  1. We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips, and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem, and rays are rather rich in secondary xylem

    結果表明:氣生不定根具有以下結構特徵和發育特點: ( 1 )根為二原型,側根正對著木質部發生; ( 2 )幼根內皮層細胞具凱氏帶加厚,維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞; ( 2 )根中無髓和樹脂道; ( 4 )次生結構發生於根毛區,維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成; ( 5 )中柱鞘和栓內層細胞富含單寧類物質; ( 6 )次生韌皮部有石細胞,次生木質部射線發達。
  2. Study on branchlet surface sculpture does not reveal any hair - like structures as recorded by previous authors ; only some warty cuticles on the ridges and variable stomata in the grooves are noted. the surface of synangium in ephedra has secondary sculpture while the lip of the openings of synangium resembles the cerebral waves

    對小枝表面掃描電鏡下的微形態構造的研究並沒有發現前人報道的毛狀體特徵,而只有一些疣狀角質突起和有變異的氣孔,同時注意到,麻黃屬植物的小枝表面特徵受到生境、發育階段的影響。
  3. While slug structure is leaving from computing domain, the successive disturbance develop in downstream direction, the legs of hair - pin vortex approach the wall continuously and induce vortex structures near the wall. the evolution of this near - wall vortex structures brings the secondary transition to turbulence in the pipe flow

    隨著塞流結構流出計算域,后繼擾動向下游繼續發展,表現為發卡渦的渦腳向壁面不斷貼近,進而誘發近壁渦結構,近壁渦結構的進一步演化促使圓管流動出現二次轉捩,發展到了湍流階段。
  4. Based on these parameters, the present work studies the transition of pipe flow with the different amplitude of psb disturbance. the present work simulates the whole time - space process of the transition from laminar to turbulence and secondary transition phenomenon in pipe flow for the first time. the main structure in pipe flow transition is hair - pin vortex ; the evolution of hair - pin vortex is related with the transition of pipe flow

    在這一組參數下,本文研究了不同擾動幅值的psb擾動作用下圓管流動的轉捩過程,首次給出圓管流動從層流轉捩到湍流的時空演化全過程,發現了圓管流動的二次轉捩現象,並進一步揭示了發卡渦是圓管流動轉捩中的主要結構,流動的轉捩過程與發卡渦的演化直接相關。
  5. Herein is reported a case of reversible alopecia universalis, with complete hair loss extending to the whole body, secondary to peg - ifn [ alpha ] - 2b and ribavirin combination therapy for chronic hcv infection

    本文是報告一例可逆性普脫,在聚乙二醇干擾素與利巴韋林聯合治療慢性丙型肝炎病毒感染過程中,患者全身毛發完全脫落。
