rachitis
The feathers attached to the arms and the tail evidently possess the structures of “ modern feathers “ , which consisting of the central shafts ( rachis ) and parallel barbs . dromaeosaurids are unusual group of maniraptoran theropods . they share many similar or the same features with archaeopteryx or other primitive birds , such as : u - shaped furcula , uncinate process , laterally facing glenoid of shoulder girdle , comparatively long forelimb , large semilunate carple , retroverted pubis , ascending process of astragalus , and “ modern feathers “ with rachis and barbs etc . these facts indicate not only that dromaeosaurids had developed many bird - like characters in course of the advanced maniraptorans toward birds , but also that there seemed to be the co - evolutionary trend between the feathers and the skeletal bones 奔龍類是一類較為特殊的手盜龍類( maniraptora ) ，它具有許多與始祖鳥archaeopteryx甚至其它早期鳥類相似或接近的特征，主要表現在：叉骨u形與始祖鳥和孔子鳥類的相同，背肋鉤狀突在孔子鳥類和個別反鳥類中也存在，肩臼窩絕大部分指向側方類似于始祖鳥，肩胛骨與烏喙骨間的夾角非常接近90也和始祖鳥的相似，前肢從比例上講顯得較長，大的半月形腕骨使肘部能向側方折過來，恥骨伸向后下方，距骨上升突與原始鳥類中的為同源結構，羽毛已有顯著的分化且具備了現代羽毛的基本結構等等。
It is mainly characterized in the triangular - lanceolate leaves which are green but white with dark green reticulation along the midrib and more or less truncate at base ; the flowers are erect on the rachis and half - opened ; the lip is tripartite , glabrous , more or less urceolate in side view ; the hypochile is saccate , ovoid and big while the epichile is relatively tiny , reflexed , undivided and transversely oblong or subreniform 本種之主要特征為： ?呈三角?披針形， ?面?色，沿中?有白色斑塊， ?基多少呈截形；花直?于花軸，半張；唇瓣呈三段? ，平?無毛，側視時多少呈壺型；基段片囊? ， ?形，巨大，先段片相對微小、反卷， ?再細?而呈橫向橢圓形。
Then using ecbp21 antibody and immunogold transmission electron microscopy method , we studied the subcellular localization of ecbp21 . the results indicated that the gold particles were mainly localized in the cell wall in callus cells and rachis cells of angelica dahurica . these results indicated that ecbp21 mainly localized in cell wall , which provide a direct evidence of the extracellular existence of ecbp21 . furthermore , using ecbp21 antibody and immunohistochemical method , we studied the organic specially distribution of ecbp21 , the results indicated that ecbp21 distributed in all organize , but it distributed more in leave n flower rachis than in leafstalk and root 首先，構建了ecbp21表達載體，誘導了重組蛋白的表達，并通過膠回收法獲得了大量純化重組ecbp21蛋白，制備了高效價、高特異性抗體；隨后，利用ecbp21抗體，結合免疫膠體金電鏡定位技術進行了ecbp21亞細胞定位研究，結果顯示：在白芷愈傷組織細胞和花序軸細胞中金顆粒主要分布在細胞壁區域，而在細胞內未發現或僅有少量金顆粒分布，表明ecbp21蛋白主要定位于細胞壁區域，這為細胞外cambp ( ecbp21 )的胞外存在提供了直接證據：進一步，利用ecbp21抗體，通過免疫組織化學分析研究了ecbp21組織特異性分布狀況，結果表明ecbp21在白芷各組織中均有分布，但在葉、花、花序軸中分布較多，而在葉柄、根中分布較少。

“ x - ray gaze small cut extirpating soft organism eyewinker “ got the fourth prize in military field ; “ research and application of wild war one - time operation bandage “ got the second prize ; “ making of rabbit paralyze modal and rachis transplant experiment “ the fourth prize of technical progress “ x -線直視下小切口摘除深部軟組織異物”獲軍內科技進步4等獎。 “野戰一次性手術敷料包研制及應用”獲全軍科技二等獎。 “家兔癱瘓模型的制做以及胎兔脊髓移植的實驗研究”獲得軍內科技進步4等獎。
Leaves bipinnate , 10 - 25 cm long , usually with 2 pairs of pinnae , rachis often ending in a tendril ; pinnae with 2 - 4pairs of leaflets and terminal tendrils ; leaflets opposite , oblong or long obovate , 3 - 9cm long , 1 . 5 - 4cm wide , apex obtuse or emarginated , base slightly oblique 葉為二回羽狀復葉，長10 - 25厘米，葉軸先端常變為?須，羽片通常2對，頂生1對羽片變為?須；小葉2 - 4對，對生，長橢圓形或長倒卵形，長3 - 9厘米，寬1 . 5 - 4厘米，先端鈍、微凹，基部略偏斜。
Sinosauropteryx ( compsognathids ) , beipzaosaums ( therizinosaurids ) and shuvuuia ( alvarezsaurids ) have the filament - like protofeathers that lack the rachis and barbules …具有最為簡單的原始羽毛狀構造，這種構造不具備羽干及羽小枝；而proto17vaeoptepe 、 ca 。 dhtepe 。

Likewise , a plumulaceous tuft of barbs evolved before the pennaceous feather with a rachis because the rachis is formed by the fusion of barb ridges 同樣的，絨羽的羽枝簇比擁有羽軸的正羽更早演化出來，因為羽軸是由羽枝脊接合而成。
Spadix rachis flat , margin with bract - like appendages ; flowers small , monoecious , in 2 series on rachis , apetalous 肉穗花序軸扁平，邊緣有苞片狀附屬物；花小，單性，雌雄同株，呈2列排列于花序軸上，無花被。
