s quartz sand is made of natural quartz roes after ceasing, sieving and water scrubbing and takes on multi - prismatic shape and pure white color with no impurity
物理狀態：我公司生產的石英砂，是天然石英礦經破碎、篩選、水洗而成，多棱形色純白、無雜質。分享友人
